WebThe average IOP was 15.2 ± 2.9 mmHg, ranging from 9 to 27 mmHg. A statistically significant linear relationship was found between IOP and CCT (p < 0.0001). Controlling for age, average keratometry, and mean spherical equivalent, it was found that for every 10 µm change in CCT, measured IOP changed by 0.3 mmHg. WebAlgorithm for women yielded 98,6% of IOP mean within 5 mm Hg of mean GAT IOP and 86% within 3 mm Hg. For men 96.4% of IOP mean was within 5 mm Hg of mean GAT IOP and 84.2% within 3 mm Hg from GAT IOP mean.
