Pediatric endophthalmitis: clinical profile, outcomes, and a proposed protocol.

Purpose: To investigate the clinical profile and visual outcomes of infectious endophthalmitis in children at a single tertiary hospital in France, and propose an evidence-based protocol for management.

Methods: This is a retrospective monocentric study that involved children with a history of endophthalmitis between January 2008 and January 2020. The clinical characteristics, etiology, microbiological spectrum from aqueous/vitreous tab, anatomical and visual outcomes, and management were analyzed. The Fischer and chi-square tests were used in the statistical evaluation.

Results: Twenty-six children were eligible for inclusion. The mean patients age at presentation was 4.2 years (range, 8 days-14.3 years). With regard to etiology, patients were divided into posttraumatic group (n = 7 (26.9%)), postoperative group (n = 15 (57.7%)), endogenous group (n = 3 (11.5%)), and infectious corneal ulcer group (n = 1 (3.9%)). Time-to-onset of symptoms was highest in children ≤ 3 years old and in the postoperative subgroup who had at least one glaucoma procedure. Microbiology results showed growth in 12/26 (46.2%). The most common microorganism identified was Streptococcus pneumoniae (5/12 (41.7%)). The antibiotic regimen varied depending on age, organism, and sensitivities. The final visual outcomes were 20/200 or better in 11/26 (42.3%) eyes, and 13/26 (50.0%) eyes had no light perception. Twelve of twenty-six (46.2%) eyes ended up with phthisis bulbi.

Conclusion: Pediatric endophthalmitis is a rare but devastating condition with poor visual prognosis, requiring prompt recognition and treatment. Despite aggressive management with antibiotics and vitrectomy, the visual prognosis is generally poor. A protocol for management with an adapted systemic antibiotic therapy is proposed in order to improve outcomes.
