    Cogan's syndrome, a rare condition causing eye and hearing issues, is often linked to systemic vasculitis. While corticosteroids offer limited relief, early surgical intervention for aortic valve disease can be life-saving.

    Area of Science:

    • Ophthalmology
    • Rheumatology
    • Otolaryngology

    Background:

    • Cogan's syndrome is a rare clinical entity characterized by nonsyphilitic interstitial keratitis and vestibuloauditory dysfunction.
    • This review analyzes 53 cases to elucidate the syndrome's underlying causes and clinical course.

    Observation:

    • A significant majority (72%) of patients exhibited an underlying systemic process, frequently vasculitis.
    • Aortic valvular disease, potentially fatal, was present in 10% of cases and amenable to surgical intervention.
    • Other systemic manifestations included congestive heart failure, gastrointestinal hemorrhage, adenopathy, splenomegaly, hypertension, musculoskeletal involvement, and eosinophilia.

    Findings:

    • The clinical course of Cogan's syndrome is highly variable, with durations ranging from months to over 15 years.

  • The minimal five-year survival rate was observed to be 28%.
  • Corticosteroid therapy provided some benefit but had limited efficacy for vestibuloauditory dysfunction symptoms.

    • Implications:

    • Cogan's syndrome often represents a manifestation of a broader systemic disorder.
    • Long-term follow-up is crucial for identifying systemic involvement and guiding management.
    • Surgical intervention for associated aortic valvular disease may improve patient outcomes.
