Long term visual outcome after arteriolar constriction in patients with branch retinal vein occlusion

Aim. To evaluate the final best corrected visual acuity (BCVA) in patients with branch retinal vein occlusion (BRVO) treated with either (1) laser arteriolar constriction (ACo) or (2) the standard treatment recommended by the Branch Vein Occlusion Study Group (grid laser photocoagulation (GLP) or only observation (if indication criteria for GLP were not met). Methods. 358 BRVOs were treated in three different ways: early ACo (n=133) performed /= 0.4. Results. Based on the proportion of 1 year BCVA /= 0.4. Conclusions. Early ACo significantly reduces the prevalence of a final BCVA
