Glaucoma Research Paper

The dry form is broken down into three stages; Early, Intermediate, and Advanced (National Eye Institute 3). In the Early stage, people have several small or few medium yellow deposits under the retina called drusen. This stage shows no symptoms or vision loss. During the second stage, Intermediate, more medium or even large deposits happen. As this happens, a blurred spot can develop and more light could be needed for reading. Lastly, in the Advanced stage, a breakdown of light-sensitive cells and tissue causes the blurred spot to enlarge and darken. In this latter stage, facial recognition is unlikely unless the person is extremely close. Either form of Macular Degeneration can only be detected by thorough eye exams. The exam should include visual acuity, which measures sight at varied distance intervals. Also, dilation of the eyes will allow an ophthalmologist to check the retina and optic nerve. An instrument called a Tonometer will measure pressure within the eyes (National Eye Institute 6).

Explanation: This is a case of angle-closure glaucoma. Glaucoma is the second-leading cause of blindness in the U.S. It most often occurs in people over age 40. People at risk for angle-closure glaucoma usually show no symptoms before an attack. Some early symptoms of an attack may include blurred vision, halos, mild headaches or eye pain. People with these symptoms should be checked by their ophthalmologist as soon as possible. An attack of

Glaucoma is a condition that affects the eyes by causing damage to the optic nerve within the eye and it can worsen over time. It’s generally associated with an increase in pressure inside of the eye. More often than not it’s inherited and may not reveal itself until much later in life. The increase in pressure is known as intraocular pressure and can damage the optic nerve that’s responsible for transmitting images to your brain. Sadly, if you fail to recognise that you’re suffering from glaucoma and neglect to have it treated, then the damage to the optic nerve from high pressure can become permanent resulting in permanent vision loss. Without treatment, glaucoma can and will result in total and irreversible blindness within a

“Glaucoma damage is permanent—it cannot be reversed. But medicine and surgery help to stop further damage” (Boyd). When starting treatment factors such as optic nerve damage, visual loss, and elevated eye pressure are deciding factors in what type of treatment will be necessary. The most common way to treat glaucoma is eye drops. The way the eye drops work is they either slow down the production of fluid that is created by the eye or they increase the amount of fluid in the eye to help it drain out of the eye. If a person is prescribed eye drops to use for his or her treatment they will usually be applied four times a day. With any type of medication there comes the side effects; In this case, glaucoma eye drops can help lower blood pressure while lowering the pressure in your eyes. The reason the eye drops are able to do this is because they have an element in them called a Beta-Blocker which is a drug that is used to keep the heart in a normal rhythm for people who have fast or irregular heartbeats. Although the best way for someone to prevent this sight-taking disease is to have regular checkups with an ophthalmologist. The doctor will be able to check the eye pressure and determine if it is in normal range. Also, the doctor will be able to actually look into the back of the eye to see if any damage has occurred to the optic

Severe headache, nausea and vomiting, pain in the eye, blurred vision, halo shapes around lights, and eye redness are the main symptoms. These symptoms can all lead to total blindness, because glaucoma can be caught too late. To diagnose if you have glaucoma, the doctors will measuring intraocular pressure, test for optic nerve damage, check for areas of vision loss, measuring corneal thickness, and/or inspect the drainage angle. The main goal in treating glaucoma is to lower the pressure in your eye. Medicines or medications to help may include, eye drops, orla medication, or surgery. Surgery is very common such as lasik eye surgery, in which a doctor will use a laser beam to unclog channels, filtering surgery, where your the surgeon create an opening in the sclera and removes part of the trabecular meshwork, drainage tubes, small tubes that drain fluid, and electrocautery, procedure to take out tissue from the trabecular meshwork using a small device. Some ways to prevent glaucoma are simple at home remedies. These remedies are ones you can do day to day to increase your health and to make sure glaucoma does not happen to you. These include: a healthy diet, regular daily exercise, little to no caffeine, plenty of fluids, sleeping with an elevated head, and taking prescribed

As it was stated before cataracts can lead to Glaucoma. Aqueous humor that would normally drain out the eye, through the junction of the cornea and sclera into the blood stream, is being blocked by the free-floating cataract, yet the production of the aqueous humor is still maintained (Smith). Glaucoma is the increased eye pressure that develops from this continuous buildup of aqueous humor within the eye. Untreated, this can cause permanent blindness, and enlargement of the eye. Glaucoma is also common is dog and cats, yet even with advanced medical and surgical treatments, many of them will lose their eye

Some may or may not know what is narrow angle glaucoma is. NAG (Narrow angle glaucoma) is the most common form of glaucoma which is due to severe eye pain which increases the pressure in the eye. The watery fluid circulates through the eye and drains out the eye in an angle, between the cornea (the window of the eye) and the iris (the colored part of the eye) the slit drain at an angle, which prevent inadequate drainage and causes the pressure in the eye to build up. An attack of this type of glaucoma is an emergency.

Your eye care professional applies a numbing drop to your eye and uses an ultrasonic wave instrument to measure the thickness of your cornea.

Laser treatments can be considered an intermediate step between drug therapy and surgery for patients with glaucoma. Glaucoma is an eye disease which causes damage to the optic nerve fibers and consequently can lead to progressive vision loss or blindness if left untreated. The ciliary body in the human eye is constantly making aqueous humor providing sustenance to surrounding tissues and in order to maintain a healthy balance of this fluid it must leave the eye through the meshwork drainage system along the periphery of the iris. However, if too much aqueous humor is being produced or if the drainage system is not working properly, intraocular pressure builds, in turn causing optic nerve fibre damage and deterioration of vision. The main treatment for glaucoma is topical eye drops, but when a patient is on maximum eye

Furthermore, a research conducted by Harizman et al. (2006) suggested that the inferior, superior, nasal and temporal (ISNT) rule is a helpful method in the diagnosis of glaucoma and risk evaluation during practice. Based on this rule, it is thought that the inferior rim is always thicker than the superior rim followed by nasal rim and lastly the temporal rim is the thinnest (Bourne, 2006).

Glaucoma is the name given to a group of eye diseases that causes damage to the optic nerve fibers and can lead to progressive vision loss or blindness if left untreated. The damage is primarily a result of the buildup of intraocular pressure, which results when an imbalance occurs in the production and drainage of aqueous humour. In the human eye the ciliary body constantly creates aqueous humour to provide sustenance for surrounding tissues. To maintain a healthy balance as new fluid is produced, older fluid must leave the eye through the meshwork drainage system along the periphery of the iris. If too much aqueous humour is produced or the drainage system is not working properly, intraocular pressure builds, causing optic nerve fibre damage and deterioration of vision.

Your optometrist examines your eyes in a number of ways during an exam. One method is the slit lamp test. This is where your eye is examined with a slit of bright light that allows the optometrist to see small sections of the front of your eye in an illuminated state. Abnormalities of your lens can be detected in this way. He or she will also use an ophthalmoscope to brighten and magnify the structures of your eye to check for indications of cataracts. In the case of very advanced cataracts, the cloudy lens is clearly visible without the use of instruments because the lens of the eye takes on a milky appearance.

This condition is usually diagnosed by a health care provider who specializes in eye diseases (ophthalmologist). The ophthalmologist will do a complete eye exam. You may have tests, such as:

When you have a full eye exam, the eye doctor can pick up on evidence of glaucoma as well as other eye diseases. By doing a visual inspection of the inside of your eye with a special scope and light, the doctor can look for damage to your optic nerve, health of your cornea, and condition of the drainage channels in your eyes. To further check for glaucoma, the doctor will test the pressure in your eyes. All these tests are easy to undergo and painless. In addition to the eye tests, your doctor will also check your field of vision for blind spots since glaucoma often causes loss of peripheral vision. With the results of all these tests, your eye doctor can determine if you have glaucoma and tell how

Right now, although there is no way to prevent glaucoma, there are many successful treatments available to prevent the blindness caused by glaucoma. Because the gradual vision loss of chronic glaucoma may not be noticed until it is too late, regular eye examinations, dilated exams of the optic nerve, and screening tests of the visual field are essential for all persons aged 40 and older, especially is your family has a history of glaucoma.
