Acute corneal calcification.

S E Bloomfield, D S David, A L Rubin

    Annals of Ophthalmology
    |March 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Uremic patients can experience acute corneal calcification due to high calcium-phosphorus levels and corneal exposure. Prompt removal involves chelating agents and massage to clear dense calcium deposits.

    Area of Science:

    • Ophthalmology
    • Nephrology
    • Biochemistry

    Background:

    • Corneal calcification is a rare but serious condition.
    • Uremia is associated with metabolic disturbances, including altered calcium and phosphorus levels.
    • Corneal exposure can compromise the ocular surface and predispose to injury.

    Observation:

    • A case report details acute unilateral calcium deposition in the central cornea.
    • The affected patient had uremia and corneal exposure.
    • The calcification was rapid and dense.

    Findings:

    • A high calcium-phosphorus product is implicated in the rapid calcification.
    • Local factors from corneal epithelial cell injury likely contributed.
    • Successful removal required constant irrigation with a chelating agent and vigorous massage.

    Implications:

    • This case highlights a potential ocular complication in uremic patients.
    • Understanding the mechanism can inform preventative strategies.
    • Effective treatment involves specific chelating agents and mechanical removal techniques.
