The aging effect on intraocular pressure in an apparently normal population

|June 1, 1984
Summary
Intraocular pressure (IOP) decreases with age but increases with obesity and high blood pressure. Young, obese, hypertensive individuals have the highest IOP, while older, lean, hypotensive individuals have the lowest.
Area of Science:
- Ophthalmology
- Public Health
- Gerontology
Background:
- Intraocular pressure (IOP) is a critical factor in eye health.
- Understanding demographic influences on IOP is essential for preventative care.
Purpose of the Study:
- To analyze the relationship between age, obesity, systolic blood pressure, and intraocular pressure in a large healthy population.
- To identify key factors influencing IOP variations across different demographic groups.
Main Methods:
- Statistical analysis of intraocular pressure (IOP) data from approximately 200,000 healthy Japanese subjects.
- Utilized Schl øtz and noncontact tonometers for IOP estimation.
- Employed multivariate analysis and sample stratification based on age, obesity index, and systolic blood pressure.
Main Results:
- A consistent decrease in IOP with increasing age was observed in both sexes.
- Obesity, systolic blood pressure, and age were identified as the most significant factors affecting IOP.
- Young, obese, and hypertensive subjects exhibited the highest IOP, whereas old, lean, and hypotensive subjects showed the lowest IOP.
Conclusions:
- IOP is physiologically regulated by a balance between age-related decrease and the age-dependent increases from obesity and systolic hypertension.
- These findings highlight the interplay of lifestyle and physiological factors in maintaining ocular health.
