Visual impairment

The article illustrates findings describing separate visual pathways within the cortex that play different roles in interpreting visual information. These visual pathways include the ventral and dorsal streams which elicit visual perception and visual control of action, respectively. An important model for these findings was patient D.F., an individual afflicted with visual form agnosia, resulting in difficulties perceiving visual objects. In determining the origin of this patient's condition,…

it is so visual using sign language stimulates parts of their brain that are inactive due to the breakdown of spoken language. It is that stimulation that makes sign language act like a bridge for children with autism. “If visual skills are essential to the deaf child, and visual skills and visual languages are essential to the child with autism, then the communication needs of the child who is deaf and has autism would appear to be best served visually” ( Sign language acts as a visual aid for…

influenced by traditional beliefs. In addition, appropriate information is poorly targeted to persons at risk of developing the disease hence, the health and economic burden of glaucoma is continuously increasing. The Nigerian National Blindness and Visual impairment Survey has shown that glaucoma is the most prevalent cause of blindness and has emphasized the need for increasing glaucoma awareness and patient education in reducing blindness from this disease (Abdu 2013). In addition, (Prior et…

Visual Agnosia The textbook defined visual Agnosia as an impairment in object recognition which can be caused by brain damage. Visual Agnosia is a brain disease that has no cure. In the video, Kevin talked about his issue of visual Agnosia. Kevin can identify colors, faces such as his children’s pictures but can’t be able to locate an object. Kevin plays guitar, he cannot read music but know how to construct music by listening to it and reconnect it with his guitar. Kevin’s visual Agnosia made…

society. These same factors likely influence those who are blind, deaf, amputated, or marginalized in some capacity. The first stage in order to make significant policy must begin with identification. Deafness is often seen as a medical problem, an impairment bound by some biological defect, according to doctors (Higgins and Lieberman 11). According to Michael Higgins and Amy Lieberman, “[d]eaf children were often not identified until two and a half or three years (10). This would present…

it came across that deaf people should be protected by the ADA program. The ADA program stands for Americans with Disabilities Act. This act can protect any individual who is trying to apply for a job and gets neglected because of their hearing impairment. What this act does is that as long as you have all the…

temporarily or permanently due to eye problems that can provide information in a patient’s health status as well as problems with self-care. Changes in the structural components of the eye caused by aging begin early especially with the lens of the eye. Visual functions are reduced due to age-related changes of the nervous system and in the eye support structures. Three layers form the wall of the eye: sclera, choroid, and retina. The sclera, a thick, white, outermost layer that includes the…

of who was her parent. The next case was a 4 yr. old female had normal face detection, but she had an impairment of structurally encoding of faces. The next child was a 5 yr. old boy called T.A., who had problems in recognizing familiar faces and some difficulty with unfamiliar face matching. Another child was 8 yr. old called L.G., had problem with recognizing familiar faces. He had an impairment when looking at images that were in black and white but no problems when viewing color images. He…

Although we, as a society, are not doing a bad job supporting the students, we definitely have ways to improve by studying individual cases of hearing loss students across the country. In Overcoming the Barriers to Including Students With Visual Impairments and Deaf-Blindness in Physical Education, author Lauren J. Lieberman and Cathy Houston Wilson suggests some of the barriers teachers today face about the lack of resources towards deaf-blindness students. It is difficult to provide support…

the composition of the eye and even more by his interconnection with brain. How the eye actually works, his structure and the function will help us in better understanding how visual light is converted into our perception. The challenge of the image transformation from first encounter of light till the final step in visual cortex is revealing the incredible ability of the eye. Unfortunately, the eye as any other organs is the subject of many physiological and anatomical conditions that can…
