氩绿激光治疗糖尿病性黄斑病变的临床观察

目的 探讨氩绿激光治疗糖尿病性黄斑病变的对改善视力及黄斑水肿的疗效。方法 将对糖尿病性黄斑病变患者按病程分成两组:增殖前期;增殖期。并行眼底荧光血管造影确定视网膜血管渗漏点(区)。对局部渗漏点氩激光点状光凝,弥漫性渗漏区采用格栅样光凝。随访12个月,观察比较两组光凝前后视力及黄斑水肿、渗漏的变化,并进行统计学分析。结果 氩绿激光治疗糖尿病性黄斑病变86例136眼,87.50%的眼别提高或保存现有视力,其中对增殖前期的疗效为优;87.95%的黄斑水肿完全或部分消退,增殖前期的黄斑水肿消退尤为明显。两组的视力改善和黄斑水肿消退比较均有统计学意义。结论 氩绿激光光凝是治疗糖尿病性黄斑病变的有效手段,有助于提高或保存现有视力,疗效与病变程度有关,早期治疗效果较好。

Therapeutic effect of argon green laser for diabetic retinopathy

Objective To investigate the therapeutic effect of argon green laser for improving the visual acuity and relieving diabetic macular oedema in patients with diabetic retinopathy (DR). Methods In patients with preproliferative DR (PPDR) and proliferative DR (PDR), fundus fluorescein angiography (FFA) was performed to locate the area or spot where leakage occurred, followed by argon green laser photocoagulation of the identified leakage. In the 1-year-long follow-up study, both the visual acuity and changes in diabetic macular oedema were observed in both groups. Results Altogether 136 eyes (86 cases) were treated with argon green laser photocoagulation, and 87.50% of them showed improvement or maintenance of the visual acuity, and 87.95% showed alleviation of diabetic macular oedema. Better therapeutic effects were achieved in PPDR than PDR group, with statistically significant difference. Conclusion Argon green laser can be an effective treatment modality for diabetic maculopathy and may improve or maintain the visual acuity of the patients, but the effects can be related to the stage of the disease. Earlier intervention ensures better results.
