Trial Summary

What is the purpose of this trial?This trial is testing a higher dose of an eye injection called aflibercept in people with vision problems due to retinal vein occlusion. The goal is to see if a higher dose can be given less frequently while still helping to improve vision. The treatment works by blocking a protein that causes swelling in the eye. Researchers will compare vision improvements and safety between different doses. Aflibercept has been used to treat macular edema secondary to retinal vein occlusion and has shown efficacy in various studies.

Eligibility Criteria

This trial is for adults over 18 with macular edema due to a blocked retinal vein, diagnosed within the past 16 weeks. They must have specific vision acuity and central swelling thickness, be treatment-naive, and agree to use effective contraception. Exclusions include uncontrolled diabetes, recent stroke or heart attack, other eye diseases affecting vision, previous certain treatments or surgeries for RVO in the affected eye.

Inclusion Criteria

Your eye has a certain level of fluid buildup, as confirmed by special eye scans.

I can sign the consent form myself or have someone legally allowed to do it for me.

Your vision score is between 73 and 24 on a special eye test in the eye being studied.

Participant Groups

The study tests whether a higher dose (8 mg) of aflibercept injected into the eye is more effective and safer than the standard dose (2 mg) for treating macular edema caused by retinal vein occlusion. The main goal is to see if there's an improvement in visual acuity after 36 weeks compared to standard care.
