Keratoglobus and blue sclera

A W Biglan, S I Brown, B L Johnson

    American Journal of Ophthalmology
    |February 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    This study identifies a rare genetic disorder characterized by keratoglobus, joint hypermobility, and hearing loss, inherited in an autosomal-recessive pattern. Affected individuals experience severe eye complications, including corneal perforations and vision loss.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Connective Tissue Diseases

    Background:

    • Describes a rare autosomal-recessive condition affecting multiple systems.
    • Highlights the genetic basis and inheritance pattern of the disorder.

    Observation:

    • Patients presented with keratoglobus, blue scleras, joint hyperflexibility, hearing alterations, and dental mottling.
    • Keratoglobus was present from birth, with corneal perforations occurring after minor trauma.
    • Histopathology revealed extremely thin corneal stroma, absent Bowman's layer, and thickened Descemet's membrane.

    Findings:

    • The condition exhibits an autosomal-recessive inheritance pattern.
    • Severe ocular fragility leads to frequent corneal perforations and potential vision loss.
    • Associated systemic features include joint hypermobility, hearing impairment, and dental anomalies.

    Implications:

    • Understanding this condition aids in early diagnosis and genetic counseling.
    • Further research may reveal therapeutic targets for corneal fragility and other systemic manifestations.
    • This study contributes to the knowledge base of rare genetic connective tissue disorders.
