Endogenous endophthalmitis is a rare ocular infection affecting the vitreous and/or aqueous humours. It is associated with poor visual prognosis and its commonest endogenous aetiology is infective endocarditis. The causative organisms of endogenous endophthalmitis complicating endocarditis are mainly Group A or B streptococci. The identification of Group C and G streptococci such as Streptococcus dysgalactiae is comparatively uncommon and has only been reported in a few case reports or series. We therefore report a case of infective endocarditis caused by Streptococcus dysgalactiae first presenting with endogenous endophthalmitis, the most likely source being osteomyelitis of both feet in a patient with type I diabetes. The patient was treated with a course of intravenous benzylpenicillin, intravitreal antibiotics, bilateral below knee amputations and mitral valve replacement. She survived all surgical procedures and regained partial visual acuity in the affected eye.
内源性眼内炎是一种罕见的眼部感染，累及玻璃体和/或房水。它与不良的视力预后相关，其最常见的内源性病因是感染性心内膜炎。并发心内膜炎的内源性眼内炎的致病微生物主要是A组或B组链球菌。C组和G组链球菌如停乳链球菌的鉴定相对少见，仅在少数病例报告或系列报道中出现。因此，我们报告一例由停乳链球菌引起的感染性心内膜炎，最初表现为内源性眼内炎，最可能的来源是一名I型糖尿病患者的双脚骨髓炎。患者接受了一个疗程的静脉注射苄星青霉素、玻璃体内注射抗生素、双侧膝下截肢和二尖瓣置换术治疗。她挺过了所有手术，患眼恢复了部分视力。
