蚕食式膜切除术在糖尿病视网膜病变中的应用

目的:从术中术后并发症的发生率评价蚕食式膜切除术在糖尿病视网膜病变中的作用。方法:对比分析了行普通撕膜技术的31例(34只眼)和行蚕食式膜切除术的52例(58只眼)术中术后并发症的发生率。结果:蚕食式膜切除术组发生医源性视网膜裂孔2只眼,普通手术组7例(P<0.05);蚕食式膜切除术组术中出血4只眼,普通手术组15只眼(P<0.01);蚕食式膜切除术组术后有6只眼发生Ⅲ级反应,普通手术组有5只眼(P>0.05)。结论:糖尿病视网膜病变中使用蚕食式膜切除术剥膜比较安全,能减少手术中及手术后并发症。

Nibble Technology in Diabetic Retinopathy

PURPOSE: To evaluate the nibble technology in the therapy of diabetic retinopathy. METHODS: Eighty-three patients (ninety-two eyes) with proliferative diabetic retinopathy were treated in our department. All the patients received a standard pars plana vitrectomy. Fifty-two of them (fifty-eight eyes) were treated with nibble technology, while the other thirty-one (thirty-four eyes), who were treated with common procedure to tear the proliferative membrane, were served as a control group. RESULT: The operative complication of iatrogenic retinal tears was observed in 2 eyes of the test group and 7 eyes of the control group (P < 0.05). Another operative complication of hemorrhage was observed in 4 eyes of the test group and 15 eyes of the control group (P < 0.01). There were 6 eyes of the test group and 5 eyes of the control group presented with grade-III postoperative responds (P > 0.01). CONCLUSION: The nibble technology is safe in the therapy of proliferative diabetic retinopathy and could reduce the complications during or after the operation.
