Abstract
Choroidal melanoma is the commonest adult primary intraocular tumour,1 and usual sites of secondary spread are to liver, bone and lung. Although delayed recurrence of ipsilateral orbital melanoma is well documented, metastasis to the contralateral orbit is a rarely encountered phenomenon. We describe a case of metastatic spread to the contralateral orbit in a patient 12 years after proton beam radiotherapy of choroidal melanoma.
Highlights
A 73 year old lady attended ophthalmic outpatients in 1993 describing photopsia in her left pseudophakic eye
The clinical appearance was consistent with malignant melanoma of the choroid and ultrasound (U.S.) B scan demonstrated a lesion of 14 mm width and 7 mm height
Following referral to a national centre for ocular oncology, a course of proton beam radiotherapy was instituted and the patient attended for regular follow up
