A 55-year-old woman with chronic renal failure treated with hemodialysis had severe bilateral visual loss develop due to retinal ischemia. Ophthalmoscopy showed crystals in the distribution of the retinal arteries, but not veins, and this led to a diagnosis of systemic oxalosis. Factors contributing to systemic oxalosis in addition to renal failure were ascorbic acid dietary supplementation, pyridoxine deficiency, and ileal resection. Histopathologic findings showed ocular calcium oxalate deposition limited nearly entirely to the walls of retinal blood vessels.
一名接受血液透析治疗的55岁慢性肾衰竭女性因视网膜缺血出现严重双侧视力丧失。眼底镜检查显示视网膜动脉分布区有结晶，但静脉无结晶，这导致诊断为全身性草酸盐中毒。除肾衰竭外，导致全身性草酸盐中毒的因素还有饮食中补充抗坏血酸、维生素B6缺乏和回肠切除术。组织病理学检查结果显示，眼部草酸钙沉积几乎完全局限于视网膜血管壁。
