lüll Radiation retinopathy Zamber RW; Kinyoun JLWest J Med 1992[Nov]; 157 (5): 530-3Radiation therapy is effective against many cancerous and noncancerous disease processes. As with other therapeutics, side effects must be anticipated, recognized, and managed appropriately. Radiation retinopathy is a vision-threatening complication of ocular, orbital, periorbital, facial, nasopharyngeal, and cranial irradiation. Factors that appear important in the pathogenesis of radiation retinopathy include total radiation dosage, fraction size, concomitant chemotherapy, and preexisting vascular disorders. Clinical manifestations of the disorder include macular edema and nonproliferative and proliferative retinopathy, similar to changes seen in diabetic retinopathy. Argon laser photocoagulation has proved efficacious for managing macular edema and fibrovascular proliferation in some of these patients. Ongoing basic laboratory and clinical research efforts have led to a better understanding of the pathogenesis, natural history, and treatment response of radiation retinopathy. The ultimate goal of this knowledge is to improve the prevention, recognition, and management of this vision-threatening complication.|*Radiation Injuries[MESH]|Fluorescein Angiography[MESH]|Humans[MESH]|Radiotherapy/*adverse effects[MESH]|Retina/pathology/*radiation effects[MESH]|Retinal Diseases/diagnosis/*etiology/pathology[MESH] |
