810nm激光睫状体光凝治疗难治性青光眼的疗效

目的:探讨810nm激光经巩膜睫状体光凝治疗难治性青光眼的临床疗效。方法:对25例30眼难治性青光眼患者行810nm激光经巩膜睫状体光凝术,术后随访3mo,分析术后眼压、疼痛感、视力、并发症等情况。结果:术后随访期间全部患者眼痛症状均缓解。术前平均眼压为50.42±2.50mmHg,末次随访时平均眼压15.95±4.19mmHg,术后眼压与术前相比,差异有显著统计学意义(P<0.01)。光凝术后2眼(6.7%)视力提高,24眼(80.0%)视力无变化,4眼(13.3%)视力下降。术后前房渗出12眼(40.0%),前房积血3眼(10.0%),玻璃体积血1眼(3.3%),药物治疗后消失。结论:810nm激光经巩膜睫状体光凝术是治疗难治性青光眼的有效方法,能显著降低眼压,减少患者痛苦,并发症少。

Effect observation of 810nm laser cyclophotocoagulation for refractory glaucoma

AIM: To investigate the therapeutic effects of transscleral cyclophotocoagulation procedures(TCP)with 810nm laser for refractory glaucoma.

METHODS: Totally 25 patients(30 eyes)with refractory glaucoma were treated with TCP. The follow-up time was 3 months, the patients' symptom, intraocular pressure(IOP), visual acuity and complications were analyzed.

RESULTS: During the follow-up period, all patients' ocular pain was reduced. The mean IOP before TCP and at the last follow-up time were(50.42±2.50)mmHg(1kPa=7.5mmHg)and(15. 95±4.19)mmHg, respectively, the IOP decreased after TCP, there was significant difference(P<0.001). After TCP, the visual acuity improved in 2 eyes(6.7%), had no change in 24 eyes(80.0%), decreased in 4 eyes(13.3%). After TCP, the exudation of anterior chamber appeared in 12 eyes(40.0%), hyphema of anterior chamber appeared in 3 eyes(10.0%), vitreous hemorrhage in 1 eye(3.3%), which were all cured after drug treatment.

CONCLUSION: TCP with 810nm laser in treatment of refractory glaucoma has curative effect, can degrade the IOP, lessen ocular pain and with few complications.
