Mineral and bone metabolism disorders are relatively common among patients with end-stage renal disease on maintenance hemodialysis. Corneal and conjunctival calcification is the main extravascular site for calcification. Recently, this form of calcification has been linked to vascular calcification. Secondary hyperparathyroidism can lead to high levels of calcium and phosphorus and increase the risk of calcification. Here, we report a case of a 38-year-old female with severe hyperparathyroidism who underwent eye examination before and after parathyroidectomy. Anterior segment optical coherence tomography showed an improvement in the number and size of ocular calcifications 6 months after surgery. This case calls attention to the importance of eye examination in patients on dialysis and brings the possibility of recovery of calcification in a short-term follow-up.
矿物质和骨代谢紊乱在维持性血液透析的终末期肾病患者中较为常见。角膜和结膜钙化是血管外钙化的主要部位。最近,这种形式的钙化与血管钙化有关。继发性甲状旁腺功能亢进可导致钙、磷水平升高,增加钙化风险。在此,我们报告了一例 38 岁女性严重甲状旁腺功能亢进患者,在甲状旁腺切除术前和术后进行了眼部检查。眼前节光学相干断层扫描显示术后 6 个月眼部钙化的数量和大小有所改善。该病例提醒我们,在透析患者中进行眼部检查的重要性,并提示短期内钙化可能恢复。
