Ocular tension: comparison between the two eyes.
We have compared IOP values in the two eyes in 13,000 presumably healthy subjects over the age of 40 years. The mean difference in ocular tension between the two eyes was 0.12 mm Hg (higher on the left), which is statistically significant but probably without physiological implications. Individual cases with delta IOP of 3 mm Hg or more were observed more frequently in older age groups and in subjects with elevated IOP values, and should arouse suspicion of incipient glaucoma.
