Etiologies and Characteristics of Choroidal Neovascularization in Young Chinese Patients

摘要

Purpose: To investigate the etiologies and characteristics of choroidal neovascularization (CNV) in young Chinese patients. Methods: A retrospective review of young Chinese patients (50 years of age) with CNV from January 2010 to June 2016 was performed. Results: Of the 501 patients (537 eyes) with CNV, 58.7% were female, and 7.2% had bilateral CNV. The mean age was 35 years. The etiologies were idiopathic CNV (ICNV, 43.9%), pathologic myopia (PM, 21.9%), punctate inner choroidopathy (PIC, 17.4%), polypoidal choroidal vasculopathy (4.4%), multifocal choroiditis with panuveitis (3.6%), and other disorders (8.8%). Five hundred and six CNVs (94.2%) showed a predominantly classic CNV composition on fundus fluorescein angiography (FFA) and 316 CNVs (96.6%) were type 2 CNV on optical coherence tomography (OCT). Conclusion: The etiologies of CNV in young Chinese patients were diverse, and ICNV, PM, and PIC were the three most common etiologies. Most CNVs were classic on FFA and type 2 on OCT. (C) 2018 S.
