[Arteriolar constriction in the treatment of branch retinal vein occlusion. Initial experience]

The authors describe their first experiences in the treatment of 12 eyes with prognostically unfavourable occlusion of the retinal branch of the vein by application of the laser technique of arteriolar constriction. They introduced photocoagulation 1 to 4 weeks after the onset of the occlusion. The resulting visual acuity 6/12 and better was achieved in 83%, the worst resulting acuity 6/18 in 17% two years after onset of the occlusion. In all the eyes, the achieved improvement was approximately by 4 lines of Snellens optotypes.
