The relationship between body temperature and intraocular pressure
Annals of Ophthalmology
|February 1, 1981
Summary
This study compared intraocular pressure (IOP) in acclimatized and nonacclimatized individuals in heat. Results suggest a direct relationship between IOP and body temperature, specifically rectal temperature.
Area of Science:
- Environmental Physiology
- Ocular Physiology
Background:
- Intraocular pressure (IOP) regulation is complex.
- Environmental factors like heat can influence physiological parameters.
Purpose of the Study:
- To investigate the relationship between intraocular pressure (IOP) and body temperature.
- To compare IOP in acclimatized versus nonacclimatized individuals under heat stress.
Main Methods:
- Subjects were well-hydrated during submaximal workload in a hot environment.
- Intraocular pressure (IOP) was measured and compared between acclimatized and nonacclimatized groups.
- Rectal temperature was used as a proxy for core body temperature.
Main Results:
- A direct relationship between intraocular pressure (IOP) and rectal temperature was observed.
- This suggests body temperature is a significant factor influencing IOP in hot environments.
Conclusions:
- Body temperature, indicated by rectal temperature, is postulated to directly influence intraocular pressure (IOP).
- Further research is warranted to elucidate the mechanisms linking thermoregulation and ocular hemodynamics.
