532nm激光光凝治疗视网膜前出血的临床观察

目的　探讨５３２ｎｍ激光光凝治疗视网膜前出血的临床疗效。方法　收集我院２０１０年１月至２０１３年１０月确诊为视网膜前出血的患者１３例（１３眼），对其临床资料进行回顾性分析。８眼行激光爆破模式引流失败，改行激光光凝模式治疗；５眼视网膜前出血病程超过２周者直接行激光光凝模式治疗。所有患者均接受视网膜激光光凝模式治疗１～２次，术后随访１个月，观察视力、眼底彩照及并发症情况。结果　接受激光治疗的１３眼患者，６眼（４６．２％）行１次视网膜激光光凝术、７眼（５３８％）行２次视网膜激光光凝术。所有病例经治疗后出血均明显吸收，平均吸收时间１８．９２ｄ；视力都有不同程度提高，１个月后随访视力平均提高６．０行。视网膜前出血吸收后激光光凝处未遗留激光斑痕迹，亦无色素增生，所有病例无其他激光并发症发生。结论　５３２ｎｍ激光光凝模式治疗视网膜前出血简单实用、安全有效，且可重复实施，在激光引流视网膜前出血失败后或对于病程较长者可作为有效治疗手段。

Clinical observation of 532 nm laser photocoagulation for pre-retinal hemorrhage

Objective To explore the clinical efficacy of 532 nm laser photocoagulation for pre-retinal hemorrhage. Methods Thirteen patients ( 13 eyes) with preretinal hemorrhage in our hospital from January 2010 to October 2013 were collected and the clinical data were retrospectively analyzed. A11 13 eyes were treated by 532 nm laser photocoagulation. in which 8 eyes underwent the laser photocoagulation treatment of pre-retinal hemorrhage after the laser incision and drainage of the posterior vitreous cortex had failed,5 eyes with the treatment duration of over 2 weeks directly underwent the laser photocoagulation treatment. All the patients went through the retinal laser photocoagulation once or twice ,the follow-up time was I month .the visions ,fundus photographs and complications were observed. Results Of all the 13 eyes treated by laser, 6 eyes( 46. 2% ) undergone the retinal laser photocoagulation once and 7 eyes ( 53. 8% ) twice. After the treatment the pre-retinal hemorrhage significantly absorbed and the average time of absorbing was 18. 92 days. The vision of all cases improved to varying degrees, the average vision at postoperative I month improved by 6. 0 lines. No photocoagulation spots were left and no pigment proliferation appeared on the laser mark after pre-retinal hemorrhage absorbing. No obvious laser complication was observed in all cases. Conclusion 532 nm laser photocoagulation for pre-retinal hemorrhage is simple , practical, safe and effective. and can be operated repeatedly. It can be used as an effective method after the failure of the laser incision and drainage of the posterior vitreous cortex or in the context of a relatively long duration.
