玻璃体手术治疗弥漫性非牵引性糖尿病性黄斑水肿的临床效果

目的 探讨玻璃体切除联合视网膜内界膜剥除术治疗弥漫性非牵引性糖尿病性黄斑水肿的临床疗效.方法 回顾性病例系列研究.回顾性分析21例(21只眼)弥漫性非牵引性糖尿病性黄斑水肿患者的临床资料.所有患者均进行了玻璃体切除联合内界膜剥除术.患者手术前与手术后的黄斑厚度比较,采用定量资料配对t检验;术前与术后不同时间的视力呈非正态分布,采用Wilcoxon秩和检验.结果 患者术后随访12～24个月,平均16个月.术后1个月黄斑厚度由术前的(406±59)μm下降至(291±67)μm(t=9.26),术后3个月黄斑厚度(279±66)μm(t=16.09),术后6个月黄斑厚度(278±71)μm(t=10.15),术后12个月黄斑厚度(280±77)μm(t=9.46),术前与术后不同时间的黄斑厚度比较差异均有统计学意义(P<0.01);表明手术后黄斑水肿情况均有不同程度改善.手术后最终随访,最佳矫正视力改善8例(38.1%),不变11例(52.4%),下降2例(9.5%),术后与术前最佳矫正视力比较差异无统计学意义(Z=1.695,P＞0.01).结论 玻璃体切除联合内界膜剥除术能有效减轻弥漫性非牵引性糖尿病性黄斑水肿患者的黄斑厚度,但多数患者术后视力无明显改善.(中华眼科杂志,2011,47:492-496)

Abstract：

Objective To evaluate the efficacy of vitrectomy combined with internal limiting membrane (ILM) peeling in the treatment of diffuse nontractional diabetic macular edema. Methods It was a retrospective case series study. Clinical records of 21 consecutive patients (21 eyes) with diffuse diabetic macular edema without macular traction were reviewed. All patients underwent pars plana vitrectomy with internal limiting membrane peeling. Main outcome measurements included pre- and postoperative optical coherence tomography (OCT) and visual acuity. Results Postoperative follow-up ranged from 12 to 24 months (mean, 16.3 months). Mean preoperative foveal thickness significantly decreased from (406±59) μm to (291±67) μm at 1 months after surgery (t=9.26,P<0.01), and further decreased to (280±77) μm at 12 months (t=9.46,P<0.01). No differences in visual acuity between preoperative and postoperative were found during follow-up periods. The final best-corrected visual acuity improved in 8 (38.1%) of the 21 eyes, remained unchanged in 11 eyes (52.4%), and decreased in 2 eyes (9.5%). Conclusions Pars plana vitrectomy with internal limiting membrane peeling appears to be beneficial in eyes with diffuse nontractional diabetic macular edema in retinal thickness but visual acuity outcomes showed only minimal improvement as compared to the baseline.
