Distichiasis is a condition clinically presenting as partial or complete accessory row of lashes that emerges from the meibomian glands orifices. It can be an acquired or congenital with an autosomal dominant inheritance. The histopathological features are not well described in the ophthalmic literature, however they include abnormal pilosebaceous units within the posterior lamella of the eyelid and perifollicular chronic inflammatory cell infiltration. In this report, we describe the histopathological findings of three congenital distichiasis cases treated at King Khaled Eye Specialist Hospital (KKESH), Riyadh, Saudi Arabia with discussion on the pathogenesis of such a condition and the differentiating features from ectopic cilia.
双行睫是一种临床上表现为从睑板腺开口处出现部分或完整副睫毛排的病症。它可以是后天获得性的，也可以是常染色体显性遗传的先天性疾病。眼科文献中对其组织病理学特征描述不多，不过这些特征包括眼睑后层内异常的皮脂腺单位以及毛囊周围慢性炎性细胞浸润。在本报告中，我们描述了沙特阿拉伯利雅得国王哈立德眼科专科医院治疗的3例先天性双行睫病例的组织病理学发现，并讨论了该病症的发病机制以及与异位睫的鉴别特征。
