Surgical vitrectomy for pseudophakic malignant glaucoma.

M G Lynch, R H Brown, R G Michels

    American Journal of Ophthalmology
    |August 15, 1986
    PubMed
    Summary

    Pars plana vitrectomy effectively treated malignant glaucoma following cataract surgery. This surgical approach restored aqueous humor flow, unlike medical or laser treatments, offering a viable solution for complex cases.

    Area of Science:

    • Ophthalmology
    • Glaucoma Research
    • Surgical Interventions

    Background:

    • Cataract extraction with intraocular lens (IOL) implantation is a common procedure.
    • Malignant glaucoma is a rare but serious complication that can occur post-ophthalmic surgery.
    • Standard medical therapies are often ineffective in managing post-surgical malignant glaucoma.

    Observation:

    • Four cases of malignant glaucoma developed after cataract extraction and IOL implantation.
    • Three eyes had posterior chamber IOLs, and one had an anterior chamber IOL.
    • Initial medical management failed to resolve the glaucoma in all affected eyes.

    Findings:

    • Nd-YAG laser disruption of the anterior hyaloid face was attempted in one eye without success.
    • Pars plana vitrectomy (PPV) was performed in all four eyes and successfully reversed the glaucoma.

  • In eyes with posterior chamber IOLs, PPV involved excising portions of the lens capsule and zonules to facilitate aqueous flow without IOL dislocation.

    • Implications:

    • Pars plana vitrectomy is a highly effective treatment for malignant glaucoma post-cataract surgery.
    • This surgical technique can re-establish anterior aqueous humor dynamics, even with IOLs in place.
    • Further research into preventative strategies and optimal surgical timing for this complication is warranted.
