    Prompt treatment of bacterial and fungal endophthalmitis with intravitreal antibiotics and vitrectomy improves visual acuity. Early intervention within 36 hours and less virulent organisms correlate with better outcomes in endophthalmitis cases.

    Area of Science:

    • Ophthalmology
    • Infectious Diseases

    Background:

    • Endophthalmitis, a severe intraocular infection, poses a significant threat to vision.
    • Prompt diagnosis and treatment are crucial for preserving visual function.

    Purpose of the Study:

    • To evaluate the efficacy of intravitreal antibiotics and vitrectomy in treating bacterial and fungal endophthalmitis.
    • To identify factors influencing treatment outcomes in endophthalmitis.

    Main Methods:

    • Laboratory evaluation of nontoxic intravitreal antibiotic doses.
    • Treatment of 26 endophthalmitis cases using intravitreal antibiotics or vitrectomy.
    • Analysis of visual acuity outcomes, time to treatment, and organism virulence.

    Main Results:

    Related Experiment Videos

  • 46% of patients achieved visual acuity better than 20/100.
  • 27% had visual acuity from light perception to 20/300; 4% had no light perception.
  • 23% of cases required enucleation or evisceration.
  • Optimal results were associated with treatment initiation within 36 hours and less virulent organisms.

    • Conclusions:

    • Intravitreal antibiotics, combined with timely vitreous sampling for culture, are recommended.
    • Vitrectomy 24 hours after initial treatment is advised if cultures are positive.
    • Primary vitrectomy with intravitreal antibiotics is advocated for severe bacterial endophthalmitis and fungal endophthalmitis.
