Cataracts Research Paper

The cataracts within the eye often changes in the lens of the eye. As people grow older the lens in the eye starts to change and can start to appear cloudy looking, this often happens and stops the process of the eye lens from being able to change shape or even to transmit the light properly. The cataracts may start to form between the ages of 50 and 60 years old and can often take a while to develop. If you are known to have diabetes then that also contributes to poor cataracts.

“The doctors told me that cataracts is when the lens of your eye gets cloudy and that is why I couldn’t see,” Matthew said.

“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

Cataracts are an opacity, or cloudy, change in the lens of the eye. This cloudiness prevents

Within this essay I will write about elderly patients, undergoing cataract surgery, as a particular vulnerable client group. The local Health Board (2014) define cataracts as the clouding of the lens, occurring as a natural part of the ageing process, preventing light from adequately reaching the retina and therefore having an effect on vision. This can be corrected through the surgical process of Phacoemulsification, through which the clouded portions of the lens are removed and replaced with an artificial implant (Local Health Board, 2014). Whilst it is common for cataracts to develop as a result of old age, they can also occur as the result of injury, inflammation, degenerative disease, or from the prolonged use of medication. It is also possible for children to be born with cataracts.

Signs/Symptoms: The way a person would know if they have Glaucoma, an eye disease that can make someone go blind, is by looking for the signs or symptoms. Symptoms of Open Angle Glaucoma are patchy blindness spots in the peripheral or central vision and “tunnel” vision in both eyes. The symptoms for Acute Angle-Closure Glaucoma are, as said by Glaucoma - Symptoms and Causes by The Mayo Clinic “eye pain, nausea and vomiting, blurred vision, “halos” around lights - which may be rainbow,” red eyes, and sudden sight loss. The symptoms of this kind of Glaucoma have no typical early warning signs. This is the reason people don’t notice it until it is too late, and they end up losing their vision if it is not treated.

The damage caused by glaucoma can't be reversed. But treatment and regular checkups can help slow or prevent vision loss. The goal of glaucoma treatment is to lower pressure in your eye. Depending on your situation, your options may include eye drops, laser treatment or surgery.

The main way light is obstructed on its way to the retinal is by a cataract in the lens, which is the case in this patient. These can form two major ways: ultraviolet light damage and aging. Ultraviolet light damage leads to an abundance of free radicals. These free radicals act on the crystalline proteins and cause them to clump together, creating a cataract.[2] Another way cataracts are formed is by the natural process of aging. Concentrations of alpha crystallins fall off with age with leads the other subtypes to aggregate and form scleroses (cataracts).[3] This is what is leading to the glare that the patient sees at night. The cataract is scattering the light entering her eye and leading to blur on the retina. Both of these could have contributed to the cataracts in this patient due to her being over 65 and due to her age naturally being exposed to more

Due to the strong genetic component associated with the development of cataracts, there are differences in the incidence and progression of cataracts between races.x White Americans maintain the highest prevalence rate of cataracts (18%), followed by black Americans (13%), and Hispanic Americans (12%). Among all Americans with cataracts, 80% were white, 8% were black, and 7% were Hispanic.4

Cataracts: Cataracts are overcast territories that cover piece of or the whole lens inside the eye. In a solid eye, the lens is clear like a cam lens; light has no issue going through it to the back of the eye to the retina where pictures are handled. At the point when a cataract is introduce, the light can't traverse the lens as effortlessly and, therefore, vision can be disabled. Cataracts frequently shape gradually, without agony, redness, or tearing in the eye. Some stay little and don't adjust visual perception. On the off chance that they get to be huge or thick, cataracts can generally be uprooted by

Cataract is a medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision. It si a common condition in people older than 40 and it is the primary cause of blindness in the world.

Soothing effect on the nervous system, applied to those who have lost understanding and knowledge, sick headache, for those who hide their worries behind a brave face, for those under work-related tension and problems between employer and employee. For stress incontinence.

More specifically 22pter-q11. Cat Eye Syndrome is not necessarily an inherited disorder. It is acquired during a mutation of an egg or a sperm cell. And a person that has CES also has the chance of passing it on to their children although it is usually only passed down from carriers. As WebMD says, “Cat eye syndrome can't be cured because it's caused by a permanent change to a chromosome. But many of the symptoms can be treated.” (“What is Cat Eye Syndrome - Treatment” 2016). For some people who have minor symptoms, surgery will be an option. Anal atresia is fixed with surgery when a baby is born, heart defects and cleft lips also require surgery. Because Cat Eye Syndrome has many symptoms and not everyone has every symptom, a CES patient would have to talk to a medical professional for each symptom they have. Include people who specialize in the eye, digestive, and heart problems. Another useful treatment is counseling, people with CES could benefit greatly learning about how the condition affects them and patients who want to have children should talk to genetic councilors as well. Since CES can also affect childhood development, social skills and education specialist would help children living with CES. The cat eye associated with Cat Eye Syndrome is one of the symptoms that cannot be

     Really the cause of Macular Degeneration is unknown. Recently researchers have discovered that a group of genes called ABCR contribute to the disease. When someone has these genes the likeliness of this person to form Macular Degeneration increases by 30 percent. In most situations Macular Degeneration is

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.
