阈下微脉冲激光在黄斑疾病中的应用

Application of subthreshold micropulse laser on treatment of macular disorders

微脉冲激光是一种短促高频的重复脉冲激光,已成为多种视网膜疾病的有效治疗方式。与传统激光相比,阈下微脉冲激光不伴有视网膜的热损伤,可用于黄斑区疾病的治疗。目前已广泛用于治疗糖尿病性黄斑水肿(diabetic macular edema,DME)、视网膜静脉阻塞(retinal vein occlusion,RVO)伴发的黄斑水肿以及中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)并取得了一定效果,但其能量参数的设置标准、安全性及成功率等问题还需要进一步研究。

Subthreshold micropulse laser treatment consists of short,repetitive pulses of laser,and has shown efficacy in multiple retinal conditions.In contrast to the conventional laser,the therapeutic effect of the subthreshold micropulse laser is not accompanied by thermal retinal damage.This fact is of particular importance when a treatment near the fovea is required.Micropulse treatment is applied in indications such as diabetic macular edema(DME),macular edema due to retinal vein occlusion(RVO),or central serous chorioretinopathy(CSC)and proved effective.
