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, - 2.25x5 in the right eye and -5.00, -1.25x180 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 andintraretinal fluid resolved, but subretinal scar remained without any visual acuity improvement. Conclusion: 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
