Bilateral endogenous endophthalmitis caused by HACEK microorganism.
OBJECTIVE
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.
