Management of ciliary body melanoma with iodine-125 plaque brachytherapy.
OBJECTIVE
Because ciliary body melanoma often defies early diagnosis, and its treatment is controversial, we report our experience with the clinical presentation and management of ciliary body melanoma, treated with iodine-125 plaque brachytherapy.


METHODS
A retrospective noncomparative case series.


METHODS
Forty-two patients with ciliary body melanoma treated with iodine-125 brachytherapy.


METHODS
Electronic chart review of ciliary body melanoma patients treated at Princess Margaret Hospital, University of Toronto, Toronto, Ont. Patients' demographics and clinical, management, and follow-up data, including brachytherapy-related complications, were reviewed. Outcome measures included rates of tumour control, eye preservation, systemic metastases, and brachytherapy-related complications.


RESULTS
Median age at diagnosis was 58 years and median follow-up was 43 months. Ciliary body melanoma was asymptomatic in 55% of patients, whereas floaters or flashes were the main symptom in 33%. Median tumour thickness before brachytherapy was 5.2 mm and after brachytherapy was 3.3 mm. Radiation-induced cataract was the main complication in 55% of patients, radiation retinopathy in 24%, and neovascular glaucoma in 15%, which was controlled by topical treatment in half of the cases. Two patients developed metastases and 3 required secondary enucleation.


CONCLUSIONS
Medium-sized ciliary body melanoma produced no or minimal symptoms on presentation in 88% of the patients. Iodine-125 plaque brachytherapy offered 98% tumour control at 43 months' follow-up. Radiation-related complications are generally manageable in most patients, which permits retention of the treated eye.
