A 29-year-old woman was referred to our department for corneal edema after uneventful pterygium excision surgery with conjunctival autografting. She was prescribed topical dexamethasone and showed a complete response within 2 weeks of treatment. Specular microscopic examination revealed severe endothelial cell loss in the operated eye. Mild corneal haze causing a decrease in vision (20/50) was observed in long-term follow-up. This steroid-responsive complication was linked to two possible etiologies: mild toxic anterior segment syndrome or povidone-iodine (PVP-I) corneal toxicity. Surgeons should be careful during pterygium surgery to completely clear PVP-I and avoid any penetration into the anterior chamber to prevent possible serious complications. When diffuse corneal edema is encountered after pterygium surgery, intense steroid treatment should be prescribed as in the present case.
一位 29 岁女性在接受翼状胬肉切除联合结膜自体移植术后无明显异常，因角膜水肿被转至我科。她接受了局部地塞米松治疗，治疗 2 周内完全缓解。共焦显微镜检查显示手术眼内皮细胞严重丢失。在长期随访中发现轻度角膜混浊导致视力下降（20/50）。这种对类固醇有反应的并发症可能与两种病因有关：轻度毒性前节综合征或聚维酮碘（PVP-I）角膜毒性。在翼状胬肉手术中，外科医生应小心操作，以彻底清除 PVP-I 并避免任何穿透前房，以防止可能发生的严重并发症。如本例患者，当翼状胬肉手术后出现弥漫性角膜水肿时，应给予强的松龙治疗。
