Management of endophthalmitis with pars plana vitrectomy
Abstract:
Pars plana vitrectomy with intravitreal antibiotics is an effective technique in the treatment of culture-proved endophthalmitis. Best results are obtained when the therapy is instituted early in the course of infection, preferably during the first 36 hours of the onset of symptoms, and when the infective organism is of low virulence. In our 20 cases of culture-proved endophthalmitis 17 eyes (85%) were saved and had some degree of useful vision. Thirteen (65%) eyes had a visual acuity of 20/400 or better. Three eyes (15%) were lost.
Insights
Early pars plana vitrectomy with intravitreal antibiotics effectively treats endophthalmitis, saving 85% of eyes. Prompt treatment within 36 hours and low-virulence organisms yield the best outcomes for vision restoration.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Endophthalmitis is a severe intraocular infection that can lead to vision loss.
- Prompt and effective treatment is crucial for preserving visual function.
Purpose of the Study:
- To evaluate the efficacy of pars plana vitrectomy combined with intravitreal antibiotics in treating culture-proven endophthalmitis.
- To identify factors influencing treatment outcomes.
Main Methods:
- Retrospective analysis of 20 cases of culture-proven endophthalmitis.
- Treatment involved pars plana vitrectomy and intravitreal antibiotic administration.
Main Results:
- Overall, 85% of eyes (17 out of 20) were saved with some useful vision.
- 65% of eyes (13 out of 20) achieved a visual acuity of 20/400 or better.
- 15% of eyes (3 out of 20) were lost despite treatment.
Conclusions:
- Pars plana vitrectomy with intravitreal antibiotics is an effective treatment for endophthalmitis.
- Early intervention, ideally within 36 hours of symptom onset, and low-virulence pathogens correlate with better outcomes.
