Summary
Penetrating eye trauma with lens disruption significantly increases endophthalmitis risk. Prompt treatment and identifying less virulent organisms improve visual outcomes in posttraumatic endophthalmitis cases.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Posttraumatic endophthalmitis is a severe complication of penetrating ocular trauma.
- Identifying risk factors is crucial for prevention and timely management.
Purpose of the Study:
- To determine clinical characteristics associated with a higher incidence of endophthalmitis following penetrating ocular trauma.
Main Methods:
- Retrospective analysis of 258 patients with penetrating ocular trauma.
- Analysis of 28 patients with culture-proven endophthalmitis.
- Evaluation of clinical variables for association with endophthalmitis risk.
Main Results:
- Endophthalmitis occurred in 5% of patients with penetrating trauma.
- Lens disruption was a statistically significant risk factor for endophthalmitis (univariate and multivariate analysis).
- Lens disruption was present in 86% of culture-proven endophthalmitis cases.
Conclusions:
- Lens disruption is a significant risk factor for posttraumatic endophthalmitis.
- Visual prognosis is better with infections caused by less virulent organisms, such as coagulase-negative staphylococci.
