A Study was conducted to compare changes in retinal microvasculature of young and elderly patients with retinal vein occlusion (RVO) after anti-VEGF treatment.

Patients with RVO who received anti-VEGF care were assessed retrospectively and divided into two categories based on their age. During each visit, OCT angiography images were obtained. The best corrected visual acuity (BCVA), vessel density (VD), and foveal avascular zone (FAZ) of the two groups were measured and compared. Improvements in vision is linked to changes in the retinal microvasculature.

Results:
--20 patients with 20 eyes were enrolled in the younger group and 46 patients with 46 eyes were enrolled in the older group.

--Younger patients demonstrated better BCVA, higher VD and smaller FAZ than older patients at 12 months after the first anti-VEGF treatment.

--The improvement of VD was observed only in the younger group.

--A positive correlation between vision improvement and VD increase was noted.

Finally, young patients with RVO will have their deep retinal vasculature quickly rehabilitated, resulting in a better visual outcome.
