Radiotherapy in benign orbital disease. I: Complicated ocular angiomas.

Radiotherapy has been successful in the management of complicated ocular and orbital angiomas, but late morbidity (particularly radiation induced cataract) has been a problem. With modern radiotherapy techniques it is possible to minimise the morbidity to other tissues. By means of a recently developed method of lens-sparing ocular radiotherapy (initially adopted for retinoblastoma therapy) two cases of diffuse ocular haemangioma complicated by retinal detachment have been treated, with evidence of regression.
