To report a new complication of 360 degrees suture trabeculotomy attributable to subretinal suture misdirection.
Observational case report.
Retrospective chart review.
A 5-month-old female with bilateral congenital glaucoma underwent uncomplicated 360 degrees suture trabeculotomy in the right eye. In the left eye, a scleral flap was created and dissection to Schlemm's canal was achieved. A 6-0 Prolene suture was passed into Schlemm's canal long enough for 360 degrees of treatment, did not come out the opening, and was retracted. The procedure was completed with a trabeculotome. One month later, an unusual white tract was noted subretinally in the left eye. There was no overlying retinal break or detachment. The tract presumably was caused by the misdirected Prolene suture exiting Schlemm's canal prematurely and being directed posteriorly.
Suture misdirection subretinally during cannulation of Schlemm's canal should be considered a possible complication of 360 degrees suture trabeculotomy.
报告360度缝线小梁切开术一种因视网膜下缝线误置导致的新并发症。
观察性病例报告。
回顾性病历审查。
一名5个月大的双侧先天性青光眼女性右眼顺利接受了360度缝线小梁切开术。在左眼，制作了巩膜瓣并成功分离至施莱姆管。一根6-0聚丙烯缝线插入施莱姆管足够长以进行360度治疗，未穿出开口并被回拉。手术用小梁切开刀完成。1个月后，左眼视网膜下发现一条异常的白色条索。没有上方视网膜裂孔或脱离。这条条索推测是由于聚丙烯缝线过早穿出施莱姆管并向后移位所致。
在施莱姆管插管过程中视网膜下缝线误置应被视为360度缝线小梁切开术的一种可能并发症。
