Post-traumatic endophthalmitis
1Department of Ophthalmology, University Hospital, Ghent, Belgium.
Abstract:
In a group of 615 cases of perforating trauma, 25 cases (4%) of proven endophthalmitis were seen. The percentage of Bacillus infections was unusually high compared to other types of endophthalmitis (3.8% for the whole group, 31% for the group with intraocular foreign bodies). Bacillus cases have a very poor outcome and in fact the overall functional results in the post-traumatic endophthalmitis group were poorer than in other categories.
Insights
Traumatic eye injuries can lead to endophthalmitis, an infection inside the eye. Bacillus infections, often linked to intraocular foreign bodies, result in poor visual outcomes.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Trauma Surgery
Background:
- Perforating eye trauma is a significant cause of vision loss.
- Endophthalmitis, an intraocular infection, is a severe complication of ocular trauma.
- Prompt diagnosis and treatment are crucial for managing endophthalmitis.
Purpose of the Study:
- To investigate the incidence and outcomes of endophthalmitis following perforating eye trauma.
- To identify specific microbial patterns, particularly Bacillus species, in post-traumatic endophthalmitis.
- To evaluate the impact of Bacillus infections on visual prognosis.
Main Methods:
- Retrospective analysis of 615 cases with perforating eye trauma.
- Identification and categorization of endophthalmitis cases.
- Microbiological analysis to determine causative agents, with a focus on Bacillus species.
- Assessment of visual outcomes and functional results.
Main Results:
- Endophthalmitis was diagnosed in 25 cases (4%) of perforating trauma.
- Bacillus species accounted for an unusually high proportion of infections (3.8% overall, 31% in cases with intraocular foreign bodies).
- Cases involving Bacillus infections demonstrated significantly poorer visual outcomes compared to other endophthalmitis categories.
Conclusions:
- Post-traumatic endophthalmitis presents a substantial risk of vision impairment.
- Bacillus species represent a particularly virulent pathogen in post-traumatic endophthalmitis, especially when associated with intraocular foreign bodies.
- The poor prognosis associated with Bacillus infections underscores the need for vigilant management and potentially targeted therapeutic strategies.
