Results
Microaneurysms formed in collateral vessels caused persistent macular edema. Retinal laser photocoagulation targeting the microaneurysms in collateral vessels was effective to reduce macular edema and additional treatments in patients with BRVO.

Other related information
Direct laser at collateral vessels might occlude the collateral vessels, resulting in worsening of macular edema because collateral vessels play an important role on resolution of congested blood flow.
