摘要
目的探讨用自体眼球筋膜囊组织修补外伤性角膜组织缺损的手术方法及效果。方法外伤性角膜组织缺损11例（11眼），首先将角膜伤口进行对位缝合，于角膜缺损处预置缝线，取自体结膜下组织（眼球筋膜囊）适量，填补于角膜缺损处，结扎预置缝线并加固缝合，对修补部位同时做结膜遮盖。术后观察角膜平滑程度、伤口密闭情况、眼压以及修补区局部变化。结果本组所有患眼术后角膜伤口均达到水密，角膜无明显皱褶，术后前房形成良好，眼压恢复正常，无伤口感染或眼内炎发生。随访观察1～6个月，眼球筋膜囊组织均成活，并逐渐瘢痕化及新生血管长入，上皮修复良好，无排斥反应、眼球筋膜囊组织自融或局部角膜膨隆发生。结论用自体眼球筋膜囊修复角膜组织缺损，材料来源容易、手术效果可靠，是治疗外伤性角膜部分缺损较好的手术方法。
Objective To explore the effect of gap-filling repair for traumatic corneal coloboma with autogenous Tenon＇ s capsule. Methods 11 cases （ 11 eyes） with coneal coloboma due to ocular trauma were studied. The corneal wound was sutured on the bit, pre-plaeed suture, gap-filling repaired with autogenous Tenon＇ s capsule, covered up with conjunctival flap. Coneal smoothness, wound obturation, intraocular pressure and the local change of the patch were observed after surgery. Results All the coneal wound were watertight, no obvious plica appeared, the anterior chamber were formed normaly, the intraocular pressure re- covered, and no wound infection or endophthalmitis occured after surgery. In 1 - 6 month＇ s follow up, the Tenon＇ s capsule tissue were alive and gradually scarring with neovascularization, and epithelium were re- paired. No rejection,Tenon＇ capsule tissue autolysis or local corneal bulge occurred. Conclusion Gap-fill- ing repair of the corneal coloboma due to ocular trauma with autogenous Tenon＇ s capsule is a ideal method. The Tenon＇ s capsule is easily obtained, and the surgical effect is reliable.
