目的:探讨激光光凝联合白内障术对糖尿病黄斑水肿合并白内障患者视力及黄斑水肿的改善分析。
方法:选取2014-01/2015-07期间来我院就医并确诊为糖尿病性黄斑水肿合并白内障的患者60例72眼为研究对象,采用随机数字表法随机将患者分为两组,对照组及观察组,各30例36眼,观察组患者接受白内障术前行激光光凝的联合治疗,对照组患者接受白内障术后行激光光凝的联合治疗,手术2mo后对患者进行视力检查、散瞳眼底检查、裂隙灯显微镜检查、黄斑区光学相干断层扫描(OCT)、眼底血管荧光造影检查(FFA)等常规检查。
结果:观察组与对照组患者在治疗前两组视力比较,差异无统计学意义(P>0.05)。手术2mo对患者行视力检查发现,两组患者在治疗后视力状况均得到明显改善,视力明显提高,与治疗前视力相比,差异有统计学意义(均P<0.05),治疗后观察组患者视力状况显著优于对照组,差异具有统计学意义(P<0.05)。观察组与对照组患者在治疗前两组患者眼部黄斑厚度比较,差异无统计学意义(P>0.05)。手术2mo对患者眼部黄斑厚度检查发现,两组患者在治疗后眼部黄斑厚度均下降,与治疗前黄斑厚度相比,差异有统计学意义(均P<0.05)。治疗后观察组患者眼部黄斑厚度下降程度显著多于对照组,差异具有统计学意义(P<0.05)。
结论:在行白内障术前进行激光光凝治疗对糖尿病性黄斑水肿合并白内障的视力及黄斑厚度改善有更好的效果。

AIM:To explore laser photocoagulation with cataract surgery for improvement of visual acuity and macular edema in patients with cataract and diabetic macular edema.
METHODS:A total of 60 patients(72 eyes)from January 2014 to July 2015 in our hospital were selected, which all were diagnosed as cataract with diabetic macular edema. According to a random number table method, the patients were divided into observation group and control group, 30 cases(36 eyes)in each group. The observation group was treated with combination therapy of laser photocoagulation before cataract surgeries, while the control group with the combination therapy of laser photocoagulation after cataract surgeries. At 2mo after surgeries, some routine examination, such as visual acuity, fundus examination after mydriasis, slit lamp examination, optical coherence tomography(OCT)examination, fluorescence angiography examination(FFA)for retinal blood vessels were applied in all the patients.
RESULTS:The visual acuity of the observation group and the control group before treatments was not significantly different(P>0.05). At 2mo after treatments, the visual inspection showed that compared with the visual acuity before treatment, the visual acuity of the two groups were both significantly improved(P<0.05); besides, the visual acuity of the observation group was significantly better than that of the control group after treatments, the difference was statistically significant(P<0.05).The macular thickness of the observation group and the control group before treatments was not significantly different(P>0.05). At 2mo after treatments, compared with those before treatments, the macular thickness of two groups were both significantly improved(P<0.05); besides, the macular thickness of the observation group was significantly better than that of the control group, and the difference was statistically significant(P<0.05).
CONCLUSION:The laser photocoagulation before cataract surgery for patients with cataract and diabetic macular edema can significantly improve their visual acuity and macular thickness.
