There has been no published investigation into the reasons why some patients with severe trachomatous conjunctival scarring develop entropion and trichiasis while others do not. In a population of leprosy patients with severe trachomatous conjunctival scarring the authors found that lagophthalmos correlated with the absence of trichiasis and entropion. We suggest that orbicularis oculi muscle function, as well as other anatomical variations among individuals, may contribute to the development of trachomatous entropion and trichiasis in patients with conjunctival scarring.
对于一些患有严重沙眼性结膜瘢痕的患者为何会出现睑内翻和倒睫而另一些患者却不会，目前尚无已发表的相关研究。在一群患有严重沙眼性结膜瘢痕的麻风病患者中，作者发现兔眼症与无倒睫和睑内翻相关。我们认为眼轮匝肌功能以及个体间的其他解剖学差异，可能在结膜瘢痕患者沙眼性睑内翻和倒睫的发生中起作用。
