[Reversible star formation of the macula in retinal angiomatosis].

Case report concerning a young man in whom exudative retinitis had occurred as a result of the A-V shunt of a retinal angioma, leading to sudden loss of vision. With argon laser and xenon arc photocoagulation a minor hemorrhage cleared up spontaneously, the retina remained attached and vision increased to 20/25 within 1 year. The authors believe that the combined photocoagulation insured an interruption of blood flow in feeder vessels and the breakdown of the intervening capillary bed.
