Trial Outcomes & Findings for Vascular Endothelial Growth Factor (VEGF) Levels in Retinal Vein Occlusion (RVO) During Anti-VEGF Treatment (NCT NCT04707625)
NCT ID: NCT04707625
Last Updated: 2025-02-24
Results Overview
Measured by central retinal thickness using optical coherence tomography - OCT is an imaging method used to generate a picture of the back of the eye, called the retina. The picture is made by precisely measuring the amount of a dim red light that reflects off the retina
TERMINATED
PHASE4
17 participants
Baseline through week 35

Participant Flow
Participants were inappropriately enrolled; IRB required early termination due to the number of protocol violations.

| Measure |
Aflibercept
All subjects will receive aflibercept every 4 weeks. Once vascular endothelial growth factor levels become normal and macular edema improves treatment windows will be extended up to every 12 weeks.

Using Snellen Visual Acuity charts - The results are based on what line the patient can read with ease - If a subject's visual acuity is so poor that the subject can't see any letters on the charts, finger counting and/or hand motions will be checked
