Rethinking strategies for the treatment of branch retinal vein occlusion and secondary macular edema / 中华眼底病杂志

ABSTRACT

Pharmaceutical therapy,including anti-vascular endothelial growth factor treatment and intravitreal corticosteroids,is the most common treatment for branch retinal vein occlusion (BRVO) and its complications,however there are confusing ideas about the protocol,patient selection,timing and endpoint of this treatment.The disease is easy to relapse with these drugs therapy.Collateral vessel formation was found in patients receiving intravitreal injection of ranibizumab or triamcinolone for BRVO and secondary macular edema.The mechanism of collateral vessel formation has not been carefully investigated.In the past thrombolysis,arteriovenous fasciostomy and laser choroidal retinal vascular anastomosis were used to reconstruct the retinal circulation,but their rationality,effectiveness and safety need to be further were studied.In recent years,because of the key technology is still immature,the artificial vascular bypass surgery experiment is not yet practical,but provides us a new idea worth looking forward to for the treatment of BRVO.
