Peripheral subretinal pigment accumulation following transpupillary thermotherapy for choroidal melanoma.
Transpupillary thermotherapy (TTT) used as either an adjunct to plaque brachytherapy or a primary treatment for choroidal melanoma can cause several intraocular complications, particularly in the retina. A 61-year-old woman had a macular choroidal melanoma measuring 8 x 7.5 X 3.6 mm and received TTT in three sessions, each 6 months apart. After the second treatment, pigmented material began to accumulate on the peripheral retina with an increasing pace. The tumor gradually regressed for 16 months, followed by a sudden regrowth. Enucleation of the eye revealed that the peripheral subretinal pigmented deposits consisted of pigment-laden macrophages and retinal pigment epithelial cells without viable tumor cells. The rare complication of peripheral subretinal pigment dispersion following TTT should not be alarming, but close monitoring is recommended.
