Risk Factors for Development of Endophthalmitis after Open Globe Injury in Children: A Case-Control Study

To identify risk-factors for developing endophthalmitis following open globe injury (OGI) in children.Retrospective, single-center, case-control study of children aged18 years who sustained OGI.Our cohort of 93 eyes consisted of 30 cases (Group A- endophthalmitis) and 63 controls (Group B- no endophthalmitis). Twenty-four eyes (80%) diagnosed with endophthalmitis presented after 24 hours of injury. The presence of central corneal zone-1 injuries (Odd ratio [OR]: 6.64, p= 0.001) and vitreous in wound (OR: 3.53) were associated with the risk of developing endophthalmitis. (p=0.05) Additionally the presence of iris prolapse (OR: 4.76) and posterior capsular rupture (PCR) (OR: 5.80) increased the risk of developing endophthalmitis.(p0.05) . Streptococci was isolated in 15 eyes, Pseudomonas in 3 eyes, and Candida in 1 eye. The visual outcomes at three months were significantly worse in Group A (LogMAR 1.77±1.06) compared to Group B (LogMAR 0.65±0.68)(p0.05).Central corneal involvement, vitreous/ iris incarceration and PCR were important risk factors for development of PTE in children.
