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.
Hyperosmotic agents reduce IOP by lowering fluid volume in the eye. Usually given only on a one-time, emergency basis, these drugs include oral glycerin and isosorbide orally, and mannitol and urea intravenously. Combination glaucoma drugs.
