Argon激光治疗复发性倒睫24眼(英文)

Argon laser photocoagulation for 24 eyes of recurrent trichiasis

目的:评价氩激光治疗复发性倒睫的疗效和安全性。方法:Argon激光治疗18例(24眼)复发性倒睫,光斑50～200μm,时间0.25～0.5s,能量400～800mW。部分倒睫用美蓝染色后治疗。治疗全过程无需麻醉,平均随访时间6.12mo。结果:经过1～4次氩激光治疗,其中83.33%痊愈。刺激症状消失或明显减轻。激光治疗次数与倒睫数量间明显相关。治疗6wk后所有患者无睑缘畸形和新生血管形成。结论:氩激光治疗复发性倒睫较其他治疗方法安全、有效、简便、副作用小。

AIM: To evaluate the efficacy and safety of Argon laser microsurgery for the treatment of recurrent trichiasis.· METHODS: A total of 24 eyes (18 patients) with aberrant lashes were treated. Each lash was treated with a beam of 50-200 μm (spot size), 0.25-0.5s (time), and 400-800mW(power). Some ingrowing lashes were dyed in methylene blue before the treatment. No anaesthetic was used for the procedure. The mean follow-up time was 6.12 months.· RESULTS: Successful treatment with no evidence of recurrence was achieved in 83.3% eyes after one to four laser sessions. Irritating symptoms of all patients disappeared or were obviously relieved after treatment. There was a significant correlation between the number of aberrant lashes per eye and the number of required laser sessions. Complete healing of the treated area occurred within six weeks after the procedure, with no vascularization or distortion of the lid margin.· CONCLUSION: Argon laser treatment appears to be a quick, simple and convenient, safe and effective alternative to the other recognized methods in selected cases.·
