Postvitrectomy keratopathy.

F S Brightbill, F L Myers, G H Bresnick

    American Journal of Ophthalmology
    |May 1, 1978
    PubMed
    Summary

    Pars plana vitrectomy can cause significant corneal complications, including slow healing and keratitis. Careful surgical precautions are essential to minimize these risks in patients undergoing this eye surgery.

    Area of Science:

    • Ophthalmology
    • Surgical Complications
    • Corneal Diseases

    Background:

    • Pars plana vitrectomy is a common intraocular surgery.
    • Corneal complications following vitrectomy can impact visual outcomes.
    • Identifying risk factors is crucial for prevention.

    Purpose of the Study:

    • To determine the incidence of corneal complications after pars plana vitrectomy.
    • To identify predisposing factors for these complications.
    • To suggest measures for minimizing corneal issues.

    Main Methods:

    • Retrospective analysis of 75 eyes undergoing pars plana vitrectomy.
    • Documentation of corneal complications and their treatments.
    • Statistical review of patient factors and surgical variables.

    Main Results:

    • Twenty-six out of 75 eyes (34.7%) developed significant corneal complications.
    • Common complications included epithelial defects, recurrent erosion, and keratitis.
    • Predisposing factors identified: diabetes, surgical trauma (debridement, long operative time), aphakia, and postoperative glaucoma/hyphema.

    Conclusions:

    • Corneal complications are a notable risk after pars plana vitrectomy.
    • Patient comorbidities and surgical techniques significantly influence complication rates.
    • Adherence to careful preoperative and operative protocols can reduce corneal morbidity.
