Background:
Bacterial eye infections are rare in the neonatal population and usually come from exogenous spread. Eye infection due to Pseudomonas aeruginosa, although uncommon, may be a devastating disease, especially in premature infants.
Methods:
Retrospective review of the clinical chart of a 10-day-old newborn baby with bilateral endogenous Pseudomonas aeruginosa endophthalmitis.
Results:
The patient presented with leukokoria in both eyes 7 days after the onset of severe septicemia due to endophthalmitis in both eyes. The baby received systemic treatment with meropenem and vancomycin, which the cultured bacteria were susceptible to, but the infection progressed. Intravitreal ceftazidime treatment and later vitrectomy could not prevent complete retina detachment and the progressive evolution to phthisis.
Conclusion:
Aggressive therapy including systemic antibiotics, intravitreous antibiotic injection, and vitrectomy could not prevent a poor outcome leading to retinal detachment and blindness in both eyes. A discussion of the treatment options and a review of the literature are also included.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
