Glaucoma eye drops can make a world of difference in daily pain maintenance, when used as prescribed by your physician. Fluid pressure of the eye (intraocular pressure, or IOP) can build up so high that it exceeds the optic nerve’s tolerance, resulting in glaucoma. Most typically, glaucoma shows up in people age 40 or older, although the subtlety of its presence can unfortunately go undetected for some time. Thus, having the “puff of air” standard glaucoma test in addition to your regular eye exam is wise, especially for this age demographic. Glaucoma eye drops are a popular treatment choice for primary open angle glaucoma, the most common form of the disease.
