PURPOSE: To describe a case of radiation choroidopathy manifesting drastic remodeling of choroidal drainage routes. METHOD: Case report. A 34-year-old man who had received radiation treatment for a tumor in the upper eyelid of his right eye 15 years earlier had floating black spots. He was examined ophthalmologically, including with indocyanine green angiography using a scanning laser ophthalmoscope. RESULTS: The right eye manifested classic features of radiation retinopathy in the superior fundus. Indocyanine green angiography showed vaso-occlusion of choroidal arteries, capillaries, and veins in a wider area than that affected by radiation retinopathy. The superotemporal vortex vein was obliterated, resulting in a remodeling of the choroidal veins in the same quadrant. The blood in this quadrant drained into the inferotemporal vortex vein through collateral venovenous drainage routes. CONCLUSION: The diagnosis in this eye was radiation retinopathy and radiation choroidopathy. Choroidal vascular lesions were more pronounced and involved a wider area than retinal vascular lesions did. This case illustrates that the choroidal veins may manifest a vast plasticity to remodel the drainage route after obliteration of a major vortex vein. |
