Overview
The purpose of this study is to evaluate the overall treatment characteristics and efficacy of Aflibercept in the treatment of PCV in China through a multicenter, observational, prospective-retrospective study. This study is a long-term follow-up cohort, plans to unite a total of 30 hospitals in different regions of the China to enroll 1000 PCV patients.
Main evaluation indicators: To observe the changes in visual acuity (BCVA) in PCV patients treated with Aflibercept to evaluate the effectiveness of the treatment.
Description
Primary Study Objective(s) To provide overall treatment characteristics of aflibercept in PCV treatment Secondary Study Objective(s)
- To describe the treatment regimens of aflibercept treatment on PCV in clinical practice.
- To evaluate effectiveness of aflibercept treatment on PCV including vision gain (BCVA) and anatomic improvement (CRT, Polyps regression, Polyps inactivity, and PED)
- To explore the relative factors of aflibercept treatment effectiveness.
- To describe patients' tolerance to anti-VEGF and PDT treatment.
- To collect safety information with aflibercept treatment in a wider population setting
