Eye changes after forty.

I A Abrahamson

    American Family Physician
    |April 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    After age 40, the eye lens loses elasticity, causing presbyopia. Other common age-related changes include xanthelasmas, entropion, ectropion, blepharochalasis, glaucoma, and cataracts.

    Area of Science:

    • Ophthalmology
    • Geriatric Medicine
    • Oculoplastics

    Background:

    • Aging significantly impacts ocular structures, with common changes occurring after age 40.
    • Loss of tissue elasticity is a primary factor in several age-related eye conditions.

    Purpose of the Study:

    • To outline common age-related ocular changes after 40.
    • To differentiate between normal physiologic changes and conditions with increased frequency.

    Main Methods:

    • Review of common age-related ocular conditions.
    • Description of the pathophysiology of eyelid laxity and lens changes.

    Main Results:

    • Presbyopia, resulting from lens inelasticity, is the most frequent physiologic change.

  • Xanthelasmas, entropion, ectropion, and blepharochalasis are common, often linked to eyelid tissue laxity.
  • Glaucoma and cataracts, while not normal, increase in incidence with age.

    • Conclusions:

    • Ocular changes after 40 range from normal physiologic shifts like presbyopia to conditions requiring intervention.
    • Understanding these changes is crucial for appropriate management and patient counseling.
