PURPOSE: To report a case of bilateral endogenous endophthalmitis caused by a HACEK group organism (Actinobacillus actinomycetemcomitans). METHODS: An 85-year-old Caucasian female presented with bilateral light perception visual acuity, anterior chamber cells, hypopyon, posterior synechiae, and no red reflex. RESULTS: The patient underwent bilateral vitrectomy, with topical, intravitreal, and systemic antibiotics. Vitreous cultures revealed gram-negative cocco bacilli consistent with Actinobacillus actinomycetemcomitans. At final follow-up, visual acuity was 20/25 RE and 20/40 LE. CONCLUSIONS: Prompt diagnosis and treatment of HACEK [Hemophilus sp. (parainfluenzae, aphrophilus, paraphrophilus), Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corodens, and Kingella kingae] group bacterial endophthalmitis can yield good results.
