Summary

Central retinal vein occlusion (CRVO) occurs when the main blood vessel that transports blood away from the retina (the very back portion of the eye) becomes blocked, causing the leakage of fluid into the retina and thereby causing a swelling of the macula (the portion of the retina responsible for fine vision). This swelling is called macular edema. When the macula swells with fluid, central vision becomes blurry. The study drug aflibercept has been shown to reduce the amount of fluid and blood leaked into the retina. It can help to stabilize, and in many cases, improve the vision loss related to CRVO. Aflibercept has been approved for the treatment of macular edema secondary to CRVO in the United States (US), European Union (EU), Japan, and other countries.

The study was considered research because, although the study drug was already on the market for macular edema secondary to CRVO, there were no studies available that addressed the questions of what were useful intervals for treating and assessing patients, how did they differ among patients, and how were criteria applied for retreatment. The purpose of this study was to evaluate the effectiveness, treatment interval, and safety of the treatment regimen (pattern for administering treatment) in subjects with macular edema secondary to CRVO. In addition, this study explored new imaging methods for assessing the affected eye.

Conditions

  • Central Retinal Vein Occlusion

Interventions

DRUG

Aflibercept (Eylea, BAY86-5321)

The recommended dose for intravitreal aflibercept was 2 mg equivalent to 50 μL. Study treatment was administered at baseline and at monthly intervals until stabilization of disease. When stability was achieved, the treatment interval could be extended based on visual and anatomic outcomes as judged by the treating investigator.
