PURPOSE
To report a case of optic neuropathy after epi-LASIK.
METHODS
A 24-year-old man developed optic neuropathy after epi-LASIK, possibly related to the barotrauma created by the suction ring. Optic neuropathy and steroid-induced ocular hypertension were diagnosed. Prednisolone drops were discontinued and timolol was started.
RESULTS
After 2 weeks, his symptoms improved and the pain resolved.
CONCLUSIONS
Optic neuropathy is a potentially vision-threatening complication of epi-LASIK. Barotrauma from a transient increase in intraocular pressure created by the suction ring can be an important factor in this entity.
目的
报告1例上皮瓣下角膜磨镶术（epi-LASIK）后发生视神经病变的病例。
方法
一名24岁男性在epi-LASIK术后发生视神经病变，可能与吸引环产生的气压伤有关。诊断为视神经病变和类固醇诱导的高眼压。停用泼尼松龙滴眼液并开始使用噻吗洛尔。
结果
2周后，他的症状改善，疼痛缓解。
结论
视神经病变是epi-LASIK潜在的视力威胁性并发症。吸引环引起的眼内压短暂升高导致的气压伤可能是该病症的一个重要因素。
