Retinitis pigmentosa is a genetic disorder that causes blindness in the people that are affected by it. I chose retinitis pigmentosa because my grandmother has this genetic disorder. The disorder is very costly on those who have it. The disorder has robbed my grandmother of the life she wanted. She is no longer able to do the things she once was. She is legally blind, cannot drive, and has trouble getting around crowded areas. Retinitis pigmentosa was discovered by Doctor Donders in 1857. Retinitis
Irradiation in the red/near-infrared spectrum (R/NIR, 630 – 1000 nm) has been recently used as a potential therapeutic strategy to treat different diseases and injuries such as Mitochondrial Disease, Degenerative Eye Diseases, Neurodegenerative Diseases, Cardiovascular Disease and Stroke, Metabolic Diseases (Eells et al., 2003), wound healing, central nervous system injury, and for restless leg syndrome (Fitzgerald et al., 2013). Dr. Janis Eells presented a study that was accomplished by her and
vision loss can make living a challenge. Retinitis Pigmentosa (RP) is an inherited condition that gradually tunnels field of vision and also leads to retinal degeneration. RP affects about 1 in every 3500 Americans (Openshaw, Branham, and Heckenlively, 2008). Living with RP is possible and people with RP can still have successful lives. Mutations in at least 60 different genes can cause RP, in turn causing different forms of the disorder (“Retinitis pigmentosa”, 2015). The mutation can also be “influenced
they both carry the same genetic variation of US. There are also three different types of US and each type faces a different way to manage/treat these issues (Wallber, 2009b). Usher Syndrome is distinguished by sensorineural hearing loss, retinitis pigmentosa (RP) and sometimes vestibular dysfunction is included (Sadeghi, 2006). RP is a
Photoreceptor Damage: Causes and Possibilities Over 10,000,000 people around the world suffer from some sort of blindness or handicap due to photoreceptor damage. These effects can be caused by a number of afflictions, including retinitis pigmentosa, macular degeneration, and tumors. These illnesses vary in severity from being a mere hindrance to completely blinding the individual. Until recently, those affected were left without hope of a cure or even a treatment that would somewhat improve
When a child is diagnosed with deafness, many parents often wonder what the exact cause of the child’s deafness is. In recent studies (Arnos K. &., 2007) 50-60% of hearing loss (moderate to profound, congenital, or early-onset) have shown genetics to be a large factor. Non genetic factors (i.e. maternal infection, prematurity or postnatal infection) may cause 40-50% of the remaining hearing loss. About one-third of children with hereditary deafness have features that are part of a genetic syndrome
have a functional visual pathway from the retina to the brain along the optic nerve as well as some intact retinal cells. This need for intact optical nerves \ intact retinal cells limits the potential recipients for treatment to people with retinitis pigmentosa and age-related macular degeneration and other genetic eye conditions that effect around 1.5 million people worldwide.
A recent report conducted by WHO showed that there are 39 million people who are suffering from blindness around the world and another 246 million with poor vision (WHO 2013). As a matter of fact, there is a certain need for a device to restore sight for the blind. Second Sight Centre has succeeded in creating a prosthesis device: the bionic eye Argus II. This device is an auspicious artificial eye, which can bring the hope of sight to the blind. It is considered as an innovation based on the definition
I grew up in Pune, India – a complex urban city with over 8 million people from different walks of life. A growing metro attracts a very diverse population, and what this did for me is foster a love for diversity and a craving for human interaction which ties directly into my passion for medicine. Pune presented a very unique environment, a result of its wide socioeconomic compass- one can find world-class medical facilities and problems in access to care within a 2-mile radius. Having both parents
It is possible to develop with conditions such as retinitis pigmentosa, genetic or developmental abnormalities C. Adults who are visually impaired may struggle with fulfilling employment and day to day activities IV. How are children affected- A. Some babies have congenital blindness- means they are visually
family consists of her Mom, Dad and, brother Brady. Mr. and Mrs. Burke have always been very supportive of Molly. Growing up she had a few signs that showed that something was going on with her eyes. At 4 years old Molly was diagnosed with Retinitis Pigmentosa, a rare disease and makes you lose your vision. But even before she was completely blind there were signs there was something wrong with her eyes. When in school, Molly wanted all books to be held close to her face. When her classmates went
signs of positive results. As patients and families put their faith on trial, their medical healings were overcome with a little dose of hope. With the similar experiences of Ann Davis, Maurice Williams, and Guy Riggs; Kai Kermani overcame retinitis pigmentosa, an “incurable” blindness. Kai was from England who took time out of her life to pray patiently for her to see the light i... ... middle of paper ... ... Works Cited Begley, Sharon. “This Is No Way To Cure Cancer.” Newsweek 26
Introduction Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. But it also contains highly organized physical structures which are called intracellular organelles. These organelles are important for cellular function. For instance Mitochondria is the one of most important organelle of the cell. Without
movements, senses, or activities. I choose a sensory impairment, Diabetic Retinopathy which is one of the types of visual impairments that people may happen to get. You also have four other types of visual impairments, cataracts, glaucoma, retinitis pigmentosa, and retrolental fibroplasia that you can also get. Diabetic Retinopathy is a complication of diabetes that affect the eyes. Well how can you get it? Well it’s caused by damaged blood vessels in the tissue that the retina which is located
Description: Color blindness, also known as color vision deficiency, is defined as the inability to see color or see color differences. The name color blindness can be deceiving because there is no actual blindness, only inability to see certain colors or any color at all. Color vision deficiency is a more fitting name for this disorder because it better defines the disorder. Color vision deficiency occurs when there is a problem with the pigments found in certain nerve cells of the eye called cones
Incomplete and Complete Achromatopsia The human eye requires both rods and cones for normal vision. Over 100 million rods are located in the periphery of the human eye, and about 6 million cones compose the fovea. Rods, the more sensitive of the two to light, are not able to differentiate wavelengths, thus cannot detect color, and perceive shades of grey, black, and white. Cones, on the other hand, are of three types, containing particular pigments. They are categorized as red, blue, and green
The moment you are infected with a disease, you are label by the many imaginations of society. These imagination are not only creative and limitless in culture, but they ultimately create a division between normal and abnormal. In the novel illness as Metaphor, the American author Susan Sontag critiques how speaking disease metaphorically has many consequences by leading to the stigmatization of a disease beyond its scientific condition. Sontag teaches us that stigmatization of disease causes
Multiple sclerosis Definition: Multiple Sclerosis is a demyelinating disease cause a widespread degeneration of the central nervous system (CNS) which gradually results in severe neurological deficits. The disease is characterized by remissions and relapse, erratic onset and duration is flare up acutely. Each relapse may involve different area in white matter in central nervous system (CNS) . Etiology: There is may involve in genetic and environmental factor, which may cause immunologically
