Static and dynamic pupillometry data of healthy individuals

Area of Science:

• Ophthalmology and Vision Science
• Human Physiology
• Gerontology

Background:

• Understanding normative pupillary function is essential for diagnosing various ocular and neurological conditions.
• Previous research has indicated potential age-related changes in pupillary characteristics, but comprehensive normative data across different age groups remains limited.

Purpose of the Study:

• To establish normative static and dynamic pupillometry data in a healthy population across diverse age groups.
• To investigate and quantify the specific effects of aging on key pupillometric characteristics.

Main Methods:

• Quantitative pupillometry was performed on 155 healthy participants using an automated system.
• Static measurements included pupil diameter under scotopic, mesopic, and photopic conditions.
• Dynamic measurements assessed pupil response characteristics during light and dark stimuli, including contraction and dilation parameters.

Main Results:

• No significant sex-based differences were observed in static or dynamic pupillometry measurements.
• Age demonstrated moderate inverse correlations with static pupillometric characteristics (e.g., pupil diameter) and dynamic measures like resting diameter, velocity of pupil contraction, and velocity of pupil dilation.
• A moderate positive correlation was found between age and latency of pupil contraction.

Conclusions:

• This study provides valuable, population-specific normative data for static and dynamic pupillometry.
• Age is a significant factor influencing pupillary characteristics, with specific trends observed in pupil size and response times.
• The findings contribute to a better understanding of age-related physiological changes in the visual system.
