Description/Abstract | Lymphoma of the conjunctiva is rare.^It presents in older patients as a mass lesion and usually remains localized.^Surgery is limited to biopsy, and radiation therapy is the definitive treatment of choice.^The entire conjunctiva is treated.^Relatively high doses (approximately 30 Gy) are required for local control, which may lead to cataract formation.^Twelve patients with conjunctival lymphoma were treated at the Massachusetts General Hospital between 1979 and 1988.^Ten of 12 patients presented with a unilateral lesion; 2 of 12 with bilateral lesions.^Two of 12 patients were found to have systemic disease at the time of presentation.^One patient developed conjunctival lymphoma 5 years after the diagnosis of generalized disease.^Using electron beam, all patients were treated with a single anterior circular field to total doses ranging from 24 Gy to 30 Gy delivered in 8 to 16 fractions over 9 to 20 days.^In all cases, the lens was shielded by a specially designed plastic contact lens bearing a 12 mm diameter lead shield.^The lens dose was determined at varying depths beneath the shield for 6 MeV and 9 MeV electron beams and ranged from a minimum of 5% to an absolute maximum of 18% of the total dose delivered to the tumor.^Local control was maintained in all patients with follow-up to 9 1/2 years.^One patient relapsed distantly 3 years after treatment.^One of 12 patients died of systemic disease 4 years after treatment of the ocular lesion.^Two patients developed cataracts 4 and 5 years after treatment; one had bilateral cataract, although only one eye had been treated.^Both patients were over 75 years old.^In both cases, the cataracts were felt to be senile cataracts which are ophthalmologically and radiographically distinguishable from radiation induced lesions. |
