PURPOSE
To report a case of delayed spontaneous Descemet membrane (DM) tear after big-bubble Deep Anterior Lamellar Keratoplasty (DALK).
METHODS
Uneventful big-bubble DALK was performed on a 29-year-old patient with advanced keratoconus. No injury to DM was noted intraoperatively and in the first postoperative week. On examination after 1 month, the patient presented with tear and partial detachment of Descemet membrane (DMD).
RESULTS
Circumscribed eccentric stromal edema, but not DMD, partially resolved after a 3-month observational period.
CONCLUSIONS
A tear to DM and consecutive DMD may occur spontaneously after big-bubble DALK. Sutural traction and regressing corneal stromal edema may be etiologic factors.
目的
报告1例大泡性深前板层角膜移植术（DALK）后迟发性自发性后弹力层（DM）撕裂的病例。
方法
对1例晚期圆锥角膜患者行顺利的大泡性DALK。术中及术后第1周未发现DM损伤。术后1个月检查时，患者出现后弹力层撕裂及部分脱离（DMD）。
结果
经过3个月的观察期，局限性偏心性基质水肿而非DMD部分消退。
结论
大泡性DALK后DM可能会自发撕裂并连续发生DMD。缝线牵引和角膜基质水肿消退可能是病因。
