Retinopathy secondary to radiation therapy for squamous cell carcinoma.
This report discusses a case of radiotherapy-induced retinopathy following treatment of squamous cell carcinoma. Treatment of the carcinoma with external beam radiotherapy to the supraorbital region and base of the skull was followed by the onset of retinopathy. The sensory retina, as well as other central nervous system tissues, is highly resistant to radiation damage; however, the retinal vasculature is extremely sensitive to radiation damage, producing a retinopathy that is characteristic of other vascular occlusive diseases. Management is discussed.
