目的 :观察 810nm半导体红外线激光经巩膜睫状体光凝术 (transcleraciliaryphotocoagnlationTSCPC)治疗难治性青光眼的临床效果。方法 :应用法国BVI公司生产的 810nm半导体红外线激光仪 ,经光纤将能量传输到激光头 ,在距角膜缘后 1.2～ 1.5mm ,紧贴眼球壁 ,使激光头与视轴平行 ,设置激光能量 1.8～ 2 .2W ,时间 2～ 3s,发射激光后听到眼内“爆破声”作为治疗能量的阈值 ,间隔 2mm进行一个光凝点 ,共 18～ 2 0个点 ,术后一月和二月观察眼压等变化情况。结果 :本组 6 2例患者术前眼压难以用手术或药物控制 ,范围在 38～ 85mmHg ,平均 (4 6 .2± 11.76 )mmHg ,经治疗后一月内眼压有 6 7.74%控制在 30mmHg以下 ,二月内有 93.5 5 %眼压控制在 30mmHg以下 ,其中 75 .81%控制在正常范围。结论 :810nm半导体红外线激光行TSCPC治疗难治性青光眼是一种安全有效 ,操作简单 ,易于掌握 ,患者乐于接受的治疗方法
Objective: To observe the clinical effect of 810nm semi-conductor infrared laser transscleral ciliary photocoagulation (TSCPC) in refractory glaucoma. Methods: 810nm semiconductor infrared laser produced by BVI in France was used to transmit the energy to the laser head through the optical fiber. The distance from the limbus was 1.2 ~ 1.5mm, close to the wall of the eyeball. The laser head was parallel to the visual axis, and the laser energy 1.8 ~ 2 .2W, time 2 ~ 3s, laser emission after hearing the “blasting sound” of the eye as the threshold value of treatment energy, a photocoagulation point 2mm intervals, a total of 18 ~ 20 points, after January and February Observation of intraocular pressure and other changes. Results: The preoperative intraocular pressure of 62 patients in this group was difficult to control by surgery or medication, ranging from 38 to 85mmHg, with an average of (46.2 ± 11.76) mmHg. Intraocular pressure was 6.74% within one month after treatment 30mmHg the following February 93.5 5% intraocular pressure control in the following 30mmHg, of which 75.81% control in the normal range. Conclusion: 810nm semiconductor infrared laser TSCPC treatment of refractory glaucoma is a safe and effective, simple, easy to grasp, the patient is willing to accept the treatment
