Choroidal neovascularization following photorefractive keratectomy

Purpose to describe a case of choroidal neovascularization (cnv) following photorefractive keratectomy (prk) to correct myopia. methods we performed prk in both eyes of a 20-year-old girl to correct myopia. refractive error was −4.75 −2.25 × 5 in the right eye and −5.00 −1.25 × 180 in the left eye. metamorphopsia was noticed by the patient in the right eye one month after the surgical procedure. the patient was referred 3 months later when visual loss happened. results fluorescein angiography and optical coherence tomography (oct) were performed which were compatible with cnv. after three monthly intravitreal bevacizumab injections,sub-retinal hemorrhage and intraretinal fluid resolved,but subretinal scar remained without any visual acuity improvement. conclusions it seems that cnv may occur after prk in myopic eyes. also,refractive surgeons should consider cnv development in cases with visual compliant or metamorphopsia following prk. © 2016 iranian society of ophthalmology
