목적 : To investigate the prevalence of polypoidal choroidal vasculopathy (PCV) in patients with myopic choroidal neovascularization (CNV) using indocyanine green angiography (ICGA).
방법 : A total 297 eyes (255 patients) who presented with treatment-naive myopic CNV between January 2005 and December 2011 at Yonsei University Medical Center were retrospectively reviewed. Fluorescein angiography (FA) images obtained from the patients were analyzed to detect CNV presence and classify disease type. ICGA images were reviewed to detect polypoidal lesions. Main outcome measure was the prevalence of polypoidal lesions in patients with myopic CNV.
결과 : All 297 eyes with myopic CNV were type 2 CNV, and mean age at diagnosis was 47.32±14.69 years. Mean refractive error was -11.95±5.88 diopters and mean axial length was 29.39±2.02 mm in the affected eyes. 141 eyes were of age older than 50 years (mean 60.48±7.34 years). No eyes with myopic CNV showed polypoidal lesions on ICG angiography at initial presentation. After treatments, 243 eyes completed at least 12 months of follow-up, and 86 eyes (35.4%) showed at least one recurrence during follow-up. Follow-up FA, and ICGA showed no polypoidal lesions associated with recurred myopic CNV.
결론 : ICGA analysis demonstrated no polypoidal component in myopic CNV eyes.
