[Coats syndrome in retinitis pigmentosa. Clinical aspects and therapeutic possibilities].

Coats disease itself is a rather rare condition, whereas Coats syndrome has been observed in about 1.2-4.9% of all retinitis pigmentosa (RP) patients.

[Bilateral choroid osteoma].

Background: Choroidal Osteoma is a rare, typically monolateral benign ossifying tumor of the choroid found in healthy females aged 10 to 30 years. In contrast, multiple idiopathic sclerochoroidal calcifications occur in elderly otherwise healthy subjects. Local or generalized distortions of calcium phosphate metabolism may cause secondary choroidal calcifications.

Panretinal photocoagulation in diabetic retinopathy: argon versus dye laser coagulation.

The range of wavelengths used in ophthalmic photocoagulation treatment has been greatly enlarged by the development of the dye laser. To investigate the efficacy and possible side effects of orange dye laser light in the treatment of diabetic retinopathy, we performed a prospective, controlled clinical study comparing argon blue-green and orange dye laser light. In 14 patients with diabetic retinopathy of equal severity in both eyes one eye was randomly assigned to either blue-green argon (488 and 514.
