Abstract
Purpose: To identify the microbiological spectrum and visual outcome of exogenous infectious endophthalmitis in the pediatric age group. Methods: We reviewed the medical records of all children 14 years and younger with culture-positive endophthalmitis treated at King Khaled Eye Specialist Hospital and King Abdulaziz University Hospital between January 1, 1980, and December 31, 2004. Results: Forty-nine children were identified. There were 32 males and 17 females with a mean age of 5.7 ± 2.8 years (range 1–13 years). Thirty-five (71.4 %) cases occurred after penetrating open globe injuries and the remaining 14 (28.6%) followed ocular surgery. Primary vitrectomy was performed on 29 (59.2%) eyes. The mean follow-up was 28.4 ± 28.4 months (range 1.2–98.5 months). A single species was isolated in 42 (85.7%) eyes, and multiple organisms in seven (14.3%) with a total of 56 infecting organisms. The most common isolates were Streptococcus species and coagulase-negative Staphylococci comprising 44.6% and 21.4% of the isolates, respectively. Final visual acuity was 20/200 or better in 15 (34.1%), counting fingers in 8 (18.2%), light perception to hand motions in 8 (18.2%), no light perception in 13 (29.5%) eyes, including 3 that have been enucleated or eviscerated, and not available in 5 patients. None of the children who had nonvirulent organisms had a final visual acuity of no light perception compared with 39.4% of children who had virulent organisms (p = 0.011). Visual outcome of counting fingers was attained in 26% of children who were treated with primary vitrectomy compared with 5.9% of children treated with antibiotics alone on presentation (p = 0.0484). Visual outcome was no light perception in 18.5% of children who underwent primary vitrectomy compared with 47.1% of children treated with antibiotics alone. Conclusions: The most common organisms identified were Streptococcus species and coagulase-negative Staphylococci. Culture of a nonvirulent organism, and treatment with primary vitrectomy were associated with better visual outcomes. Visual outcomes were generally poor.
