Radiation retinopathy was encountered in 7 out of 10 survivors included in this study. Five of the affected patients lost vision as a result of the retinopathy. One patient required laser photocoagulation and responded well to this treatment. There was a variation in the severity of the retinopathy among the patients studied despite the fact that all patients received a similar dose of radiotherapy. We suspect that previously unrecognised factors in the planning of radiotherapy fields may explain this difference. ER -
