Clinical focus

The areas of expertise listed for Dr. Guleser cover a range of retinal, uveal and ocular surface conditions. On the retinal side, these include acute idiopathic maculopathy, bacillary layer detachment, choroidal flow insufficiency, paracentral acute middle maculopathy and acute macular neuroretinopathy. He also lists Behçet’s uveitis, pseudoexfoliation syndrome, tear film dysfunction and open globe injuries among his fields of interest.

A further focus is ocular oncology, in particular intraocular tumors and uveal melanoma. The procedures and techniques listed in his profile are optical coherence tomography angiography, a non-invasive imaging method used to assess retinal and tumor vasculature, together with iodine-125 plaque brachytherapy and gamma knife stereotactic radiosurgery, two radiation-based approaches used in the management of uveal melanoma.
