Coat's病的光凝与冷凝治疗(附35例报告)

Photocoagulation and Scleral Cryotherapy for Coat's Disease

目的:评价氩激光光凝配合巩膜外冷凝方法在临床上治疗Coat's病的效果及意义。方法:22例23眼用氩激光(德国欧波同Mediek CLu40 E氩离子激光机,能量0.2w,光斑100～500μ,脉冲时间0.1～0.2秒,Ⅱ级反应)或配合巩膜外冷凝(-60～-80℃,冷凝时间5秒,随后重复一次,见视网膜有灰白色水肿反应为宜)治疗。结果:有18只眼获得了不同程度的疗效(治疗有效率占治疗眼数的78.2％)。眼底病变好转或稳定,视力有提高,随访时间1—3年。结论:氩激光或配合巩膜外冷凝方法治疗Coat's病的效果是肯定的。一经诊断为Coat's病,只要患眼有一定的视功能,就应该及时给予光凝或光凝加巩膜外冷凝治疗,这对于防止病情进一步恶化,保存患眼一定的视功能具有重要意义。眼科学报1996;12:199～201。

Purpose: To evaluate the results and significance of Chat' s disease with argon laser photoco-agulation and cryotherapy. Methods :22 patients (23 eyes) were treated by argon laser (German Opton Meditek 40 E, 0.2w power, 100 - 500um spot, 0.1-0.2 second exposure and grade II reaction) and or scleral cryotherapy ( - 60—-80℃,5 second duration per time, repeating treatment if necessary until pale edema was seen in retina). Results: 18 eyes in all (78.2% ) had good results with visual acuity improvement and the lesion of fundus had been seen decreased in varient degrees. The follow - up ranged from 1 to 3 years. Conclusion: Photocoagulation and scleral cryotherapy are effective for those patients with Coat's disease. It is very importent to treat them promptly so as to prevent the damage of visual function progressively. Eye Science 1996; 12:199 - 201.
