Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The ATORVO study is designed to determine whether atorvastatin (Lipitor) can improve vision, when compared to placebo

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Retinal vein occlusion (RVO), a common cause of visual loss in the Western world, is a disease whose etiology resembles that of classic atherosclerosis. A therapy that lowers the risk of arterial and venous thrombosis would seem to be a reasonable approach to managing this disease, for which there is currently no treatment.

ATORVO is a randomized double-masked clinical trial comparing a daily dose of 80 mg of atorvastatin to matched placebo in persons recently diagnosed with RVO. At 24 weeks after randomization, we will evaluate each participant's visual acuity and the presence of secondary complications related to RVO.
