    Essential iris atrophies can cause corneal edema and glaucoma. Lowering intraocular pressure often relieves edema, and penetrating keratoplasty is effective when other treatments fail.

    Area of Science:

    • Ophthalmology
    • Corneal Diseases
    • Glaucoma

    Background:

    • Essential iris atrophies are a group of conditions affecting the iris.
    • Corneal edema and secondary glaucoma are potential complications.

    Observation:

    • A clinical study observed 90 patients with essential iris atrophies.
    • Corneal edema was present in 54% of patients.
    • A distinct hammered-silver appearance of the posterior cornea was noted in 54 cases.

    Findings:

    • Intraocular pressure varied from normal to extremely elevated, causing glaucomatous damage.
    • Reducing intraocular pressure successfully relieved corneal edema in many patients.
    • Electron microscopy of keratoplasty specimens showed abnormal posterior corneal cells.

    Implications:

    • Management of intraocular pressure is crucial for patients with essential iris atrophies.
    • Penetrating keratoplasty offers a viable treatment option for refractory corneal edema.
    • Further research into the abnormal posterior corneal cells may elucidate disease mechanisms.
