Brief Summary

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

To investigate the efficacy of laser photocoagulation combined with ranibizumab intravitreal injection in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) in long term.

Detailed Description

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

To investigate the efficacy of ranibizumab intravitreal injections-driven by achieving vision acuity stabilization compared to combination with laser photocoagulation in Chinese patients with visual impairment in ME due to BRVO.

The result of the trial will be used to support new therapy in the BRVO in China.
