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.
A normal result means your eye pressure is within the normal range. The normal eye pressure range is 10 to 21 mmHg. The thickness of your cornea can affect measurements. Normal eyes with thick corneas have higher readings, and normal eyes with thin corneas have lower readings. A thin cornea with a high reading may be very abnormal (the actual eye pressure will be higher than shown on the tonometer).
