For eye pressures, a value of 28 hPa (21 mmHg) above atmospheric pressure 1,010 hPa (760 mmHg) is often used, with higher pressures leading to a greater risk. [2] [26] However, some may have high eye pressure for years and never develop damage. [2] Conversely, optic nerve damage may occur with normal pressure, known as normal-tension glaucoma. [27]
