Diagnosis
Glaucoma is diagnosed by an ophthalmologist through a comprehensive eye exam that includes a visual acuity test, which measures the eyesight at various distances; a visual field test to measure the peripheral vision; tonometry, to measure the pressure inside the eye; dilated eye exam for examining the retina and optic nerve for signs of damage by putting special dilatory eye-drops in the eye; and by pachymetry, measurement of the thickness of the cornea by using an ultrasonic wave instrument. ("Glaucoma" National Eye Institute, "How is Glaucoma Detected?")
Treatment
Treatment for glaucoma is aimed at slowing the damage to the optic nerve. In adults, the eyesight already lost cannot be reversed while in children with congenital glaucoma some reversal is possible. Most treatments consist of lowering of the pressure in the eye (the intraocular pressure) through medication, laser treatment, or conventional surgery.
The treatment is usually started with medicines, i.e., eye drops or pills that either cause the eye to make less fluid or lower pressure by...
Marijuana Should Not Be Legalized Physical Health Concerns According to a Harvard University Law School document, it would be "…fallacious to conclude that because the chemicals in marijuana have been found to present fewer dangers…" than cocaine, heroin, alcohol and tobacco, that the recreational use of marijuana "is safe" (Harvard). In fact, even though many states authorize the use of cannabis for medical purposes (for AIDS sufferers and for those experiencing harmful
Target Group and their Local Government To determine the actual effects of diabetes on the indigenous population, you must examine the areas where many of these individuals live. This will provide insights as to possible issues that could be contributing to the problem by: examining the policies of the local government, looking at relevant health statistics, determining fruit / vegetable consumption and looking at the different support services / infrastructure. These
LEADING CAUSES OF MORBIDITY: Some of the diseases which often result in early death in African-Americans, provided that the go untreated or undiagnosed, include hypertension, coronary heart disease, stroke, kidney failure, dementia (i.e., Alzheimer's disease), diabetes and certain types of cancer, most notably lung cancer, breast cancer, colon cancer and prostate cancer (in men). Exactly why the morbidity rates for these disease are so much higher in African-Americans than in other

Even though users of light therapy are often advised not to look directly at the light source, the mechanisms of the eye focus incoming light onto the macula, the small region of the retina where vision takes place, and where age-related macular degeneration occurs. Since blue light wavelength make up only a small percentage of the light in white light, any form of light therapy using a high proportion
1958 After studying the cardiovascular effects of various catecholamines, Moran and his research partner, Perkins, are published in the same journal as Ahlquist arguing "that DCI's activity belonged to Ahlquist's 'beta-adrenergic' type, and coined the term 'beta-adrenergic blocking drug', later shortened to 'beta-blocker'" 1959 Sir James Black joins the cardiovascular team at Imperial Chemical Industries, Ltd., reads Moran's research and realizes the possibilities of synthesizing an analog to DCI that would be clinically
