GlaucomaGlaucoma is a common and important health problem. It is one of the take causes of blindness in Western Society (Hoskins & Kass, 1989). It is responsible for ten per centum of all blindness in the United States and continues to be the second or third most common cause of blindness in the knowledge base (Bunce, Fraser, & Wormald, 1999). It is estimated that two million people in the United States have been diagnosed as having glaucoma. Glaucoma is known to affect about two percent of Caucasians beginning at the season of 40 with an increasing risk of infection for those over the age of 60. This risk is especially high if a member of the family has glaucoma or diabetes. Further, there is a higher risk of a glaucoma diagnosis for African Americans over the age of 40.Glaucoma results from increasing intraocular pressure, pressure inside the eye, which can lead to irreparable ill-use to the retina and the optic nerve, which connects the retina with the back of the brain. Int raocular pressure is determined by the balance between the rate of the aqueous humor production (found between the cornea and the lens) and its fortress to bounce at the angle of the anterior chamber. In most cases, increased resistance to aqueous humor outflow causes elevated intraocular pressure. Lowering intraocular pressure constrains or slows the progress of glaucoma.There are many conditions that individuals may encounter as a result of glaucoma. Chew et al. (1999) found high intraocular pressure or the presence of glaucoma to be an identification for decreased life expectancy. After child modifications were made for risk factors such as age, sex, hypertension, diabetes, cigarette smoking, and body skunk index, which are known to be associated with higher mort... ...
