Nocardia species are aerobic, rod-shaped, Gram-positive bacteria that are ubiquitous throughout the environment. Nocardia nova has been reported as the second most prevalent Nocardia species. However, reports of ocular and periocular infection caused by this organism are rare. The authors present a case of a 58-year-old woman with a medical history of acquired nasolacrimal duct obstruction of the left eye who underwent a revision dacryocystorhinostomy with silicone stent intubation and developed a surgical site infection that was culture-positive for N. nova . Treatment consisted of removal of the silicone stent and a prolonged course of oral antibiotics, resulting in the patient's full recovery. This is the second reported case of postoperative periocular N. nova infection after dacryocystorhinostomy and silicone stent intubation.
诺卡菌属是需氧、杆状、革兰氏阳性细菌，在整个环境中普遍存在。新星诺卡菌已被报道为第二常见的诺卡菌属菌种。然而，由该病原体引起的眼部和眼周感染的报道很少。作者报告了一例58岁女性病例，该患者有左眼后天性鼻泪管阻塞病史，接受了硅胶支架植入的泪囊鼻腔吻合术翻修术，并发生了手术部位感染，培养结果显示为新星诺卡菌阳性。治疗包括取出硅胶支架和长期口服抗生素疗程，患者最终完全康复。这是第二例报道的泪囊鼻腔吻合术和硅胶支架植入术后眼周新星诺卡菌感染病例。
