Age significantly impacts retinal thickness and optic disc measurements in normal older adults. The Retinal Thickness Analyzer (RTA) revealed age-related changes in perifoveal thickness and optic disc morphology.

Area of Science:

  • Ophthalmology
  • Gerontology
  • Medical Imaging

Background:

  • Normal aging can affect ocular structures.
  • Understanding age-related changes is crucial for differentiating normal variations from disease.
  • The Retinal Thickness Analyzer (RTA) provides quantitative topographic measurements of the posterior pole and optic disc.

Purpose of the Study:

  • To evaluate retinal thickness and optic disc parameters using the RTA glaucoma program in healthy older individuals.
  • To investigate the influence of age on these ocular measurements.

Main Methods:

  • Recruited subjects over 40 years old with no prior eye disease history.
  • Included only individuals with normal clinical ophthalmologic exams and visual field tests (Humphrey Field Analyzer - HFA).

  • Utilized the RTA 'glaucoma full' program (version 4.11B) for topographic measurements in 74 eyes.

    • Main Results:

    • Intraocular pressure (IOP) increased with age and correlated with retinal posterior pole asymmetry.
    • Increasing age correlated with decreased perifoveal minimum thickness.
    • Age was also associated with an increased cup-to-disc area ratio and increased cup area.

    Conclusions:

    • An age effect was observed for specific retinal and optic disc measurements obtained via RTA.
    • These findings highlight the importance of considering age when interpreting RTA-derived parameters in older populations.
