Primary treatment of choroidal amelanotic melanoma with photodynamic therapy.

ABSTRACT

The management of choroidal melanoma involves a delicate balance between preserving vision and preventing metastasis. Plaque brachytherapy has become standard management of most small lesions; however, this can result in radiation retinopathy and optic neuropathy. Transpupillary thermotherapy avoids these side-effects; however, it can also result in visual loss and its effectiveness is limited in amelanotic lesions. Photodynamic therapy with verteporfin has shown promise in animal studies of choroidal melanoma, and has recently been used in the management of lesions that have failed to respond to conventional therapy. The authors report a case of primary treatment of a small choroidal amelanotic melanoma with photodynamic therapy using verteporfin.
