Aging significantly impacts the blood-aqueous barrier function. Increased aqueous flare intensity, a marker of barrier function, correlates with older age in healthy individuals.

Area of Science:

  • Ophthalmology
  • Gerontology
  • Physiology

Background:

  • The blood-aqueous barrier (BAB) maintains ocular homeostasis.
  • Age-related changes in ocular tissues are common.
  • Understanding BAB function in aging is crucial for eye health.

Purpose of the Study:

  • To investigate the influence of aging on blood-aqueous barrier function.
  • To quantify age-related changes in aqueous flare intensity.

Main Methods:

  • Utilized a laser flare-cell meter to measure aqueous flare intensity.
  • Assessed 203 healthy human subjects across a wide age range (20-79 years).

Main Results:

  • A significant positive correlation was found between age and aqueous flare intensity (r=0.502, P=0.00).

  • Subjects in their 6th, 7th, and 8th decades showed significantly higher flare intensity compared to those in their 3rd decade (P<0.01).

    • Conclusions:

    • Aging negatively affects blood-aqueous barrier function.
    • Increased aqueous flare intensity is a quantifiable indicator of age-related BAB dysfunction.
