Fourteen patients treated with 125I brachytherapy at an ocular oncology referral center from 1974 through 1996, all of whom had had previous debulking, incomplete resection, or recurrence after surgery. A stainless steel pericorneal ring eyeshield was attached to the extraocular muscles, over which a lid was fitted to protect the cornea without touching it. Iodine-125 seeds in polythene tubes were inserted into the eyelid and attached to the lid margin for a single plane implant. In five cases additional seeds were glued on to the shield as well for a volume implant. Local control is regarded as freedom from recurrence in those without measurable disease and complete clinical regression in those with measurable disease.
Morbidity is assessed in terms of function and cosmesis.
Survival is given from the time of the implant. There were two recurrences at 8 and 13 months in the first patient who received 17.3 Gy. Late complications consisted of mild eyelid telangiectasia, mild eyelid atrophy, and loss of eyelashes in most patients. Five patients, four of whom had upper eyelid tumors, experienced a dry eye, which was managed with tear supplements, and one of these patients developed a cataract. A corneal ulcer developed in one eye, which later perforated after treatment of a subsequent bulbar melanoma and was exenterated.
