[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.

[Case report of a choroidal osteoma].

Choroidal osteoma caused blurred vision in a 45-year-old man. Ophthalmoscopy showed a characteristic tumor with irregular elevation and of a yellowish color with a vascular network on the surface. Ultrasonic A-scan findings, hyperfluorescence in angiograms and visibility on computer tomograms confirmed the diagnosis, even though the patient's age and sex, and the location of the tumor, were unusual.
