Abstract

Purpose : The clinical interpretation of IOP has been complicated due to intra-individual variation comprising diurnal and seasonal components. We tried to better understand seasonal variation of IOP based on health screening data of healthy Korean subjects linked with the climate records related to the time point of each measurement.

Methods : Healthy adults who visited CMC health check-up center and underwent tonometry exam were included. All available IOP results taken between March 2, 2015 and February 28, 2017 were retrospectively reviewed. Seasonal climate information and patients’ IOP information of 41,062 eyes were obtained. The patients were classified into 4 groups based on their age and sex.

Results : Seasons at the measurement of IOP had significant influence on IOP after adjusting for other variables for all groups. Atmospheric temperature showed negative correlation with the average IOP, while atmospheric pressure positively correlated with average IOP.

Conclusions : IOP is affected by temperature and atmospheric pressure, and as such, shows seasonal variability. This variability is believed to be caused by related factors such as hematological factors.

Figure 2. Seasonal variation of IOP and climate factors. From left-side to right-side, the association between IOP and atmospheric temperature, atmospheric pressure, relative humidity, and sun exposure time are depicted. IOP is represented by bars and climate factors by lines: atmospheric temperature, red line; atmospheric pressure, green line; relative humidity, blue line; sun exposure time, orange line.
