Glaucoma Essay

Glaucoma is an eye disorder that cause severe blindness. There are multiple types of Glaucoma however, they all have something to do with damage to the optic nerve (usually form high eye pressure) that sends and receives information to the brain form the eye. Glaucoma can be a very dangerous disease although it is no fatal but it can contribute to the failure of one of the bodies most important senses which is blindness. In most cases, glaucoma is correlated with high pressure inside the eye (ocular

Glaucoma is a group of eye diseases characterized by increased intraocular pressure, resulting in atrophy of the optic nerve. (Venes, D. 2013) This disease is known to gradually cause the loss of peripheral vision which can eventually lead to total blindness. Glaucoma is the third most prevalent cause of visual impairment and blindness in the U.S, although the incidence of blindness is decreasing due to early detection and treatment. (Venes, D. 2013) Glaucoma comes in two major categories: closed-angle

"Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time". (WebMD) Glaucoma is interlinked with the pressure in the eye. No one knows the exact cause of the glaucoma. Doctors think the main cause of the glaucoma is the pressure in the eye. Some people with the normal eye pressure also suffer with glaucoma. There are different kinds of glaucoma such as open angle glaucoma, Angle closure glaucoma, Normal tension glaucoma, Congenital and infantile glaucoma, and

How does the human eye work? The cornea is clear and at the front of the eye. When light rays enter it, the cornea refracts it through the pupil and then the iris. The iris controls how much light may pass through the pupil by expanding or shrinking. Next, the light ray will enter the lens. This also refracts light by changing its shape with the help of the ciliary muscles and the suspensory ligaments. The light will go through a dense jelly-like tissue named the vitreous humour and eventually focused

Patients with OSA have been shown to have a higher incidence of significant systemic conditions such as hypertension, cerebrovascular accident, myocardial infarction, arrhythmias, diabetes, and dementia. Some of the eye problems linked to OSA include glaucoma/other optic neuropathies, retinal vein occlusions, central serous retinopathy (CSR), papilledema/idiopathic intracranial hypertension (IIH), floppy eyelid syndrome (FES), and corneal disorders (i.e. keratoconus). This provides optometrists and ophthalmologists

court ruled in favor of the defendants arguing that in ophthalmology it was not a standard of profession to perform routine glaucoma tests in patients under forty years of age. It is important to note here that the standards of the profession did require performing pressure tests if the patient’s complaints and symptoms indicated that the patient may be suffering from glaucoma. The defendants’ argument was that the test was given thirty days after the patients first complained of visual field problems

Expert Review of Ophthalmology, 5(2), 217-224. doi: http://dx.doi.org/10.1586/eop.10.21 The authors of this article are elaborating on some of the most specifics studies to identify Primary Open-Angle Glaucoma (POAG). Raustenstrauss and Mardin explain how genetics in the family is the main cause for this disease. Although the disease can be mostly genetic heritance, the disease can be difficult to detect on juveniles

Pathophysiology: Dementia Dementia, also known as Alzheimer’s disease (AD), is a progressive, chronic, and degenerative. 60% of dementia occurs in people over the age of 65. Dementia causes loss of judgment, memory, change in personality, and visuospatial perception. Severe cognitive impairment can occur over time, as well as physical deterioration and death. The brain changes in size and weight as a person ages. There is also a narrowing of the gyri, enlargement of the ventricles, and widening

I. Affecting an estimated 10 million people in the US alone, blindness is a disorder of the eyes and the visual centers of the brain, resulting in cloudy to no vision. Even though it is believed that the blind see nothing but darkness, only about three percent of the blind report seeing nothing. Being able to see movement and light is what 97% if the blind report seeing. Even though they are able to see light and movement, they are not able to see color. This is what they are able to see with their

“When I was first diagnosed with glaucoma, I was depressed. I didn’t know much about glaucoma, or whether the pressure could be controlled. I had trouble even accepting that something this serious could happen to my eyes.”- Roger McGuinn, Co-founder of the famed pop music group The Byrds. With no treatment needed, glaucoma is a leading cause of blindness in the United States, while simultaneously being the number one leading cause in Africa (Glaucoma Research Foundation). According to the American
