Cataracts What is a cataract? A cataract is a cloudy or opaque area in the normally transparent lens of the eye. Its effect on vision depends on the extent of the cloudiness. Small spots in the lens may cause little or no vision loss. As the opacity thickens, it prevents light rays from passing through the lens and focusing on the retina, the light sensitive tissue lining the back of the eye. Early lens changes or opacities may not disturb vision. But as the lens continues to change
According to Mayoclinic.org the definition of cataract is a clouding of the normally clear lens of your eye (July 2013). I would like to discuss with you the pathophysiology of this disorder, the causes of this issue as well as some of the effects it can have on you, and some treatment options for those you suffer from this internal eye disorder. A cataract affects the lens of the eye. The lens is generally clear in color, and it is elastic in nature. The lens is surrounded by a capsule like
legumes, breast milk, and many other foods. A test for galactosemia is done at the time of birth with other tests. If left untreated 75% of infants will die. Some effects of having classic galactosemia include: an enlarged liver, kidney failure, cataract, and brain damage. Duarte Galactosemia is the second form. This form is when there is only a partial loss of the enzyme. The activity is usually 25%-50% that of a normal child. A child can get this form of galactosemia by inheriting a classic galactosemia
Blindness When a society goes blind, things begin to change. Things become harder to do with the lack of vision. People 's behaviors change when they are filled with darkness, when they can 't do anything for themselves, and when violence erupts. They start to forget who they are and lose their humanity. They are no longer human, but animals. In "Blindness," Jose Saramago demonstrates how his characters that lack vision act like animals by being brutal, disheveled, and absurd. Instead of
Blindness in Raymond Carver's Cathedral Blindness creates a world of obscurity only to be overcome with guidance from someone willing to become intimate with the blind. Equally true, the perceptions of blindness can only be overcome when the blind allow intimacy with the sighted. Raymond Carver, with his short story Cathedral, illustrates this point through the eyes of a man who will be spending an evening with a blind man, Robert, for the first time. Not only does this man not know Robert
Cathedral by Raymond Carver In Raymond Carver?s ?Cathedral?, the conventional ideas often associated with blindness and sight are challenged. By juxtaposing his two male characters, Carver is able to effectively explore sight and its seemingly simplistic relationship with learning and knowledge. As well, he addresses the barriers imposed by the human tendency to rely on vision as the sole means of experiencing the world. At the beginning of the story, the narrator?s perception on blind
being clouded by cataracts, then choosing the best type of cataract surgery for you is a decision to not take lightly. While there used to be one basic type of cataract removal surgery available, you now have several options that cannot only ensure the best possible surgery outcome, but also make your vision even better after surgery than it was before you even developed cataracts. Read on to find out about these newer options and why they are so groundbreaking. 1. Laser Cataract Removal with 3D
Chapter 29: Introduction to the lens, cataracts and surgery Introduction The human eye is one of the most complex organisms in the human body and the lens is one of the most impressive structures within it! Despite being slightly over two centimeters in diameter, the human eye has over two million moving parts. Sight is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. The lens is a key component of the eye which, coupled with
Cataract is a condition that clouds the lens in the eye that leads to decrease in vision. There are many factors that cause cataract but the most common is aging, blunt trauma can also cause cataracts due to swelling and thickening of the lens fiber. Cataract can also develop after a long and constant exposure to radiation. Genetics can also play a part in developing the condition. Most common symptoms of cataracts are cloudy or blurry vision, colors seems faded, poor night vision, double vision

The purpose of this paper is to determine best practices to assure cataracts patient at Group Health (GHC) are adequately prepared for surgery. Objectives The three objectives for this project are: 1.) Identify best practice by researching current literature on effective methods for providing pre-surgical patient education to the population >65 years old on cataract surgery. 2.) Assess present pre-op education process for cataract patients at GHC to determine current state and whether there are
How Cataract Surgery Improves Your Vision And How It's Done If you have cataracts, you may need surgery at some point in the future. Cataracts grow at different rates, and yours might not need surgery for years. On the other hand, if your cataracts grow quickly and interfere with your vision, then having them removed is the best thing to do. The procedure is fairly simple and quick. It's done as an outpatient at an eye surgery center. Here's a look at how the surgery can help and how it's done.
There are about 2.78 deaths that has been reported to the state. The cataract patients that do not go through surgery has death of 2.98. (Turner 3) The more common cataract surgery is called phacoemulsification. Endophthalmitis is a serious infection inside the eye that can develop after cataract surgery. (Preidt 1) Endophthalmitis after cataract surgery is usually the result of a bacterial
during that period of time have the biggest impact on the person. Evidence of this can be found in the novel Cataract City by Craig Davidson, Barometer Rising by Hugh MacLennan, and through history itself. Paragraph 1 : Firstly, evidence can be found in Cataract City by Craig Davidson, a modern novel that tells the story of two boys, Duncan and Owen, on their lasting friendship in Cataract City, also known as Toronto. The small town is comprised
“The word cataract comes from the Greek word cataractos, which means rapidly running water. When water is turbulent, it is transformed from a clear medium to white and cloudy.” Although the Greeks named cataracts they weren’t sure what caused the clouding they observed but thanks to modern science we are one step closer to understanding. Cataracts are a condition where the lens of the eye, which in healthy people is clear, becomes cloudy due to changes in the proteins that make up the lens of the
Samantha Hutchins 12/8/15 The Optical Lens and Cataracts The optical lenses of the eyes are used to focus light. The light that penetrates the lens is controlled by the iris, which constricts and dilates in response to varying light conditions. Controlling the amount of light that reaches the lens, and subsequently the photoreceptors in the pigmented retina, is not enough to adequately discern images in three dimensions. The lens is therefore responsible for adjusting to conditions based on how
The Implications of Ozone Depletion on Human Health Introduction Hairspray. Refrigerators. Air conditioners. These everyday luxuries, while making human life more comfortable, are taxing our health seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals used in refrigerants and as propellants in aerosols. CFCs, also known as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows harmful ultraviolet rays to reach the Earth and its inhabitants
During my research about my family history. I discovered my parental grandfather was diagnosed with prostate cancer for nearly 10 years before he died of old age. He was a long term smoker and did not have a healthy diet. He was also diagnosed with cataracts for awhile before he received surgery on both eyes to correct the problem. Overall, he lived a long average life and was never overweight or obese. He did not have any heart problems and was not diabetic. Following, my parental grandmother died
Patricia Bath is a very honorable and talented African American who helped bring the gift of eyesight to those who are blind. Her most famous accomplishments include the invention of the Laserphaco Probe, a device used for removing cataracts and her creation of the “Community Ophthalmology”, a new field of study.Thanks to Dr. Bath, there is still hope that people who who are blind can still see. Dr. Patricia Era Bath was born on November 4, 1942 in Harlem, New York to Rupert and Gladys Bath.
and severe sunburns and cataracts. non-melanoma is considered all skin cancer other than melanoma. The most common types are basal cell carcinoma and squamous cell carcinoma. Cataracts is the clouding of the lens that lies behind your iris and pupil. The three most common types include subcapsular, nuclear, and cortical cataracts. Subcapsular cataracts is mostly in the back of the lens. Nuclear cataracts develops in the nucleus of the lens. The last one is cortical cataracts which mostly occurs in
