Serous detachments of the macula associated with presumed small choroidal melanomas

Eight cases of presumed small choroidal melanomas, associated with subretinal fluid in the macula, were studied to determine the eventual outcome of these tumors and the value of photocoagulation in eliminating subretinal fluid. Photocoagulation resulted in resolution of subretinal fluid involving the macula in six cases for a mean duration of 12 months. Six cases showed tumor growth over a mean interval of 24 months. Two cases were eventually managed with enucleation and two with I125 brachytherapy. The occurrence of subretinal fluid involving the macula in cases of small choroidal melanomas implies a high chance of subsequent tumor growth. Photocoagulation may be useful in eliminating subretinal fluid and improving vision during this observation period.
