To evaluate the incidence, characteristics, and results of treatment of choroidal neovascularization (CNV) in myopic eyes corrected by photorefractive keratectomy (PRK).
University Miguel Hernández, Instituto Oftalmológico de Alicante, Alicante, Spain.
This study was of the incidence of CNV in 5936 consecutive eyes that had PRK for the correction of myopia. Mean follow-up was 38.5 months +/- 17.4 (SD).
Extrafoveal CNV developed in the right eye of a 44-year-old woman 26 months after PRK for the correction of -12.00 diopters (D) of myopia. The follow-up after PRK was 38 months. Best corrected visual acuity (BCVA) before PRK was 20/40 (spherical equivalent [SE] -12.00 D). After PRK, BCVA was 20/32 SE -1.75 D). The CNV was treated by direct argon-green laser photocoagulation and did not recur in the subsequent 12 months). After CNV treatment, BCVA was 20/32 (SE -2.25 D).
The incidence of CNV after PRK for myopia was low. Choroidal neovascularization is a possible complication in myopic eyes, and the risk exists before PRK. After PRK, the risk of CNV in myopic patients did not increase.
评估经准分子激光原位角膜磨镶术（PRK）矫正近视的眼中脉络膜新生血管（CNV）的发生率、特征及治疗结果。

本研究纳入了5936只连续接受PRK矫正近视的眼睛，以评估CNV的发生率。平均随访时间为38.5个月±17.4（标准差）。
一名44岁女性在接受PRK矫正-12.00屈光度（D）近视26个月后，右眼出现了黄斑外CNV。PRK术后随访38个月。PRK术前最佳矫正视力（BCVA）为20/40（等效球镜度[SE]-12.00 D）。PRK术后，BCVA为20/32（SE -1.75 D）。该CNV通过氩绿激光直接光凝治疗，在随后12个月内未复发。CNV治疗后，BCVA为20/32（SE -2.25 D）。
PRK矫正近视后CNV的发生率较低。脉络膜新生血管是近视眼中一种可能的并发症，且在PRK术前就存在风险。PRK术后，近视患者发生CNV的风险并未增加。
