PURPOSE
To ascertain the association between the improvement of diabetic macular edema and increased visual acuity after pars plana vitrectomy.
METHODS
From January 1994 to December 1996 we prospectively studied 18 patients (18 eyes, 7 women and 11 men, mean age 52 years, range 37-68) with type II diabetes and clinically significant macular edema. One group was composed of 9 patients presenting diffuse macular edema (DME); a second group with 9 patients presented cystoid macular edema (CME). All patients underwent pars plana vitrectomy.
RESULTS
Preoperative Snellen visual acuity was 20/143 in DME and 20/441 in CME. In both groups vision increased to 20/136 and 20/205, respectively, postoperatively. For the DME this difference was statistically significant (p<0.05) at 1 month after the surgery, but vision decreased again after 10 months reaching preoperative values.
CONCLUSIONS
Our results suggest that pars plana vitrectomy for diabetic macular edema may increase visual acuity in diffuse macular edema, although this increase is only short lived.
目的
确定玻璃体切割术后糖尿病性黄斑水肿的改善与视力提高之间的关联。
方法
1994年1月至1996年12月，我们前瞻性研究了18例患有II型糖尿病且有临床显著性黄斑水肿的患者（18只眼，7名女性和11名男性，平均年龄52岁，范围37 - 68岁）。一组由9例表现为弥漫性黄斑水肿（DME）的患者组成；另一组9例患者表现为黄斑囊样水肿（CME）。所有患者均接受了玻璃体切割术。
结果
术前DME组的Snellen视力为20/143，CME组为20/441。两组术后视力分别提高到20/136和20/205。对于DME组，术后1个月时这种差异具有统计学意义（p<0.05），但10个月后视力再次下降至术前水平。
结论
我们的结果表明，玻璃体切割术治疗糖尿病性黄斑水肿可能会提高弥漫性黄斑水肿患者的视力，尽管这种提高只是短暂的。
