方法：回顾性分析了我院2007-03/2012-03不同程度化学性或热烧伤患者28例28眼，其中13例角膜Ⅱ或Ⅲ度烧伤伴部分角膜缘Ⅳ度烧伤患者行新鲜羊膜遮盖术，15例全角膜Ⅲ度以上烧伤且全周角膜缘坏死不伴有严重眼睑缺损患者行新鲜羊膜移植术，术后随访6～24mo。术后主要观察视力、羊膜植片情况、角膜恢复情况及术后并发症。

结果：术后视力提高者20眼(71%)，不变者5眼(18%)，降低者3眼(11%)。羊膜移植片情况：28眼患者术后羊膜成活23眼，成活率达82%。角膜恢复情况：28眼中角膜最终恢复透明4眼，角膜云翳8眼，角膜斑翳10眼，角膜白斑4眼，2眼术后角膜表面进行性溶解，行板层角膜移植手术。羊膜脱落后暴露的角膜很快上皮化，但部分患者再次出现上皮缺损，经再次重复手术后稳定。

结论：新鲜羊膜遮盖和羊膜移植术是治疗急性期眼表热烧伤的有效方法。

METHODS: A retrospective analysis of 28 cases(28 eyes)affected by ocular chemical or thermal burn with different degree were included in our hospital from March 2007 to March 2012. Amniotic membrane patched was undergone in 13 eyes with fresh amnion that the patients corneal burns degree Ⅱ or Ⅲ with partial limbal buns at degree Ⅳ. Amniotic membrane grafts was performed in 15 eyes with fresh amnion that the patients all corneal burns at degree Ⅲ with the whole limbal necrosis without severe eyelid defect. The follow-up time ranged 6～24mo. The postoperative visual acuity, the condition of amniotic membrane transplant, renovation of cornea and complications were observed.

RESULTS: Postoperative corrected visual acuity was improved in 20 eyes(71%), it was not changed in 5 eyes(18%), the visual acuity declined in 3 eyes(11%). The amniotic membrane survived in 23 eyes and the survival rate was up to 82%. The cornea of 4 eyes recovered to transparent, nebula emceed in 8 eyes eventually, corneal macula emerged in 10 eyes, 4 eyes ended up with leukoma, 2 eyes developed corneal melting after therapy, then received lamellar keratoplasty. Corneal surface become epithelization after amnion patches or grafts, but any of them have recurrent epithelial erosion, and become stable epithalization after repeat operation.

CONCLUSION: Amniotic membrane patches and grafts is an effective method to deal with acute ocular surface burn.
