Conjunctival lymphangiectasia is an uncommon clinical condition in which there is dilatation of lymphatic channels in the bulbar conjunctiva. Conjunctival lymphangiectasia is a rarely appreciated ocular surface disorder that typically occurs as a secondary phenomenon in response to local lymphatic scarring or distal obstruction. Conjunctival lymphangiectasia can either be unilateral or bilateral with focal or diffuse bulbar chemosis. We present 11 cases of biopsy-proven conjunctival lymphangiectasia. Of the 11 cases, 3 presented with bilateral diffuse bulbar chemosis, 1 had diffuse unilateral chemosis, and the remaining 7 presented with focal (<90°) bulbar chemosis. Three of these cases had co-existing pterygium, and one case presented with focal bulbar chemosis and a conjunctival keratin horn. All underwent surgical excision of the involved conjunctiva, either with no graft (n = 6), combined with amniotic membrane transplant (n = 3), or combined with conjunctival autograft (n = 2).
结膜淋巴管扩张症是一种不常见的临床病症，其特征是球结膜淋巴管扩张。结膜淋巴管扩张症是一种很少被认识到的眼表面疾病，通常作为局部淋巴管瘢痕或远端阻塞的继发现象发生。结膜淋巴管扩张症可以是单侧或双侧的，表现为局灶性或弥漫性球结膜水肿。我们报告了 11 例经活检证实的结膜淋巴管扩张症。在这 11 例中，3 例表现为双侧弥漫性球结膜水肿，1 例表现为弥漫性单侧球结膜水肿，其余 7 例表现为局灶性（<90°）球结膜水肿。其中 3 例伴有共存的翼状胬肉，1 例表现为局灶性球结膜水肿和结膜角化棘皮瘤。所有患者均接受受累结膜的手术切除，其中 6 例未行移植，3 例联合羊膜移植，2 例联合结膜自体移植。
