Post-operative trichiasis (PTT) is a major challenge following corrective eyelid surgery for trachomatous trichiasis. There is a scarcity of research on post-operative trichiasis in Southern Ethiopia, particularly in the study area. This study aimed to assess the prevalence of post-operative trichiasis in patients who underwent corrective surgery.
To assess the prevalence of post-operative trichiasis in the Gamo Zone in Southern Ethiopia in 2021.
A descriptive community-based cross-sectional study was conducted in the Dita district, Southern Ethiopia. The data were collected between 2014 and 2020. Three Qualified trachoma trichiasis (TT) graders working on a trachoma impact survey were recruited for this study. Eye examinations were performed by graders on all study subjects using a loupe to identify post-operative trichiasis. All patients underwent upper eyelid surgery only. A systematic sampling technique was used to select 459 participants from the TT Surgery Logbook.
Of the 459 study participants, more than three quarter 353 (76.9%) were female. The mean age of the study subjects was 48.38 years with a standard deviation of +-10.4. A total of 10 upper eyelids (7 bilateral and 3 left upper eyelids) underwent PTT. The prevalence of post-operative trichiasis in the study area was 2.2% (95% CI: 0.9-3.5%. Fourteen (4.7%) unoperated upper eyelids developed trichiasis infection. A few patients had left and right lower eyelid trichiasis (6/459 [1.3%] and 3/459 [0.7%], respectively).
The prevalence of post-operative trichiasis in the study area was similar to that recommended by the World Health Organization (WHO) recommendation range. Trachoma trichiasis was observed on the lower and upper unoperated eyelids of the study participants. Therefore, sustainable interventions should be considered in the study area for all the components of the SAFE strategy, particularly on S component.
术后倒睫是沙眼性倒睫矫正眼睑手术后的一项重大挑战。在埃塞俄比亚南部，尤其是在研究区域，关于术后倒睫的研究稀缺。本研究旨在评估接受矫正手术患者的术后倒睫患病率。
评估2021年埃塞俄比亚南部加莫地区术后倒睫的患病率。
在埃塞俄比亚南部的迪塔区开展了一项基于社区的描述性横断面研究。数据收集于2014年至2020年期间。招募了三名从事沙眼影响调查的合格沙眼性倒睫（TT）分级员参与本研究。分级员使用放大镜对所有研究对象进行眼部检查，以确定术后倒睫情况。所有患者仅接受了上睑手术。采用系统抽样技术从TT手术日志中选取459名参与者。
在459名研究参与者中，超过四分之三即353名（76.9%）为女性。研究对象的平均年龄为48.38岁，标准差为±10.4。共有10只上睑（7例双侧和3例左上睑）出现术后倒睫。研究区域术后倒睫的患病率为2.2%（95%置信区间：0.9 - 3.5%）。14只（4.7%）未手术的上睑发生了倒睫感染。少数患者出现左、右下睑倒睫（分别为6/459 [1.3%]和3/459 [0.7%]）。
研究区域术后倒睫的患病率与世界卫生组织（WHO）推荐范围相似。在研究参与者未手术的上下眼睑中观察到了沙眼性倒睫。因此，应在研究区域针对SAFE策略的所有组成部分，特别是S部分，考虑采取可持续的干预措施。
