Science Daily | A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, research from the Emory/Georgia Tech Predictive Health Institute has found.
Prescription medicines to lower the pressure inside the eye (intraocular pressure, or IOP) are used to treat all types of glaucoma. They work either by reducing the amount of fluid (aqueous humor) that is produced by the eye or by increasing the amount of fluid that drains out of the eye. These medicines may be given as eyedrops, as pills, in liquid form by mouth, or through a vein (in emergency situations). In most cases, eyedrops are used first. In congenital glaucoma, medicines may be used to decrease the pressure in the eyes and reduce the cloudiness of the clear front surface (cornea) of the child's eye. Medicines are usually only used until surgery can be done.
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.
