倍频Nd:YAG激光治疗初发和复发性中心性浆液性脉络膜视网膜病变

The evaluation of the effect of Double-frequency Nd:YAG laser photocoagulation on central serous chorioretinopathy

目的观察倍频Nd:YAG(532nm)激光治疗初发和复发性中心性浆液性脉络膜视网膜病变(CSC)的疗效。方法经荧光素眼底血管造影检查确诊的所有渗漏点距黄斑中心凹250μm以外的单眼CSC54例(54眼),行激光封闭治疗。其中初发病例38例(38眼),未曾行激光治疗的复发病例16例(16眼)。治疗前和治疗后1月行视力、相干光断层扫描(CT)和黄斑光敏感度检查。结果激光治疗后所有患者视力和黄斑光敏感度均有不同程度提高,且初发患者较复发患者改善明显;两组患者黄斑区渗液高度均降低,但黄斑水肿完全吸收率没有明显差异。结论倍频Nd:YAG(532nm)激光治疗初发和复发性CSC均取得显著疗效,初发患者的疗效较好。

Objective To evaluate the effect of double-frequency Nd：YAG lazer photocoagulation on incipient and recurrent central serous chorioretinopathy （CSC）. Methods 54 patients （54 eyes） with CSC diagnosed by fundus fluorescein angiography （FFA） that the distance of leaking point and macular fovea centralis was more than 250 μm were treated with double-frequency Nd：YAG laxer photocoagulation. In all patients 38 were incipience cases,16 were recurrence cases who were not received lazer photocoagulation. All patients were assessed by visual acuity,optical coherence tomography,and macular light sensitivity before and 1month after laser treatment. Results The visual acuity and macular light sensitivity of all patients were increased and the improvement of incipience cases is higher than recurrence cases. The height of effusion was all decreased,but there was no statistical significance of the rate of macular edema complete absorption in the two groups. Conclusion The effect of double-frequency Nd：YAG laxer photocoagulation on CSC is safe and effective,the effect of incipience cases is better than recurrence cases.
