Weather watches and warnings are issued when potentially hazardous weather is occurring or is forecast for the short term period. Some of those bulletins have been changed on April 8, 2014 and below is a list and definitions of the up-to-date watch and warning.
Measuring Eye Pressure. Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal.When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.High eye pressure alone does not cause glaucoma. However, it is a significant risk factor.hen the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension. High eye pressure alone does not cause glaucoma. However, it is a significant risk factor.
Normal-tension glaucoma (also called low-tension glaucoma) is a unique condition in which optic nerve damage and vision loss have occurred despite a normal pressure inside the eye. Eye pressure, called intraocular pressure (IOP), is measured in millimeters of mercury (mm Hg).Normal eye pressure ranges from 10-21 mm Hg. Most people with glaucoma have IOP of greater than 21 mm Hg; however, in normal-tension glaucoma, people have IOP within the normal range.ormal-tension glaucoma (also called low-tension glaucoma) is a unique condition in which optic nerve damage and vision loss have occurred despite a normal pressure inside the eye.
