Phlyctenular keratoconjunctivitis is a nodular foreign antigen delayed hypersensitivity reaction typically due to staphylococcal protein (but potentially secondary to antigen from a variety of different organisms, eg, mycobacteria and intestinal worms).(1-4) Conjunctival phlyctens are usually mild and transient, but corneal phlyctens can be severe and recurrent.(3,4) The subject of this report is a severe recurrent unilateral corneal case in a child whose stool was positive for Hymenolepsis nana. Following treatment for the intestinal parasite, the child no longer suffered from recurrent ocular surface inflammation.
泡性角结膜炎是一种结节性外来抗原迟发型超敏反应，通常由葡萄球菌蛋白引起（但也可能继发于多种不同生物体的抗原，如分枝杆菌和肠道蠕虫）。（1 - 4）结膜泡疹通常症状轻微且为一过性，但角膜泡疹可能症状严重且反复发作。（3,4）本报告的病例是一名儿童，患有严重复发性单侧角膜病变，其粪便中微小膜壳绦虫检测呈阳性。在对肠道寄生虫进行治疗后，该儿童不再遭受复发性眼表炎症。
