The aim of this study was to find concrete clinical evidence for determination of the best method of treatment for trichiasis and the location that responds best to treatment with radiofrequency and argon laser.
This study was performed in 2007 and 2008 on 100 patients, involving a total of 1,181 lashes in contact with the globe. Patients were randomly assigned to 2 groups of treatment: the radiofrequency group (group 1; 2 watts, 2- to 3-mm depth, cut-coagulating mode) and the argon laser group (group 2; spot size 50 μm, 760 mW, 930-nm wavelengths, continuous). After complete ophthalmic examination and photography, the eyelid was divided into 3 segments (medial, central, and lateral) and treated. The patients were examined 3 months later in terms of response to treatment, pain, and complications.
The mean age of the patients was 57.1 ± 24, ranging from 14 to 98 years. Of the 100 patients included, 56% were women and 44% were men. The results revealed the successful treatment of 472 (82.4%) lashes in the radiofrequency group and 383 (62.9%) in the argon laser group. Responses were significant in the central regions of the upper and lower lids (p = 0.001). Similarly, notching was observed in 4 cases, 3 of which (75%) belonged to the radiofrequency group. However, this trend was not statistically significant.
The radiofrequency method was found to be superior in comparison to argon laser in the central regions of both upper and lower eyelids.
本研究旨在寻找治疗倒睫的最佳方法的具体临床证据，并确定射频和氩激光治疗效果最佳的位置。
本研究于 2007 年至 2008 年在 100 例患者中进行，共涉及 1181 根与眼球接触的睫毛。患者被随机分为两组进行治疗：射频组（第 1 组；2 瓦，2-3 毫米深度，切割凝固模式）和氩激光组（第 2 组；光斑大小 50μm，760mW，930nm 波长，连续）。在完成全面的眼科检查和摄影后，将眼睑分为 3 个部分（内侧、中央和外侧）进行治疗。3 个月后，对患者的治疗反应、疼痛和并发症进行检查。
患者的平均年龄为 57.1±24 岁，年龄范围为 14 至 98 岁。100 例患者中，女性占 56%，男性占 44%。结果显示，射频组成功治疗了 472 根（82.4%）睫毛，氩激光组成功治疗了 383 根（62.9%）睫毛。在上、下眼睑的中央区域，射频组的治疗效果明显优于氩激光组（p=0.001）。同样，观察到 4 例出现切迹，其中 3 例（75%）属于射频组。然而，这种趋势没有统计学意义。
与氩激光相比，射频方法在上、下眼睑的中央区域更具优势。
