    Pars plana vitrectomy is effective for severe ocular trauma, with 38% achieving 20/40 vision. Optimal timing for this eye surgery appears to be 15-30 days post-injury for best visual outcomes.

    Area of Science:

    • Ophthalmology
    • Trauma Surgery

    Background:

    • Severe ocular trauma presents significant challenges for vision preservation.
    • Pars plana vitrectomy is a key surgical intervention for managing complex eye injuries.

    Purpose of the Study:

    • To evaluate the long-term visual outcomes of pars plana vitrectomy in severe ocular trauma.
    • To determine the impact of surgical timing and specific injury characteristics on visual prognosis.

    Main Methods:

    • Retrospective analysis of 73 consecutive cases of severe ocular trauma.
    • Management involved pars plana vitrectomy with an average follow-up of 37 months.
    • Analysis of visual acuity based on timing of vitrectomy and presence of blood-lens-vitreous mixing.

    Main Results:

    Related Experiment Videos

    • 38% of eyes achieved a final visual acuity of at least 0.5 (20/40); 69% achieved 0.025 (5/200) or better.
    • Visual outcomes were similar for early (1-14 days) and later vitrectomy (>14 days).
    • Best results were observed with vitrectomy performed 15-30 days post-injury; no adverse effects noted for blood-lens-vitreous mixing or in pediatric patients.

    Conclusions:

    • Pars plana vitrectomy offers favorable visual outcomes in severe ocular trauma.
    • Surgical timing between 15-30 days may optimize results, though early intervention is still beneficial.
    • Factors like blood-lens-vitreous mixing and pediatric age did not negatively impact prognosis in this series.
