The Treatment of Serous Macular Detachment Secondary Choroidal Melanomas and Nevi

Abstract

The authors successfully treated with laser photocoagulation five patients who had a serous macular detachment secondary to leakage from a pigmented choroidal tumor. Three patients had dye leakage on fluorescein angiography from a choroidal neovascular membrane. The subretinal fluid resolved in all three patients after the neovascular membrane was obliterated by either krypton red (2 patients) or argon green (1 patient) laser photocoagulation. The other two patients had prominent leakage from a localized choroidal neovascular membrane as well as mild diffuse leakage over the entire tumor. Focal argon laser treatment to the neovascular membrane alone did not cause permanent resolution of the subretinal fluid. The fluid did resolve, however, after the entire area of diffuse leakage was retreated with photocoagulation. In one of the patients who received both focal and confluent laser treatment, the choroidal tumor grew in a collar-button fashion through Bruch's membrane at the original site of focal treatment. This eye was enucleated, and results of histopathologic examination showed a choroidal melanoma.
