GlaucomaGlaucoma is a common and important health problem. It is atomic number 53 of the leading causes of blindness in Western Society (Hoskins & Kass, 1989).

I ntraocular mechanical press is determined by the rest between the rate of the aqueous humor production (found between the cornea and the lens) and its resistance to outflow at the angle of the anterior chamber. In most cases, change magnitude 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 chance 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(prenominal) minor modifications were made for risk factors such as age, sex, hypertension, diabetes, cigarette smoking, and clay mass index, which are known to be associated with higher mort... ...
