首次报告5例视网膜脱离手术后植入物穿过肌止端前移这种罕见的并发症。5例均采用同样的手术技术:用5.0编织聚酯线将环状面的硅胶植入物固定于巩膜表面,缝线跨度宽于植入物3mm,术中均未断直肌。手术至发现植入物前移的间隔时间为6个月至8年。植入物分别穿过内、上、外直肌止端前移,固定植入物的缝线3例被割断,2例因植入物脱出而未看见。2例植入物脱出于结膜外在局麻下取出,另3例留在原处。
The first reported 5 cases of retinal detachment surgery after the insertion of the implant through the muscle end of this rare complication. The same surgical technique was used in all 5 cases: a circular braided silicone implant was fixed on the surface of the sclera with a 5.0 braided polyester thread, and the suture span was 3 mm wider than the implant. The time between surgery and discovery of implant advancement was 6 months to 8 years. The implants were advanced through the ends of the medial, upper and lateral rectus respectively. The suture of the fixed implants was severed in 3 cases and the other 2 cases were not seen due to the prolapse of the implants. 2 cases of implant prolapse in the conjunctiva outside the local anesthesia removed, and the other 3 remained in place.
