Macular Edema, Retinal Vein Occlusion
Conditions
Keywords
Ultra-wide field fundus fluorescein angiography, ischemic index, leakage index
Brief summary
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.
Detailed description
Ultra-wide field fluorescence angiography can clearly observe the peripheral retina. This study mainly observes the ischemic index and vascular leakage index changes on UWFA after anti-VEGF treatment and evaluates these changes associated with treatment efficacy in patients with macular edema secondary to retinal vein occlusion.
Interventions
Intravitreal injection of Ranibizumab 0.5 MG/0.05 ML
Ultra-wide-field Fluorescein Angiography can clearly observe the peripheral retina

Patient with another retinal disease in the study eye: diabetic retinopathy, maculopathy of any cause (age-related macular degeneration, epimacular membrane, myopia, etc) responsible for decreased vision, advanced glaucoma, cataract severely affecting vision and/or requiring surgical treatment during the 24 months study period 2. Active or suspected ocular or periocular infection 3. Active severe intraocular inflammation 4. RVO complicated with neovascularization 5. Patient who has previously undergone laser panretinal photocoagulation, grid-laser or photodynamic therapy, any anti-VEGF or corticoids intravitreal injections in the study eye 6. Patient already included in the study for the treatment of the fellow eye 7. Pregnant or breastfeeding woman 8. Lack of effective contraception for women of childbearing age 9. Patient taking part in an interventional study
