Treatment options for choroidal malignant melanoma: a case report featuring transpupillary thermotherapy.
BACKGROUND
Choroidal melanoma is the most common primary ocular tumor in adults. These tumors are almost always unilateral and develop spontaneously or arise from pre-existing nevi. Historically, treatment for choroidal melanoma was enucleation. New therapies have been developed to treat choroidal melanoma and to preserve the eye. Currently, these treatment options include brachytherapy and transpupillary thermotherapy.


METHODS
A 51-year-old man came to the eye clinic with symptoms of mildly decreased fluctuating vision and floaters with no flashes in the temporal visual field of the right eye. Best-corrected visual acuities were 20/30 O.D. and 20/20 O.S. A small-to-medium choroidal lesion was found in the right eye. Ultrasonography and A-scan showed this lesion to be a choroidal malignant melanoma. The patient's surgical options included enucleation, brachytherapy, and transpupillary thermotherapy. The patient opted to have transpupillary thermotherapy to preserve the eye, and subsequently underwent two procedures that eventually obliterated the melanoma, resulting in best-corrected visual acuity of 20/40.


CONCLUSIONS
Transpupillary thermotherapy is an excellent option for treatment of small-to-medium choroidal melanomas. Brachytherapy is also an option for treatment, but with increased ocular side effects and complications. Enucleation is still commonly performed on medium and/or large choroidal melanomas.
