激光消融与机械拔除治疗倒睫的对比研究

目的:通过对比研究激光消融与机械拔除治疗少量倒睫的疗效,探讨激光治疗少量倒睫的疗效和安全性。方法:选取59例80眼少于10根倒睫的患者,将患者倒睫按鼻、颞侧平均分两区,随机对鼻、颞两区内倒睫进行激光消融或机械拔除治疗。记录观察鼻、颞两区术后眼部刺激症状,以及睑缘小凹、皮肤色素脱失、倒睫复发等。如复发,继续采用原治疗方法治疗,共观察6mo。结果:激光消融治疗倒睫一次治疗成功率62.1%,两次治疗成功率88.9%。机械拔除治疗区一次治疗成功率5.3%,两次治疗成功率8.2%,由于复发率高,两次治疗后改激光消融治疗。激光治疗无术后红肿以及睑缘小凹、皮肤色素脱失。结论:机械拔除治疗倒睫复发率高,而激光消融治疗复发率低,并发症少,是一种治疗少量倒睫的理想方法。

A contrastive study of laser ablation and mechanicalepilation in treating trichiasis

AIM: To probe the effect and safety of laser ablation for minor trichiasis through the contrastive study on the effect of laser ablation and mechanical epilation in trichiasis.

METHODS: Totally 59 cases(80 eyes)of minor trichiasis(less than 10)patients were involved. The phalangosis was divided into two areas according to the patient's nasal side and bitamporal and then were practiced laser ablation and mechanical epilation to them. Post-operative stimulating sign of the two areas, eyelid fovea, skin depigmentation and trichiasis recurrence were recorded and observed. Traditional treatment was practiced to those trichiasis recurrences and they were observed for half a year.

RESULTS: The success rate of first-time laser ablation intrichiasis was 62.1% and second-time treatment was up to 88.9%, while for the mechanical epilation in trichiasis it was 5.3% and 8.2% respectively. Because of its high reoccurrence rate, after two times of mechanical epilation in trichiasis, the patients received laser ablation. After receiving laser ablation, there were no red and swollen sign, no eyelid fovea and no skin depigmentation.

CONCLUSION:Mechanical epilation has a high recurrence rate in trichiasis while laser ablation has a much lower recurrence rate and has much less complications. So laser ablation is an ideal treatment for the minor trichiasis.
