目的：探讨小牛血去蛋白提取物眼用凝胶对术中用丝裂霉素C的青光眼术后结膜漏水的修复能力。 方法：采取回顾性研究方法，将2007-01/2010-12我院青光眼小梁切除术后结膜漏水的患者分成不用小牛血去蛋白提取物眼用凝胶的对照组(A组)和用20%小牛血去蛋白提取物眼用凝胶的治疗组（B组），记录结膜在术后3，7，14d愈合的情况，评价其有效性。 结果：小牛血去蛋白提取物眼用凝胶治疗组能缩短结膜愈合时间，与不用小牛血去蛋白提取物眼用凝胶的对照组比较，差异有统计学意义（P<0.05）。 结论：小牛血去蛋白提取物眼用凝胶能有效促进结膜修复，减少丝裂霉素C使用后的并发症。

AIM:To evaluate the clinical efficacy of protein-free calf blood extract for conjunctiva-leaking after trabeculectomy in human eyes. METHODS:A retrospective study with control designa-tion was carried out from January 2007 to December 2010.The first group was conjunctiva-leaking eyes without protein-free calf blood extract.The second group of conjunctiva-leaking eyes was treated by 20% protein-free calf blood extract eye drops.The leaking of conjunctiva was recorded on day 3,7,14. RESULTS:There was significant difference between the two groups in conjunctival healing time (P<0.05). CONCLUSION:Protein-free calf blood extract eye drops has confirmed efficacy in treating conjunctiva-leaking after trabeculectomy.
