Acinetobacter baumannii Endogenous Endophthalmitis Presenting with Iris Nodules.

Aim: We report a unique finding of iris nodules in a woman with endogenous endophthalmitis due to Acinetobacter baumannii with no history of ocular surgery or trauma and good visual outcome.

Materials & methods: Retrospective case report.

Results: A 39-year-old woman with a history of type 2 diabetes mellitus presented with a decrease in vision in the right eye of 1-month duration. On examination, her BCVA was CF2m (OD) and 6/6 (OS). Right eye examination showed medium-to-large-sized keratic precipitates, iris nodules, and vitritis. PCR on the aqueous showed faint positivity for Propionibacterium acne and was negative to panfungal genome. Despite two intravitreal injections of vancomycin (1 mg/0.1 ml) and intravenous cefazolin 1 g bd for 5 days, there was progression to hypopyon. Vitrectomy with lensectomy was done. The vitreous culture grew Acinetobacter baumannii. She was given multiple intravitreal ceftazidime (2.25 mg/0.1 ml) with dexamethasone (0.4 mg/0.1 ml) injections. She was also put on tab bactrim DS twice a day for 3 months along with tab doxycycline 100 mg twice a day for 3 months by the infectious disease specialist. As the inflammation improved, the iris nodules were the last to resolve completely in 6 weeks. At 15-month follow-up, her eye was quiet, and vision was 6/9 (OD) with aphakic correction.

Conclusion: We report a rare finding of iris nodules in a patient with culture proven Acinetobacter baumannii endogenous endophthalmitis.
