泪小管炎被定义为泪管系统的小管部分的感染。尽管通常表现出临床特征,如泪点,放电,内侧can区发红,它通常被误诊和忽视。在这些患者中,泪点溃疡和组织坏死的存在并不常见。我们报告了一例35岁的女性,有3天的左下眼睑内侧肿胀病史,压痛,和放电。她被发现有左下眼睑弥漫性结膜注射和肿胀,涉及下泪点和白色坏死组织。将患者带到小治疗室,并对坏死组织进行清创术,并采取拭子进行培养和敏感性。由于感染的严重性质,发现泪点开放,近端小管系统脱毛;随后使用莫西沙星和聚维酮碘进行冲洗。病人开始使用全身抗生素,局部抗生素滴眼液,聚维酮碘棒清洁受影响的区域。几天后,微生物学结果显示铜绿假单胞菌感染,患者逐渐好转,直到感染完全消退。
Canaliculitis is defined as infection of the canalicular part of the lacrimal system. Despite usual presenting clinical characteristics such as pouting of the lacrimal punctum, discharge, and redness at the medial canthus area, it is usually misdiagnosed and overlooked. The presence of punctal ulceration and tissue necrosis is an uncommon presentation in these patients. We report a case of a 35-year-old female with a 3-day history of left lower eyelid medial swelling, tenderness, and discharge. She was found to have left lower eyelid diffuse conjunctival injection and swelling involving the lower lacrimal punctum with whitish necrotic tissue. The patient was taken to the minor treatment room and debridement of the necrotic tissue was done and swabs were taken for culture and sensitivity. The punctum was found to be open with deroofing of the proximal canalicular system due to the severe nature of the infection; this was followed by irrigation using moxifloxacin and povidone-iodine. The patient was started on systemic antibiotics, topical antibiotic eye drops, and povidone-iodine sticks to clean the affected area. Few days later, the microbiology results revealed infection by Pseudomonas aeruginosa, and the patient was improving gradually until she had complete resolution of the infection.
