Large Juxtafoveal Telangiectasia

A 22-year-old male university student was referred due to gradual visual loss in his left eye since one year ago. His past medical and ocular history were unremarkable. On ophthalmological examination, best corrected visual acuity was 20/20 and 20/80 in the right and left eyes respectively. Anterior segment examination was unremarkable and intraocular pressure was within normal limits in both eyes. On funduscopic examination of the left eye, diffuse parafoveal telangiectatic vessels were evident temporal to the fovea. Multiple saccular aneurysms surrounded the lesion, but no exudation was apparent (Fig. 1). Fluorescein angiography delineated the true extent of the lesion and demonstrated some degree of leakage (Figures 2, 3). Retinal thickening temporal to the fovea was present on optical coherence tomography (OCT) (Fig. 4). The patient was followed conservatively for a while before his vision declined to 20/160. Because of the progressive nature of the disease and decrease in visual acuity during the follow-up period, 1.25 mg bevacizumab
