The most common form of glaucoma is “open-angle” glaucoma, where the eye pressure or IOP remains higher than normal (typically 8-20 mm Hg). Eye doctors also look at changes in peripheral field typically measured with a visual fields test and any changes in the optic nerve such as optic nerve thinning or increased cupping. Ocular hypertension is diagnosed when IOP is higher than normal but there as no signs of glaucoma. In addition glaucoma can occur without high IOP, “normal or low tension glaucoma.”
The most common treatment for lowering eye pressure is the use of prescription eyedrops which either reduce the amount of aqueous fluid produced or increase the drainage. Often these eyedrops are effective in lowering eye pressure but do have unpleasant side effects for some people.
In some cases, medication can be avoided completely with natural approaches though it is essential that the patient get checked on a regular basis to make sure that the IOP is at recommended levels, and work closely with the eye doctor. Continue reading “Glaucoma, IOP, and Herbal Extracts”
