Treatment of Retinal Vein Occlusion

Retinal Vein Occlusion is a condition in which the vein bringing blood back from the eye is blocked, causing a build up fluid in the eye, specifically in and around the retina. This fluid build up causes rapid and usually permanent loss of vision.

Central Retinal Vein Occlusion

A new research study looked at patients with retinal vein occlusion over a five year period. Patients received standard treatment of anti vascular endothelial growth factor (anti-VEGF) injections over the monitored five year period, either with drug brand Avastin or the Eylea brand. They found that after the first six months, patients had improved visual acuity, being able to read on average 3+ lines more on an eye chart. Researchers noticed that these monthly injections of the anti-VEGF were reduced at the discretion of the patient's physician. With these changes, visual acuity decreased slightly at the five year mark,

This study is important because it was previously unknown that anti-VEGF injections needed to be continued for a long period of time in order to sustain visual acuity and prevent vision loss in patients with retinal vein occlusion. Additionally, this study showed that retinal vein occlusion is a chronic disease rather than an acute disease, due to the lasting symptoms. These findings can help physicians make more informed and patient oriented decisions when treating a patient with retinal vein occlusion.
