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.
