Everolimus is a secondary medication for metastatic renal cell carcinoma when vascular endothelial growth factor inhibitor treatment fails. Everolimus is reported to cause a variety of metabolic complications but complications in the eye are rare. Although serious eye complications have not been reported, secondary complications may result from the metabolic complications. We observed a case in which central retinal vein occlusion occurred, probably caused by metabolic complications following Everolimus treatment of RCC. We report this case.
