[Macular involvement in angioid streaks. Gronblad-Strandberg syndrome]

Between 1971 and 1988, we examined 116 eyes of 58 patients with Gronblad-Strandberg syndrome in private practice and in the Retinal Department of the Eye Clinic, Faculty of Medicine, Ankara University. There was initial macular involvement in 79% of cases with angioid streaks. The most frequently encountered lesion, found in 53% of the cases, was choroidal neovascularization. Macular involvement had become bilateral in 80% of the cases after 12.5 months median follow up. Thirteen of the 50 eyes with choroidal neovascularization were treated by argon or red krypton laser photocoagulation. Vision decreased during follow-up in 15% of the 13 eyes treated whereas it decreased in 32% of the 69 eyes unsuitable for laser treatment.
