    Postoperative glaucoma occurred in 30% of eyes after vitrectomy for vitreous hemorrhage, primarily due to ghost cells obstructing the trabecular meshwork. Prevention involves thorough vitreous cavity irrigation during surgery.

    Area of Science:

    • Ophthalmology
    • Glaucoma Research
    • Surgical Complications

    Background:

    • Vitrectomy is a common surgical procedure for vitreous hemorrhage.
    • Postoperative complications can impact visual outcomes.
    • Understanding the causes of secondary glaucoma is crucial for patient management.

    Observation:

    • Six of 20 eyes (30%) developed postoperative glaucoma within 2-10 days after closed vitrectomy.
    • Elevated intraocular pressure (IOP) exceeding 40 mm Hg was observed in all affected eyes.
    • Three eyes required anterior chamber irrigation for pressure control.

    Findings:

    • The primary cause of glaucoma was identified as ghost cell obstruction of the trabecular meshwork.
    • Ghost cells, degenerated red blood cells, were identifiable via phase-contrast microscopy.

  • Three non-glaucomatous eyes showed anterior chamber cellular accumulation.

    • Implications:

    • Thorough irrigation of the vitreous cavity during vitrectomy may prevent ghost cell glaucoma.
    • Early identification and management of ghost cell glaucoma are essential.
    • Distinguishing ghost cell glaucoma from hemolytic glaucoma is important for treatment strategies.
