Extended Follow-up of Patients With Macular Edema Due to Retinal Vein Occlusion (RETAIN)
2013年11月27日 更新者：Peter A Campochiaro, MD
Extended Follow-up of Patients With Macular Edema Due to bRanch rETinal Vein Occlusion (BRVO) or centrAl Retinal veIn occlusioN (CRVO) Previously Treated With Intravitreal Ranibizumab
This study evaluates long-term safety in patients with macular edema due to Retinal Vein Occlusion (RVO) originally enrolled in the BRAVO & CRUISE trials and subsequently followed in the HORIZON extension trial.
研究概览
详细说明
There is strong evidence that ranibizumab provides benefit in subjects with macular edema due to RVO; however, some subjects required continued injections for years to maintain those benefits.
It is likely that such subjects have continued production of VEGF (Vascular Endothelial Growth Factor) from areas of nonperfused retina in the periphery.
One strategy is to perform scatter photocoagulation to areas of nonperfusion to reduce continued production of VEGF, but it is important to know if visual benefits are maintained when this is done, because if it is not, it would be better to continue intermittent injections of ranibizumab.

Mean Changes in Visual Acuity
大体时间：24 mos from study baseline
|
Mean changes in visual acuity.
Visual acuity is measured using standard ETDRS (Early Treatment Diabetic Retinopathy Study) charts which measure visual acuity in terms of letters( ETDRS Letters) read at a distance of 4 meters away from the chart.
The ETDRS letters Score can be from 0 to 100, with 0 representing poor vision and 100 representing best vision.
