三位一体移植治疗眼部化学及热烧伤

目的：观察角膜、角膜与结膜移植治疗眼部化学烧伤与热烧伤的效果。方法：采用严重化学烧伤与热烧伤病例（6例7眼），作异体角膜板层或全层膜、角膜缘与球结膜，即“三位一体”移植，术后滴用地寒米松或联用环孢酶素A。结果：在6个月至2年追踪观察期内，7眼中有3眼例达到了睑球粘连分离的目的，防止了假性胬肉的复发，减少了角膜新生血管3眼部分改善。4眼（57．1％）植片基本透明，1眼术后再粘连与假性胬肉复发。3眼植片大部分或全混浊。结论：角膜与角膜缘和粘膜“三位一体”移植治疗化学烧伤与热烧伤，术后联用激素与环孢霉素A有较好效果。

Management of severe ocular chemical or thermal burns with transplantation of trinity

To evaluate the clinical effects of corneal, limbal and conjunctival transplantation. Methods: Laminar cornea or full cornea, limbal and conjunctival transplantation of trinity, dexamethasone and cyclosporin A eye drops were used for 6 patients (7 eyes) with old chemical or thermal burns.Results: In the 6-24 months of follow-up, the results showed symblepharon, neovascularization and psuedopterygium were prevented or decreased obviously in 6 eyes. Corneal epitheliums were stable and grafts were transparent in 4 eyes. Psuedopterygium and symblepharon relapsed in 1 patient and grafts were opaque in 3 eyes. Conclusions: Transplantation of trinity and application of dexamethasone or cyclosporin A seems an effective treatment for severer chemical or thermal burns of eyes.
