PURPOSE
To report two cases of neurotrophic keratitis (NK) after micropulse transscleral cyclophotocoagulation (MP-TCP).
OBSERVATIONS
Two patients with predisposing factors for decreased corneal sensation developed NK 1 month after MP-TCP. Both patients did not heal with initial treatment with topical antibiotic and preservative free artificial tears. One patient required use of a bandage contact lens and the other patient required tarsorrhaphy. Both eyes experienced recurrence of NK.
CONCLUSIONS AND IMPORTANCE
NK can be triggered after MP-TCP in patients with underlying predisposing factors for decreased corneal sensation. This uncommon but vision-threatening complication should be discussed preoperatively with high-risk patients as a possible adverse event after MP-TCP and followed closely postoperatively.
目的
报告两例微脉冲经巩膜睫状体光凝术（MP-TCP）后发生神经营养性角膜炎（NK）的病例。
观察结果
两名有角膜感觉减退易感因素的患者在MP-TCP术后1个月发生NK。两名患者最初使用局部抗生素和无防腐剂人工泪液治疗均未愈合。一名患者需要使用绷带角膜接触镜，另一名患者需要睑裂缝合术。双眼均出现NK复发。
结论与重要性
对于有角膜感觉减退潜在易感因素的患者，MP-TCP术后可引发NK。这种罕见但威胁视力的并发症应在术前与高危患者讨论，作为MP-TCP术后可能的不良事件，并在术后密切随访。
