Patients with keratoconus exhibit higher rates of psychological abnormality compared to controls. Factors like prior surgery and perceived vision limitation significantly influence these personality trait scores.

Area of Science:

  • Ophthalmology
  • Psychology
  • Corneal Diseases

Background:

  • Keratoconus is a progressive corneal condition affecting vision.
  • The psychological impact of chronic eye diseases is increasingly recognized.
  • Previous studies have not extensively explored personality traits in keratoconus patients.

Purpose of the Study:

  • To investigate and compare personality traits between keratoconus patients and a control group.
  • To identify psychological differences using the Minnesota Multiphasic Personality Inventory (MMPI).
  • To explore factors influencing psychological abnormality scores in keratoconus.

Main Methods:

  • A controlled prospective study design was employed.
  • Participants included patients with keratoconus and a control group with herpes simplex keratitis.

  • The Minnesota Multiphasic Personality Inventory (MMPI) was administered to assess personality traits.

    • Main Results:

    • A significantly higher percentage of keratoconus patients (54%) showed scores indicative of psychological abnormality compared to controls (25%).
    • Unoperated keratoconus patients had a higher rate of abnormal MMPI scores (63%) than those who underwent penetrating keratoplasty (33%).
    • Patients reporting moderate to severe vision limitation were more likely to have abnormal scores (87%) than those with mild limitations (40%).

    Conclusions:

    • Keratoconus is associated with a greater prevalence of psychological abnormalities.
    • Penetrating keratoplasty may be associated with improved psychological profiles in keratoconus patients.
    • The perceived severity of vision impairment significantly correlates with psychological well-being in keratoconus.
