Causes And Consequences Of Blindness

Eye Vision Inc, a long-standing medical device manufacturer, has signed a contract to sell Holland Hospital the Clear View Laser and a two-year separately priced maintenance plan for $1 million and $0.2 million respectively. On a when-and-if available bais, Eye Vision Inc. will provide software updats that is embedded with the Laser to maintainance purchasor. The software has never been sold without Laser for its functional necessity. In this memo, as explained below, we conclude that:

Even though the pictures patients saw that were produced by the artificial eye were way far from being the ideal type to call someone not blind, they did let the patient see clear enough to allow them to recognize faces who they would otherwise not be able to see. This breakthrough in the bionic eyes is going to benefit lots of patients with common blindness, macular degeneration, all which affect around 500,000 people in the USA. “The Argus II—a kind of retinal

List at least three resources you should use to determine the visual and academic ability of a student with a visual impairment.

This supports my claim because it shows that even if you are blind you can get damaged cell replaced by stem cells. Also it show that even with damaged eye cells they can be replaced because stem cells can be programed into any cell in the body.

I went to the Palais de Justice de Montréal and saw, in superior court, the trial of the Crown against Ms.Gardner. The 26 years old woman was arrested 4 years ago for importation and possession of powdered cocaine when she landed at Montréal’s Pierre Elliott Trudeau Airport from Jamaica, where she was on vacation. In the 2 suitcases she was carrying, they found over 30kg of cocaine which was separated between the two suitcases. That would have been equivalent to over thirty thousand doses had it made its way in the streets and its value is estimated from 2.4 to 3.5 million dollars. The reason why she was carrying such a large amount so badly hidden is unclear since the process was close to an end and both parties were just summarizing their evidences. The normal sentence for her

Blindness is a motif that readers see throughout King Lear in many characters such as Lear and Gloucester since they are unable to see the truth. Although blindness in the modern world is defined as not having sight, William Shakespeare tells readers that being able to see does not mean morally and spiritually you can see. Lear’s blindness causes him not to see the treachery behind Goneril and Regan at the beginning of the play which causes him to lose his throne and go mad near the end. Also Gloucester is also blind as he does not see the lies hidden behind the truths that Edmund tells him and later when Cornwall pulls out Gloucester’s eyes, Gloucester is able to see the truths and realizes that Edgar is the legitimate son. Shakespeare shows us throughout King Lear that seeing is more than just through our eyes. The play is centered on true visions and blindness.

Glaucoma can occur without much warning, whether its acute from a accident in which a trauma is issued on the eye, or if it is due to age and heredity. Glaucoma doesn 't discriminate, it is seen in all races and genders. It happens so slowly with age and heredity that you don 't even notice the loss of vision until it is too late, and with acute glaucoma it can be painful with pain that radiates over the face, a headache, nausea, vomiting and seeing colored halos around lights and even blurred vision can be a few symptoms (Ignatavicius & Workman, 2013). Once you start seeing halos, and lose peripheral vision, it may be an indicator that irreversible damage to the optic nerve has happened. In this paper we will discuss the pathophysiology of glaucoma, the types of glaucoma as well as the causes for them. the issues that glaucoma can cause someone, and the treatments and interventions. We will also have a education handout to help better understand how to administer the medication, and the effects it has on the eye.

They must have permission from the health regulators due to genetic engineering being illegal in the United States. Though genetic engineering is currently illegal, the DNA that is being edited by scientists has the potential to cure blindness as the DNA is a mutated gene that causes a blinding disorder. This disorder means proteins are incorrectly “printed” causing the retina to not function appropriately. The scientists at Editas are looking to move forward with this by 2017 even though other scientists believe it is too soon to begin a trial on this. (Knapton)

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 hypertension),but it also can occur when intraocular pressure (IOP) is normal. If left untreated glaucoma first causes peripheral vision loss and eventually leads to total blindness.

As a result of retinal haemorrhages, children can suffer with permanent damage to their vision due to the inflicted injury to the eye or the brain. Scarring of the retina or atrophy of the optic nerve may show up months after the injury, and is frequently irreversible. This can result in the infant suffering with severe vision impairments and even blindness (Blumenthal, 2002).

Specifically, those with macular degeneration can benefit greatly from this new technology that “combines infrared video-projection goggles with a small, wire-free chip implanted inside the retina” which picks up video from the camera on the goggles and sends the video to the brain (1). The author claims that these “retinal implants powered by light could reverse vision loss with simple surgery” meaning that vision loss could be gone forever with the new technology

There exists natural blind spots(BS) in the human retina, a location in the visual field that correspond with the optic disk at the back of the eye, which does not receive visual input due to the lack of photoreceptors there. However, people do not perceive a “hole” in their visual field because the other eye and its corresponding region on the visual field that takes visual stimuli from the same area as the blind spot compensates for the lack of visual stimuli thus the lack of visual field representation there. Dilkes et al patch one of the participant’s eyes to deprive the corresponding area in the retina of the other eye that also receives visual stimuli and excites the same cortical area on the primary visual cortex as the blind spot in

Throughout history, noble kings and powerful leaders have fallen from power due to their blindness towards people they trusted. Novels, such as William Shakespeare’s King Lear convey a similar message. Although blindness is conceived as the lack of sight by many, metaphorically speaking, blindness is the inability to see and interpret the truth due to one’s deceptiveness and lies. In King Lear, Lear’s blindness towards Goneril and Regan, and his arrogance, results in his downfall. Similarly, Gloucester’s blind-eye towards Edmund results in his downfall and ironically, his loss of eye-sight. Shakespeare conveys, through the life and dialogue of Lear and Gloucester,

I was not able to be blind for four hours. However, I tried for over two hours in total darkness. Being familiar with my home I thought this voluntary temporary, blindness is the best place. The feeling of overwhelmed wanted to creep in because I needed to take medications and care for Diamond my dog.

Samuel Butler, an English novelist, said, “A blind man knows he cannot see, and is glad to be led, though it be by a dog; but he that is blind in his understanding, which is the worst blindness of all, believes he sees as the best, and scorns a guide." Blindness is a major theme that recurs throughout Shakespeare’s play, King Lear. Samuel Butler’s quote can be used to describe King Lear, who suffers, not from a lack of physical sight, but from a lack of insight and understanding. Blindness is a factor in his poor judgment. It plays a major role in the bad decisions he makes. It leads to harsh treatment of those closest to him. It is the combination of these consequences of Lear’s failed sight that demonstrate how blindness is a major
