The purpose of this study is to evaluate the success rate and safety of argon laser photocoagulation as a modality of treatment for symptomatic trichiasis in a Middle Eastern country (Jordan). This simple descriptive study included 54 patients (68 lids) with symptomatic trichiasis. They were treated with argon laser and followed over 8 month period. After topical and infiltration anaesthesia, 30-40 shots of blue-argon laser were directed to the lash root to a depth of 2-3mm. Laser beam variables were: 50-100 μm spot size, 0.3 second duration and 0.50 Watt power. The maximum number of treated lashes per lid was five. Recurrence was defined as regrowth of one or more trichiatic lash. Up to two additional applications with the same laser parameters were done for recurrent trichiasis. The success rate after one treatment session was 61.1% and with up to a total of three sessions, it was 85.2%. The complication rate was 20.6% (14 lids) in the form of mild hypopigmentation in 8 lids and notching in 6 lids. The complication rate was higher among patients treated previously with cryotheray or lid surgery. Argon laser photocoagulation is a safe and effective office procedure for treatment of symptomatic trichiasis.
本研究的目的是评估氩激光光凝术作为中东国家(约旦)有症状倒睫治疗方式的成功率和安全性。这项简单的描述性研究纳入了54例有症状倒睫患者(68只眼睑)。他们接受了氩激光治疗,并随访8个月。在局部和浸润麻醉后,将30 - 40次蓝氩激光照射到睫毛根部,深度为2 - 3毫米。激光束参数为:光斑大小50 - 100微米,持续时间0.3秒,功率0.50瓦。每只眼睑治疗的睫毛最多为5根。复发定义为一根或多根倒睫再生长。对于复发性倒睫,使用相同激光参数最多再进行两次治疗。一次治疗后的成功率为61.1%,总共最多三次治疗后,成功率为85.2%。并发症发生率为20.6%(14只眼睑),表现为8只眼睑轻度色素减退和6只眼睑切迹。在先前接受过冷冻治疗或眼睑手术的患者中,并发症发生率更高。氩激光光凝术是治疗有症状倒睫的一种安全有效的门诊手术。
