Research Paper On Cataracts

A cataract range broadly in terms of severity, it means that some patients can live normally without treatment while others need serious medical treatment. A cataract has two stages: early stage and advance stage. Moreover, stages classified based on how risky they are and how they affect the vision. In the early stage, most patients notice a few symptoms appear in their sight. Vision becomes slightly blurred, double vision sight –also known as diplopia- and night vision deteriorates. Early stage of cataract does not develop rapidly, and it may never raise large enough to become a problem. This stage of cataract should be recognized and treated to avoid the serious development. However, in many cases cataract becomes gradually worse and increase

See the eye doctor. An ophthalmologist can check you for diabetes-related eye disease. Not everyone with diabetes develops vision problems, but most are very treatable and catching them early helps.

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.

Your family doctor or pediatrician may make a referral to an eye doctor for more complete evaluation when eye problems are suspected by during routine physical

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).

This condition begins in the childhood or teenage years, from ages 8 to 14. When the eyeballs can't have light rays focused on the front of its retina, then, nearsightedness happens. Even if treatment cannot change the course of this condition, it is important to have this detected as early as possible. Many people with perfect vision may tend to take their eye health for granted. The eyes are our ticket to the visual world. Can you imagine yourself living in a world of darkness? It's very easy to neglect your eyes and here's a list on how you can keep it healthy. Six Ways in Having Healthy Eyes 1. Have a Consultation It's important to have your eye checked each year to see if you have any vision problems. Don't ignore headaches as they may be a sign of vision problems. Also, make sure you get the right type of eyeglasses or contact lenses since using the wrong one can affect your eye health. 2. Use Sunglasses We put sun block on our skin, but we forget to put protection on our eyes. Use sunglasses with UV protection since your eye sight can easily deteriorate with too much sun exposure. Darker lenses don't really guarantee better protection. You need to check the level of protection by getting a high category number on your sunnies ( 4 is the best ). Even if the sky is cloudy, wear your sunglasses. 3. Eat Healthy You are what you eat and there are foods

My inspiration for wanting to become an optometrist was jump-started by my aunt Rosemary. My aunt suffers from dry macular degeneration, and she first started losing her eyesight when I was about five years old. I have always been close to her, and I have seen her vision deteriorate. Today she can see peripherally. I have watched as she lost her driving privileges and was forced into an early retirement. I always viewed my aunt's condition without an appreciation of how lucky I truly was to have normal vision. However, In the summer of 2002 I visited an optometrist for the first time. Since that first visit to the optometrist 13 years ago, my eyesight has drastically deteriorated. I currently have a correction factor of -7.25 in my right eye, and a correction factor of -8.0 in my left eye. My vision has stabilized, but my high correction power, coupled with observing my aunt's macular degeneration, allowed me to understand that the gift of vision may not be an everlasting gift. I want to do my best to help people make the best of what may not be an enduring attribute of their lives.

The study has been conducted for the past twenty years. It found that among the 74,044 women who are 65 and older that all of them who had cataracts, 60 percent lower risk of death among the 41,735 women who did get them removed. Cataracts happen over time from age and most people end up having to get the surgery. The study show that because of the surgery it reduced people's risk of death from multiple health issues. Cataract surgery is probably the most successful surgery around because it is done so

“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.

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

Cataracts: As people age, proteins can gradually build up on the lens, causing a brownish or yellowish tint to the lens, blocking effective light transfer to the retina. Other things can cause the lens to lose it's clarity, include past eye surgery, injury or damage to the eye and chronic illnesses like diabetes. While more than 50% of Americans will either be living with a cataract or will have had surgery by the time they reach 80 years of age, even adults in their forties and fifties develop cataracts, and some babies are born with cataracts. Symptoms – cloudy vision, trouble driving at night, struggling to find a vision prescription that works well – gradually worsen over time. Surgery is currently the only therapeutic option.

This depends on how early or late patients are willing to receive a diagnosis from ophthalmologists. In early treatments, glaucoma is not curable, but there are methods to control its progression or to prevent the increased risk of blindness. What ophthalmologists aim for in treating this disease is decreasing intraocular pressure in one’s eye. Determined by the condition the patients are in, “options may include eye drops, laser treatment, or surgery.” The Prevent Blindness America Organization plays an extensive role in projecting awareness for glaucoma and in helping those to fight against it. They “conduct mass glaucoma screenings” and list possible medications such as beta-blockers and carbonic anhydrase inhibitors. These are used to decrease the quantity of aqueous fluid in the eye (Marks and Montauredes

Do you know what the leading cause of blindness is in Americans from ages 20 to 74? It is diabetes an illness that changes the way the body breaks down and absorbs sugars. These changes, doctors feel, take away oxygen that the retina needs. (The retina is the back layer of the eye and it is where sharp images are formed.) When this happens’ some small blood vessels may become weak and break, vision problems occur when this blood leaks into the areas around the retina. Diabetes can also cause glaucoma and cataracts. Glaucoma is a disease that causes a lot of pressure in the eye because too much fluid builds up. Cataracts, on the other hand, cloud the lens of the eye and this makes a person feel like he or she is looking through a grimy window.

Diagnosis includes a testing of the three senses. A vision test is needed along with a retinal examination to evaluate structures in the back of your eye and retina. An electroretinogram will

Acute glaucoma must be treated early to prevent loss of vision. Treatment usually begins with laser treatment to make a new opening in the iris that allows the angle to open. This is often restores vision, but in some eyes it is necessary to use eyedrops long-term. Surgical treatment
