Intraocular pressure, systemic blood pressure, and age: a correlational study

Area of Science:

• Ophthalmology
• Cardiology
• Gerontology

Background:

• Intraocular pressure (IOP) and systolic blood pressure (SBP) are key health indicators.
• Age-related changes in cardiovascular and ocular parameters require investigation.

Purpose of the Study:

• To investigate the associations between age, intraocular pressure, and systolic blood pressure.
• To determine the relationship between these physiological parameters in different patient groups.

Main Methods:

• Examined 90 non-glaucomatous, ocular normotensive patients and 142 ocular hypertensive patients.
• Created a stratified group to represent general population's intraocular pressure distribution.
• Analyzed correlations between age, intraocular pressure, and systolic blood pressure.

Main Results:

• Systolic blood pressure showed a positive correlation with age across all groups.
• Intraocular pressure was significantly negatively correlated with systolic blood pressure.
• The apparent association between intraocular pressure and age was explained by systolic blood pressure's influence.

Conclusions:

• Systolic blood pressure is a significant factor associated with age.
• The relationship between intraocular pressure and age is mediated by systolic blood pressure.
• Findings suggest a complex interplay between cardiovascular and ocular health indicators.
