Fundus fluorescein angiography (FFA) in branch retinal vein occlusion (BRVO) involving the superotemporal vein shows all of the following EXCEPT:

• A Delayed filling of the affected venous segment
• B Capillary non-perfusion areas in the watershed zone
• C Disc hyperfluorescence from optic nerve head new vessels ✓
• D Leakage of dye at the arteriovenous crossing point

Explanation

In BRVO, FFA shows delayed and irregular filling of the obstructed vein, areas of capillary non-perfusion, collateral vessel formation, and leakage at the site of AV crossing. Disc neovascularization (NVD) and associated disc hyperfluorescence are features of central retinal vein occlusion (CRVO) or proliferative diabetic retinopathy, not typically of BRVO unless macular or peripheral NVE is present.
