Summary
Obesity is linked to higher intraocular pressure (IOP), a key factor in glaucoma. This study confirms obesity as an independent risk factor for increased IOP in a large Japanese population.
Area of Science:
- Ophthalmology
- Public Health
- Epidemiology
Background:
- Previous studies suggest a link between obesity and intraocular pressure (IOP).
- Longitudinal data on this association are limited.
- This study investigates the relationship between IOP and obesity in a large Japanese cohort.
Purpose of the Study:
- To evaluate the association between intraocular pressure and obesity.
- To conduct both cross-sectional and longitudinal analyses.
- To determine if obesity is an independent risk factor for elevated IOP.
Main Methods:
- Retrospective review of annual health examinations (1989-1997).
- Cross-sectional analysis of 70,139 individuals (aged 14-94).
- Longitudinal analysis of 25,216 individuals with >3 IOP measurements, examining changes in IOP and weight.
Main Results:
- Cross-sectional: Body Mass Index (BMI) significantly correlated with IOP after controlling for age, gender, and blood pressure.
- Longitudinal: Changes in weight were significantly associated with changes in IOP, even after adjusting for covariates.
- IOP decreased with age and was higher in males than females.
Conclusions:
- Obesity is significantly associated with intraocular pressure (IOP) in both cross-sectional and longitudinal analyses.
- Findings indicate that obesity is an independent risk factor for increased IOP.
- This highlights the importance of weight management in eye health.
