Modern concept in pathophysiology and therapy of branch retinal vein occlusion

Aims: to evaluate the effects of laser arteriolar constriction technique (LACT) in the treatment of branch retinal vein occlusion (BRVO). Methods: We performed photocoagulation treatment in 82 eyes with BRVO. We used our own modification of LACT, which consists in the application of coalesent coagulation spots through the afferent arteriole. As an early treatment we consider such a photoagulation which is performed within 2 months after the onset of occlusion. The patients were divided into two basic groups: group A – early laser treatment and group B – laser treatment was initiated later than 2 months after the…
