Cataract Research Paper

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

Eyes are very essential part of your life and you should take all the essential steps to maintain it. Regularly visiting your eye doctor will certify that your eyes are in good condition and will detect any signs of severe disease.

Other factors include family history, medical conditions, which include diabetes, high blood pressure, heart conditions and physical injury of the eye. Other eye-related risk factors are eye anatomy, corneal thickness and optic nerve appearance. Conditions such as retinal detachment, eye tumors, and eye inflammations, high amounts of nearsightedness may also induce glaucoma.

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.

Macular Degeneration is a disease that affects the retina of the eye. The retina is a layer in the back of the eye that helps us to see. It is also the lining of the eye that helps us respond to light. However, when having macular degeneration there are major changes in a person's central vision. The disease causes central images to appear blurred and then dark spots may begin to appear that get larger and larger. It may also be very hard to see straight lines as Macular Degeneration may cause them to be curved. When having this disease color may appear to be darker and less vivid than normal.

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

Eye color comes from the amount of melanin, a pigment found in the front part of the iris of the eye (Genetics, 2017). Lack of melanin results in blue eyes, some melanin gives green eyes, and a lot of melanin gives brown eyes. Cataracts are clouding of the lens that prevents light from entering. The cause of cataracts is unknown but there are possible reasons for it such as diabetes, smoking, and a lot of exposure to sunlight. Signs include lack of color intensity, night vision problems, fuzzy, blurry, or filmy vision. The function of the retina is to receive light the lens had focused on, switch the light into neural signals, and then send those signals to the brain for visual recognition. Most of the time eye floaters are from age related

These cataracts could have formed due to the smoking which introduces toxins or hypertension from the artery occlusion. As the tight junctions lose their structure from the atherosclerosis and the toxins within the blood, they allow in insoluble proteins with disulfide bonds which results in different size and weight structures decreasing the uniformity within the lens (Shambhu and Diwan 1984). The main flaw to this causation would be the singularity in that both oculus unitas would have cataracts in most cases, hence the cataract must be mostly onset by the ocular ischemic

You may not be expecting for your eye doctor to say "You have cataracts." If that happens to you, rest assured that modern cataract surgery can usually restore the vision you have lost. In fact, it can often reduce your need for eyeglasses.

Secondary cataract. Cataracts can also be result of a surgery of other eye problems like glaucoma. It can also be a result of other health problems like diabetes.

Diabetes is among the leading causes of irreparable blindness all over the world. In the U.S., it is the most typical cause of blindness to individuals below the age of 65 years. Moreover, diabetic eye disease circumscribes extensive issues that can infect the eye. The diabetic disease known as retinopathy is the utmost cause of low vision and new blindness cases in adults between the ages 20 and 65 years.

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. However, some glaucoma is not distinguished by high intraocular pressure, but as optic nerve damage. 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, consequently intraocular pressure builds, causing optic nerve fiber damage and deterioration of vision.

Advancing age is a common hindrance to the proper functioning of the body senses. The eyes will have difficulty focusing on near and distant objects. Adapting to different levels of light is the other common problem. Cataracts, also called clouding of vision is another common condition that results from changes in eye’s lens. Hearing abilities also diminish. With this, you will have difficulties following a conversation or hearing high frequencies.

Furthermore, another part of the eye affected by ultraviolet radiation is the lens and the eye disease in this part is a cataract, which cataract disease is caused by degeneration of the lens and symptoms with a blurred vision as a fog, hindering the light to pass into the eyes and the optic nerves are fully. The treatment of cataract disease is surgery to remove the Natural lens and then insert the intraocular lens to replace, also after cataract surgery, patients should take care of themselves, eat a healthy meal and the most important thing is to avoid sunlight.
