Ultra-wide-field Fluorescein Angiography in Patients With Macular Edema Secondary to Retinal Vein Occlusion
This study mainly observed the ischemic index and vascular leakage index changes on ultra-wide field fluorescence angiography after anti-VEGF treatment , and whether these changes correlated with treatment efficacy in patients with macular edema secondary to retinal vein occlusion.
• Male or female aged 18 years or older
• Macular edema secondary to CRVO,BRVO or HRVO
• Duration of RVO not more than 4 months
• Naïve patients. Patient with previous RVO (more than 12 months before the inclusion date) completely resolved (normalization of visual acuity and fundus examination) and who have experienced a recurrence of RVO are also considered naive
• Patient who agrees to participate in the study and who has given his/her written, informed consent
