二极管激光在眼底病中的应用

目的观察二极管激光在各种眼底病伴有屈光间质混浊中的光凝效果。方法对各种眼底病伴有屈光间质混浊４３例（４７只眼）及玻璃体视网膜手术４０例（４２只眼）采用间接检眼镜式光凝,行手术患者于术中行眼内光凝。结果视力进步者占２４．７％,视力不变者占６２．９％,视力下降者占１２．４％。增殖性糖尿病性视网膜病变中新生血管退行性变者占７８．３％（４７／６０只眼）,视网膜裂孔全部封闭。结论在屈光间质混浊但能见眼底的患眼及术中采用二极管激光光凝治疗者效果好,未见明显副作用。

Application of diode laser in the operation of retinal diseases

Objectives To evaluate the effects of diode laser photocoagulation applied on 43 cases of various kinds of fundus diseases with media opacity and on 40 cases during vitreo retinal surgery. Methods Indirect ophthalmoscope laser photocoagulator was used for fundus diseases, and endolaser used during surgery. Results Vision was improved in 24.7% of the eyes, and was unchanged in 62.9% of the eyes. The neovascularization in proliferative diabetic retinopathy regressed in 78.3% of the eyes. All the retinal holes were closed. Conclusions Diode laser can be used for treatment of some retinal diseases and in the operation. Good results can be obtained in the eyes with some extent of media opacity. No obvious side effect was observed.
