Pars plana vitrectomy in ocular trauma.

S J Ryan, A W Allen

    American Journal of Ophthalmology
    |September 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Pars plana vitrectomy improved vision in 62% of ocular trauma patients. Early intervention within 14 days, ideally 4-10 days post-injury, enhances visual prognosis by preventing complications.

    Area of Science:

    • Ophthalmology
    • Trauma Surgery
    • Regenerative Medicine

    Background:

    • Ocular trauma often leads to severe visual impairment and necessitates enucleation.
    • Intraocular fibrocellular proliferations cause tractional retinal detachment and other complications.
    • Pars plana vitrectomy offers a potential solution for previously inoperable cases.

    Purpose of the Study:

    • To evaluate the efficacy of pars plana vitrectomy in treating ocular trauma.
    • To identify prognostic factors influencing visual recovery after ocular trauma.
    • To determine the optimal timing for vitrectomy in traumatized eyes.

    Main Methods:

    • Retrospective analysis of 100 consecutive patients with ocular trauma.
    • Treatment involved pars plana vitrectomy.

  • Prognostic factors including injury type, location, and timing of surgery were assessed.

    • Main Results:

    • Visual improvement was observed in 62% of patients.
    • Anterior segment injuries had a better prognosis than posterior segment injuries.
    • Vitrectomy within 14 days post-injury, particularly 4-10 days, yielded better visual outcomes.

    Conclusions:

    • Pars plana vitrectomy significantly improves visual recovery in ocular trauma.
    • Early vitrectomy interrupts fibrocellular proliferation and prevents severe sequelae.
    • Optimal timing for vitrectomy is crucial for maximizing visual prognosis in traumatized eyes.
