Eye Pain or Chest Symptoms With Ankylosing Spondylitis: Why They Need a Prompt Check

It starts on a Saturday morning, the way these things do. One eye feels gritty, then achy, then oddly bruised behind the brow. The bathroom light is suddenly too bright. A quick look in the mirror shows a pink eye with a pupil that seems a little smaller than its partner. For most people that would be a minor nuisance. For someone living with ankylosing spondylitis, it is a phone call that should be made that day.

People with ankylosing spondylitis learn to live alongside back stiffness and the slow rhythm of flares. What surprises many is that the same immune process can appear somewhere it seems to have no business being: the eye, or the chest. Ankylosing spondylitis eye pain from uveitis is not rare, and chest discomfort is common enough that most patients will eventually wonder about it.

This guide explains what is happening in those two places, why the eye in particular gets a fast lane at the clinic, and how to tell the difference between a symptom you can mention at your next appointment and one that should not wait.

What actually happens inside the eye during uveitis?

The uvea is the middle layer of the eye, a thin band of blood-rich tissue that includes the iris (the colored ring), the ciliary body behind it, and the choroid lining the back wall. Uveitis simply means this layer is inflamed. In ankylosing spondylitis, the inflammation almost always sits at the front, in the iris and ciliary body, which is why doctors use the terms anterior uveitis and iritis almost interchangeably.

Picture the iris as a shutter that normally floats in clear fluid. When it becomes inflamed, tiny blood vessels leak white blood cells and protein into the front chamber of the eye. That cloudy fluid scatters light, which is why vision blurs. The iris muscle itself goes into spasm, so the pupil clamps down and aches, particularly when light asks it to move. The ciliary body, which helps focus the lens, also cramps, adding a deep, boring pain that many people describe as sitting behind the eye rather than on its surface.

Two things make this different from ordinary conjunctivitis. First, the redness tends to concentrate in a ring around the colored part of the eye rather than spreading uniformly across the white. Second, there is little or no discharge, because the surface of the eye is not the problem. The Mayo Clinic notes that anterior uveitis typically develops quickly, often over hours to a day or two, and usually in one eye at a time.

The urgency comes from what those inflammatory cells can do if left alone. Sticky protein can glue the iris to the lens, cells can clog the eye’s drainage channels and raise pressure, and repeated episodes can cloud the lens. Each of those is preventable with timely treatment, and each becomes harder to reverse the longer inflammation persists.

Ankylosing spondylitis eye pain: how uveitis usually announces itself

Ophthalmologists describe the anterior uveitis of spondyloarthritis as having a recognizable personality. It arrives fast, it prefers one eye, and it likes to alternate sides across different episodes. A person who had a flare in the left eye two years ago may find the right eye involved this time, with the left perfectly calm.

The typical experience is a dull ache that deepens over a day, a red eye that looks angrier close to the iris, marked discomfort in bright light, and vision that feels slightly fogged rather than sharply blurred. Watering is common; sticky discharge is not. Some people notice that the affected pupil looks smaller or that its shape has become slightly irregular. The NHS uveitis page lists these features and advises that anyone with them should be seen urgently rather than waiting for a routine appointment.

None of this is a checklist to work through at home. The point is narrower: eye pain in someone with ankylosing spondylitis should be assumed to be uveitis until an eye professional with a slit lamp has said otherwise. A slit lamp is the microscope-on-a-stand that lets the examiner see individual inflammatory cells floating in the front chamber, something no amount of mirror inspection can replicate.

It is also worth knowing that the first episode often comes before anyone has heard the words ankylosing spondylitis. Rheumatologists regularly meet patients whose journey began in an eye clinic, where an ophthalmologist noticed a pattern of recurrent iritis and asked about back pain and morning stiffness. If you have been told you have iritis and also have persistent low back pain that eases with movement, that combination is worth raising with your primary care clinician.

What eye disease is most commonly associated with ankylosing spondylitis?

Acute anterior uveitis is by a wide margin the most common eye disease linked to ankylosing spondylitis, and ankylosing spondylitis is one of the most common systemic conditions found when doctors look for a cause of recurrent anterior uveitis. The relationship runs in both directions, which is why eye and joint specialists so often share patients.

How common is it? The NHS describes uveitis as a frequent complication of the condition, and across large patient series the lifetime figure generally falls somewhere between a quarter and roughly 40% of people with ankylosing spondylitis. The spread reflects differences in how long patients were followed and how carefully mild episodes were recorded. What the studies agree on is that the risk persists throughout life rather than clustering in the first few years, so a person who has gone a decade without an episode has not aged out of the possibility.

Other eye problems occur but are far less typical. Scleritis, an inflammation of the tough white outer coat, is more characteristic of rheumatoid arthritis than of spondyloarthritis. Inflammation at the back of the eye is uncommon in ankylosing spondylitis and, when it appears, prompts doctors to consider related conditions such as inflammatory bowel disease or psoriatic arthritis, which sit in the same family of diseases and share the HLA-B27 link.

The Cleveland Clinic and Mayo Clinic both note that uveitis, whatever its cause, carries a risk of complications including glaucoma (raised eye pressure that damages the optic nerve), cataract (clouding of the lens), and macular edema (fluid swelling at the center of the retina). The encouraging half of that sentence is that in spondyloarthritis-related anterior uveitis these complications are much less likely when episodes are treated early and fully.

HLA-B27 and uveitis: can a gene actually cause an eye flare?

HLA-B27 is a version of a gene that helps the immune system display fragments of protein to T cells, the white blood cells that decide whether something is foreign. MedlinePlus Genetics notes that the large majority of people with ankylosing spondylitis carry HLA-B27, yet most people who carry it never develop the condition. It is best understood as a strong risk factor rather than a switch.

The same is true for the eye. HLA-B27 does not directly cause uveitis, but it makes the immune system more likely to mount an inflammatory response in certain tissues, and the front of the eye is one of them. Among people with acute anterior uveitis, HLA-B27 carriers are over-represented, and their episodes tend to follow the classic pattern described above: sudden, one-sided, alternating, and recurrent. People with uveitis who lack the gene more often have a different pattern, with both eyes involved at once or a slower, smoldering course.

Why the eye and the sacroiliac joints? Researchers have proposed several explanations. One is molecular mimicry, in which a protein fragment from a gut or urinary bacterium resembles a protein found in these tissues closely enough to confuse HLA-B27-restricted T cells. Another involves the way HLA-B27 molecules fold, which may trigger cellular stress signals that ramp up inflammatory chemicals such as interleukin-17 and tumor necrosis factor. Neither theory is settled, and the honest summary is that the mechanism is still being worked out.

Practically, knowing your HLA-B27 status rarely changes what happens when your eye becomes painful. The examination and the treatment are the same. Where it matters is in the background: it raises the pre-test probability for the clinician, helps explain a family history that includes both back pain and iritis, and is one piece of the puzzle when a diagnosis is still uncertain.

Why the eye can flare when the back feels fine

One of the most disorienting features of uveitis in ankylosing spondylitis is its independence. Patients often assume that a calm spine means a calm immune system, and then wake with a painful eye during their best stretch of back health in years. The reverse also happens: a severe spinal flare with no eye involvement at all.

The explanation lies in how differently the two tissues behave. Spinal inflammation in ankylosing spondylitis is a slow, grinding process at the places where ligaments and tendons attach to bone, and it tends to build over weeks. The front of the eye is a small, enclosed compartment with a special immune status: it normally suppresses inflammation to protect vision, and when that suppression fails, the response can be abrupt and self-contained. The Mayo Clinic describes anterior uveitis as coming on suddenly, in contrast to the gradual pattern of joint symptoms.

Treatment adds another layer. Many medicines that control spinal disease act on the whole body, but the eye is partly walled off by barriers that limit how much of a drug reaches it. That is why some people on effective treatment for their spine still experience eye episodes, and why an eye flare on treatment does not automatically mean the medicine has stopped working. It is also why ophthalmologists usually treat the eye directly, with drops, alongside whatever the rheumatologist is doing.

Triggers remain poorly understood. Some patients report episodes after infections, periods of exhaustion, or emotional stress; others find no pattern at all. The evidence for specific triggers is weak and mostly anecdotal, so the most reliable advice is not to hunt for a cause but to respond quickly when an episode begins.

Who is seen the same day, and who is usually asked to wait

Eye services triage constantly, and it helps to know where a painful eye in ankylosing spondylitis sits on their list. In most systems, a red, aching, light-sensitive eye in a person with a known spondyloarthritis or a history of iritis is treated as urgent and seen the same day or the next morning. The NHS advice for suspected uveitis is to seek an urgent appointment, and eye emergency departments and same-day clinics exist precisely for this category.

Who is seen fastest? Anyone with sudden vision change, a first-ever episode, pain that is escalating rapidly, or a history of complications such as raised pressure or adhesions during previous flares. Children and anyone whose eye pain came with a head injury, severe headache, or nausea are also prioritized, because those combinations raise other diagnoses. People who have had many episodes and hold a personalized plan agreed with their ophthalmologist may have a standing arrangement to start treatment early and be reviewed within a day or two.

Who is usually asked to wait, at least a little? Someone with mild grittiness, uniform redness, and discharge but no pain or light sensitivity is more likely to have conjunctivitis or dry eye, and a primary care clinician or optometrist may be the right first stop. Someone whose vision is unchanged and whose discomfort is clearly on the surface may be given a next-available appointment rather than a same-day one.

The important caveat is that triage is the clinic’s decision, not the patient’s. If you have ankylosing spondylitis and your eye hurts, describe your diagnosis and your symptoms honestly and let the service place you. Under-reporting to avoid being a bother is the single most common reason episodes are treated late.

How is uveitis in ankylosing spondylitis treated?

Treatment of an acute anterior uveitis episode aims at two things: switching off inflammation in the front chamber and preventing the iris from scarring to the lens. Both goals are usually achieved with eye drops, and the choice, frequency, and duration are set by the ophthalmologist based on what the slit lamp shows.

Corticosteroid drops are the mainstay. They reduce the leak of cells and protein from inflamed vessels, clearing the cloudy fluid and easing the ache. Because they can raise eye pressure in some people and thin the cornea with prolonged use, they are tapered gradually rather than stopped abruptly, and the eye is rechecked along the way. Dilating drops, sometimes called cycloplegics, relax the iris and ciliary muscles. That relieves the deep, cramping pain and, by holding the pupil open, keeps the inflamed iris from sticking to the lens behind it. A side effect is temporary blurring and light sensitivity, which usually eases as the drops are withdrawn.

When drops are not enough, an ophthalmologist may use a steroid injection around the eye or, less often, short courses of steroid tablets. For people with frequent recurrences, the conversation widens to include the rheumatologist. Certain biologic medicines that block tumor necrosis factor, a key inflammatory messenger in spondyloarthritis, are associated with fewer uveitis episodes, and current rheumatology guidance notes that not all medicines in this class perform equally on that measure. Whether to adjust systemic treatment because of the eye is a joint decision between the two specialists and the patient, weighing spinal disease, other health conditions, and personal preference.

What patients most want to know is how quickly the eye will feel better. The Mayo Clinic notes that anterior uveitis generally responds to treatment within days, with the full course of drops lasting weeks. Neither timeline is a guarantee; the eye sets the pace, and the review appointments exist to check it.

What the following days and weeks usually look like

The first 48 hours after starting treatment are often the most reassuring. Pain typically eases as the dilating drops release the iris spasm, and the sensitivity to light softens. Vision may actually feel worse before it feels better, because a dilated pupil lets in more light and cannot focus close up. Reading, screens, and driving can be difficult during this phase, and many people arrange a few days of lighter work or extra help.

Over the following one to two weeks, the redness fades and the cloudiness clears as the steroid drops do their work. The ophthalmologist usually rechecks the eye early on, then again as the drops are reduced. At these visits they count the inflammatory cells in the front chamber, measure eye pressure, and look for any adhesions. The taper matters: stopping steroids too soon is a common reason for a rebound flare, so the schedule is followed even when the eye looks and feels normal.

By four to eight weeks, most uncomplicated episodes have fully settled, a range consistent with the NHS description of acute anterior uveitis running its course over weeks with treatment. A small number of people experience a slower resolution or a second wave of inflammation during the taper, which extends the timeline and may prompt a different approach.

Between episodes, the eye is normal, and there is no lasting daily treatment for most people. Two habits help. One is knowing your own early warning signs well enough to act within hours rather than days next time. The other is keeping a brief record of each episode, which eye, how long, what treatment, so that the pattern is visible when the rheumatologist and ophthalmologist next compare notes about your overall plan.

Ankylosing spondylitis chest pain: when the ribs are the problem

Chest pain is unsettling in anyone, and ankylosing spondylitis makes it more likely for a mundane reason: the ribs are joints. Each rib meets the spine at the back and the breastbone at the front through small, cartilage-lined connections, and those attachment points are exactly the kind of tissue that spondyloarthritis inflames. Doctors call inflammation at the front junctions costochondritis, and inflammation at the back involves the costovertebral joints.

The resulting pain has a recognizable character. It is usually sharp or aching, sits along the rib margins or beside the breastbone, and is provoked by a deep breath, a cough, a sneeze, a twist, or pressing on the sore spot. It often follows the same pattern as spinal symptoms, worse after rest and easier with gentle movement. The Cleveland Clinic and Mayo Clinic both list chest and rib pain among the common sites of involvement in ankylosing spondylitis.

Over years, inflammation at these joints can stiffen the rib cage. People notice that a full breath does not expand the chest the way it used to and that the breathing effort shifts to the diaphragm. Clinicians measure this as reduced chest expansion, and it is one reason regular breathing exercises and posture work are built into ankylosing spondylitis physiotherapy. Reduced expansion rarely causes breathlessness on its own, but it does make the lungs less forgiving of infections and smoking.

The obvious difficulty is that chest wall pain and cardiac pain can feel similar to the person experiencing them. Position and movement are the most useful clues: pain that reliably worsens when you press the spot, twist, or take a deep breath leans toward the chest wall. Pain that comes on with exertion and eases with rest, or that arrives with breathlessness or sweating, does not, and should be treated as a possible heart problem until proven otherwise.

When chest symptoms point to the heart or lungs instead

Most chest discomfort in ankylosing spondylitis is musculoskeletal, but a minority of people develop involvement of the heart or lungs, and clinicians keep both in mind. The Mayo Clinic lists heart problems among the recognized complications, specifically inflammation of the aorta, the body’s largest artery, where it leaves the heart.

That inflammation, called aortitis, can stretch the ring supporting the aortic valve so that the valve no longer closes tightly. Blood then leaks backward with each beat, a condition called aortic regurgitation. Early on it is silent and picked up as a murmur or on an echocardiogram (an ultrasound of the heart). Later it can cause breathlessness on exertion, fatigue, or awareness of a forceful heartbeat. Inflammation near the valve can also affect the heart’s electrical wiring, producing slow rhythms or blocks that show up as dizziness, faintness, or unexplained tiredness.

Ankylosing spondylitis is also associated with a higher long-term risk of atherosclerotic heart disease than in the general population, a pattern seen across chronic inflammatory conditions. Inflammation appears to accelerate the process that narrows coronary arteries, and long-term use of anti-inflammatory painkillers may contribute in some people. This is why rheumatology guidance encourages attention to blood pressure, cholesterol, smoking, and physical activity as part of routine care, and why classic exertional chest pain in someone with ankylosing spondylitis deserves the same urgent cardiac assessment it would in anyone else.

The lungs are affected less often. A small proportion of people with long-standing disease develop scarring at the top of the lungs, and the stiff rib cage described earlier can make chest infections harder to shift. Breathlessness that is new, progressive, or out of proportion to activity is a reason for review, not something to attribute to the ribs by default.

Which AS symptoms need a same-day check? A quick comparison

Deciding how quickly to act is easier when the common scenarios are laid side by side. The table below is a guide to typical urgency, drawn from NHS and Mayo Clinic advice; the service you contact will make its own assessment.

What you notice	Most likely explanation	Typical urgency	Usual first contact
One painful, red, light-sensitive eye, mild blur	Acute anterior uveitis	Same day	Eye emergency service or urgent eye clinic
Sudden loss of vision or a curtain across sight	Several possibilities, some sight-threatening	Emergency	Emergency department
Gritty, uniformly red eye with discharge, no pain	Conjunctivitis or dry eye	Next available	Primary care or optometrist
Sharp rib or breastbone pain worse on pressing or twisting	Costochondritis or rib-joint inflammation	Routine review	Rheumatology or primary care
Chest pressure with exertion, breathlessness, sweating, or pain spreading to arm or jaw	Possible cardiac event	Emergency	Emergency services
New breathlessness, fainting, or a very slow pulse	Possible valve or rhythm involvement	Prompt, within days	Primary care for cardiac assessment

Two patterns in the table deserve emphasis. Eye symptoms almost always belong in the top two rows, because the cost of a false alarm is a short clinic visit while the cost of a missed episode can be permanent. Chest symptoms split more evenly, and the deciding features are exertion, breathlessness, and spread of pain rather than the location alone.

When in doubt about either, err toward the faster row. Emergency and urgent services would rather see a rib strain than miss a heart attack, and eye clinics would rather clear a conjunctivitis than treat a late uveitis.

What people often get wrong about ankylosing spondylitis eye pain and uveitis

The first myth is that a red eye can be watched for a few days to see whether it settles. For conjunctivitis that is reasonable; for uveitis it is how adhesions and pressure problems begin. The pattern of pain, light sensitivity, and redness concentrated near the iris should shortcut the waiting period.

The second is that over-the-counter redness-relief drops are a sensible first step. They constrict surface vessels and can mask redness without touching inflammation in the front chamber. They also make the eye harder to assess when you do arrive at the clinic. Lubricating drops are harmless but will not help; nothing sold without prescription treats uveitis.

Third, many people believe that a well-controlled spine means a well-controlled eye. The two flare independently, and an eye episode during good spinal control is not proof that the systemic treatment has failed.

Fourth is the assumption that HLA-B27 is destiny, either that carrying it guarantees eye disease or that lacking it rules uveitis out. Neither is true. MedlinePlus Genetics is clear that most carriers never develop ankylosing spondylitis, and uveitis occurs in people without the gene.

Fifth, some patients stop steroid drops the moment the eye feels normal. The taper exists because inflammation can persist at a level you cannot feel, and early stopping is a recognized cause of rebound. The schedule is a clinical instruction, not a suggestion.

Sixth, chest pain is often dismissed as ribs because ribs have hurt before. Previous costochondritis does not immunize anyone against heart disease, and ankylosing spondylitis carries a higher cardiovascular risk, not a lower one.

Finally, there is a belief that uveitis inevitably damages vision over time. With prompt treatment of each episode, most people with spondyloarthritis-related anterior uveitis keep good long-term sight. The risk is real, but it is largely a risk of delay.

Questions to ask your care team

Good questions turn a rushed appointment into a plan. These are the ones eye and rheumatology clinicians most often wish patients had asked.

• If my eye becomes painful and red, exactly where should I go, and does that change at night or on weekends?
• Do I have a written plan for a suspected uveitis episode, and is there anything I am allowed to do before I am seen?
• Has my eye pressure or lens been affected by previous episodes, and does that change how quickly I should act next time?
• How many episodes in what period would prompt you to reconsider my systemic treatment, and who makes that decision?
• Do my rheumatologist and ophthalmologist share letters, and can I ask for a summary after each eye episode?
• What features of chest pain would you want me to treat as an emergency rather than as rib inflammation?
• Have I had an assessment of my heart, such as a listen for murmurs or an echocardiogram, and how often should that be repeated?
• Which of my cardiovascular risk factors, blood pressure, cholesterol, smoking, activity, would you prioritize?
• Are there breathing or posture exercises that help maintain chest expansion, and who can teach them?
• If I develop symptoms while traveling, what information should I carry to help an unfamiliar clinician understand my history?

Bring a short list of previous eye episodes with dates approximated to the month, which eye was involved, and how long treatment lasted. Bring your current medicine list, including anything bought without prescription. Ask for the name of the person to contact if things change between appointments. None of these questions is a challenge to your team; they are the questions your team would ask if the roles were reversed.

When to call your doctor

Some situations should not wait for a routine appointment, and it helps to have them clear in your mind before they happen.

Seek an urgent same-day eye assessment for any new eye pain with redness or sensitivity to light, especially if the redness is concentrated around the colored part of the eye, if your vision has become blurred or cloudy, if one pupil looks smaller or irregular, or if you have had uveitis before and recognize the early feeling. Go to an emergency department for sudden loss of vision, a shadow or curtain across part of your sight, severe eye pain with nausea or vomiting, or eye symptoms following a blow to the head or face.

Call emergency services immediately for chest pain or pressure that comes on with exertion or at rest and does not ease within a few minutes, chest pain accompanied by breathlessness, sweating, nausea, or pain spreading to the arm, neck, or jaw, or a sudden faint or collapse. Ankylosing spondylitis raises rather than lowers the odds that chest pain is cardiac, so previous rib pain should not delay the call.

Contact your rheumatology team or primary care clinician within days for new or worsening breathlessness, palpitations, dizziness or near-fainting, a noticeably slow pulse, rib pain that is not behaving like your usual flare, fever alongside a flare, or any eye symptom that is improving more slowly than your ophthalmologist predicted.

Between those situations lies the ordinary work of living with a chronic condition, and that is where your treating team belongs. Every decision about investigating a symptom, adjusting a medicine, or changing a plan rests with them and with you, informed by the specifics of your case that no article can know. The purpose of this guide is to make sure the conversation starts in time.

Frequently asked questions

What autoimmune condition is linked to uveitis?

Ankylosing spondylitis and the wider spondyloarthritis family are among the conditions most frequently linked to anterior uveitis. Others include reactive arthritis, psoriatic arthritis, inflammatory bowel disease, juvenile idiopathic arthritis, sarcoidosis, and Behçet disease. Many of these share the HLA-B27 gene variant. When an ophthalmologist diagnoses recurrent uveitis, asking about back pain, skin, and bowel symptoms is standard practice because the eye is often the first sign.

What eye disease is most commonly associated with ankylosing spondylitis?

Acute anterior uveitis, also called iritis, is by far the most common. It inflames the iris and ciliary body at the front of the eye, causing pain, redness, light sensitivity, and blurred vision, usually in one eye. The NHS describes it as a frequent complication of ankylosing spondylitis, and large patient series place the lifetime risk between roughly a quarter and 40% of people with the condition.

Can HLA-B27 cause uveitis?

HLA-B27 does not directly cause uveitis, but it substantially raises the risk. The gene variant alters how immune cells recognize protein fragments, making inflammation more likely in certain tissues including the front of the eye. HLA-B27-positive uveitis tends to be sudden, one-sided, and recurrent. Most people who carry HLA-B27 never develop either uveitis or ankylosing spondylitis, and uveitis also occurs in people without the gene.

What are the anterior uveitis symptoms people with ankylosing spondylitis should recognize?

The typical experience is a deep ache in one eye that builds over hours to a day, marked discomfort in bright light, redness that is strongest close to the colored part of the eye, watering, and a foggy quality to vision. The affected pupil may look smaller. Discharge is unusual. Any of these features in someone with ankylosing spondylitis should prompt a same-day eye examination rather than a wait-and-see approach.

Is iritis and ankylosing spondylitis the same as uveitis?

Iritis is a type of uveitis. Uveitis is the general term for inflammation of the eye’s middle layer, and iritis refers specifically to inflammation of the iris at the front. Because ankylosing spondylitis almost always affects the front of the eye, doctors often use iritis, anterior uveitis, and uveitis interchangeably when discussing the condition. The examination, treatment, and urgency are the same whichever term is used.

What are the worst symptoms of ankylosing spondylitis?

For most people the most disruptive symptom is inflammatory back and buttock pain with prolonged morning stiffness that eases with movement. The complications that clinicians worry about most are sight-threatening uveitis if treated late, spinal fractures in a stiffened spine after falls, and heart involvement such as aortic valve leakage or rhythm disturbance. Fatigue is frequently reported as the symptom that most affects daily life. Severity varies widely between individuals.

Why does ankylosing spondylitis cause chest pain?

The ribs connect to the spine and breastbone through small cartilage-lined joints, and ankylosing spondylitis inflames exactly this kind of attachment tissue. The result is costochondritis or costovertebral joint inflammation, felt as sharp or aching pain that worsens with deep breathing, coughing, twisting, or pressing on the area. Over time the rib cage can stiffen, reducing chest expansion. Exertional chest pain with breathlessness or sweating needs urgent cardiac assessment instead.

How long does a uveitis flare last with treatment?

Pain and light sensitivity typically ease within days of starting steroid and dilating drops, and most uncomplicated episodes of acute anterior uveitis settle fully over several weeks as the drops are gradually tapered, a timeline consistent with NHS and Mayo Clinic descriptions. Some episodes take longer or rebound during the taper, which is why review appointments continue until the ophthalmologist confirms the front chamber is clear.

Can ankylosing spondylitis eye problems cause blindness?

Untreated or repeatedly delayed uveitis can permanently damage sight through raised eye pressure, cataract, adhesions between the iris and lens, or swelling at the center of the retina. With prompt treatment of each episode, most people with spondyloarthritis-related anterior uveitis maintain good long-term vision. The risk is largely a risk of delay, which is why a painful red eye in ankylosing spondylitis is treated as urgent.

Does treating the spine also prevent uveitis?

Sometimes, but not reliably. The eye is partly separated from the bloodstream by barriers that limit how much of a systemic medicine reaches it, so people on effective spinal treatment can still have eye episodes. Certain biologic medicines that block tumor necrosis factor are associated with fewer recurrences, and not all perform equally on this measure. Whether to adjust treatment because of the eye is a decision for the rheumatologist and ophthalmologist together.
