If only one eye is affected, you may not notice any changes in your vision because your good eye may compensate for the weak eye. And the condition doesn't affect side (peripheral) vision, so it rarely causes total blindness. Dry macular degeneration is one of two types of age-related macular degeneration. It can progress to wet (neovascular) macular degeneration, which is characterized by blood vessels that grow under the retina and leak. The dry type is more common, but it usually progresses slowly (over years).…
Macular degeneration is the deterioration of the central portion of the retina within the eye and affects the images we see. There are two types: wet and dry. Wet macular degeneration is when fluid leaks from blood vessels that develop under the macula. Due to the fluid, photoreceptor cells die or degenerate and the macula rises from its previous position. Vision loss of this form is more aggressive and causes lines to appear wavy and spots to appear in the middle of one’s vision.…
Past Medical & Surgical History, Pathophysiology of medical diagnoses (with APA citations) 1. Iron Deficiency Anemia: The most commonly occuring cause of anemia. Iron deficiency results in the lack of iron for hemoglobin synthesis within the body. This may be a result of low intake, diminished absorption, physiological increase in requirements, excessive iron loss, chronic renal failure, hemodyalisis, and idiopathic iron loss.…
Teaching point: For patients with chronic ocular conditions, patient re-education is key. ____’s condition is consistent with wet macular degeneration. Age Related Macular Degeneration (AMD) is the primary cause of legal blindness in North Americans 65 years of age or older. AMD is divided into two types: dry (also known as “nonexudative” or “non-neovascular”) and wet (also called “exudative” or “neovascular”).…
The right eye shows a 3-4+ cortical cataract. The left eye shows 1-2+ nuclear sclerosis. Posterior segment in the right eye demonstrates no view through the dense cataract. The left eye has a cup-to-disc ratio of 0.4.…
Duchenne Muscular Dystrophy Do you know what duchenne muscular dystrophy is? It obviously has something to do with your muscles it causes you to have muscle weakness which can lead you to have loss of mobility. This disease is most effective for males. Duchenne muscular dystrophy is a mutation, flaw or gene.…
There are 285 million people that are visually impaired in the world (WHO). Of those people, 248 million have low vision and thirty-nine million are blind (WHO). The causes of blindness fall into two categories: natural causes and environmental causes. Some natural causes of blindness are cataracts, (Landau 20), glaucoma (16), and macular degeneration (22). Environmental causes of blindness can occur from exposure to chemicals (30) and sharp objects puncturing the eye (29).…
The Usher syndrome type 1 G protein is encoded by USH1 gene. The USH1G gene’s cytogenetic location is on the q arm (long arm) in chromosome 17 at position 25.1 (17q25.1). Its molecular location on the chromosome 17 is at base pairs 74,916,082 to 74,923,262 (Summary: Usher Syndrome, Type 1G). USH1G gene’s main function is to provide information for making a protein, SANS, which is located in the inner ear and the retina. The protein SANS, interacts with other proteins which forms a larger protein complex which is critical for the development and function of the inner ear and retina.…
People rarely lose all of their vision from age-related macular degeneration. They may have poor central vision, but they are still able to perform many normal daily activities. Macular degeneration does not seem to affect a person’s life expectancy, but it does seem to affect a person's lifestyle. If a person develops AMD, they should expect a change in diet and everyday activities. To reduce the risk of further vision loss from AMD, a diet rich in green, leafy vegetables, fresh fruit, and fish is recommended.…
Fluid can start to accumulate behind the macula, the part of the retina responsible for focus. As the fluid accumulates, it can hinder the ability of the eye to focus. Proliferative retinopathy happens when damaged capillaries completely collapse, stopping blood flow. Lack of blood flow triggers the body to start growing new blood vessels to feed the retina. These vessels are very weak and tend to leak blood.…
Diabetic retinopathy is an major cause of blindness, and occurs as a result of long-term accumulated damage to the small blood vessels in the retina (American). One percent of global blindness can be attributed to DM and it is also one of the leading causes of kidney failure (Diabetes). The overall risk of dying among people with DM is at least double the risk of people without it…
Glaucoma is a common eye condition in which the fluid pressure inside the eye rises to a level higher than healthy eye. If untreated, it may damage the optic nerve, causing the loss of vision or even blindness. The body system directly affected is the nervous system. Glaucoma directly attacks the eyes, which are responsible for viewing the world and then transmitting this information to the brain. This affects the body to make an expected response.…
About the Product: Diabetes is a disease that millions of people from all around the world| suffer from every day, and if it isn't properly controlled, thing can go bad, really bad. Some of the very bad things that can happen, because of letting diabetes get out of control, are blindness, kidney failure and even blindness. Most people don't know this until the actually get thedisease and don't treat it the right way on a daily basis. More people today suffer from diabetes than ever before.…
Dustin Smalley Biology 257 May 4, 2016 Multiple Sclerosis What is Multiple Sclerosis? Multiple Sclerosis (MS) is a disease in which the immune system eats away at the protective myelin coating on the nerves causing communication issues within the brain and body. It’s not contagious, but it effects approximately 2.3 million people around the world, usually between the ages of 20 and 50 years. There are different types of MS and a very broad range and severity of symptoms.…
Alzheimer’s is a brain disease that slowly and progressively destroys memory cells in the brain and other types of brain cells. Today Alzheimer’s threatens the health system and about five million Americans. Death in Alzheimer’s has climbed up to fifty five percent. They say statin drugs are supposed to reduce the risk of stroke and cholesterol, but they actually increase the risk of dementia. The way that people live now is causing research to say that we will continue to die from Alzheimer’s.…
