Achromatopsia Research Paper

Colorblindness is a defect in the perception of colors, caused by a deficiency in specialized cells in the retina that are sensitive to different colors. The term is often used today during political discourse, often by members of some factions of liberalism, when claiming that one’s race should be irrelevant to any decision making process. It is a form of moral posturing; that one should see an individual as simply an individual, but not as part of any larger group or culture. As if this philosophy will enable us to bridge any gaps between races, this thought attempts to focus on how we are all the same, rather than how we differ. Teachers and administrators are required to complete coursework pertaining to multicultural education

Here are some interesting facts on Achondroplasia. Achondroplasia is a small limbed dwarfism. A disorder of bone growth which stops the changing of cartilage to bone. Here are some major causes of mutations in the FGFR3 gene. The symptoms of Achondroplasia are health problems such as breathing stops or slows sown at small amounts of time, obesity, ear infections, in childhood individuals get a permanent sway of lower back, and pain and weakness in legs. Those are some interesting facts on Achondroplasia.

A medical definition of vision impairment is a sine qua non that prohibits 20/20 vision in one or both eyes (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; Vision Australia, 2015; Webster & Roe, 1998). Examples of vision impairment include, cataracts, which has the lens inside the eye increasingly cloudy; albinism, which is passed down genetically affecting clear vision and causes sensitivity to bright light; optic nerve damage, which affects field of vision as those nerves controlling vision are disrupted; macular degeneration, where parts of the retina that control colour and fine details are affected; retinitis pigmentosa, which is an ongoing reduction of the field of vision available and nystagmus, where the eye flickers involuntary (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; American Foundation for the Blind, 2015; Vision Australia, 2015 ; Baton Rouge Regional Eye Bank, 2015).

Since AAV2 vectors do not eliminate or repair the faulty gene, the therapeutic effects may not be permanent. In several studies, improvement of visual sensitive peaked a few

Visual impairment is a state wherein an individual experiences difficulty in seeing or not being able to see anything physical presented to them. According to Mandal, MD (2013) It is a state where a visually impaired person’s eyesight cannot be corrected back to a “normal level”. Visual impairment is often associated with old age. In Europe, an estimated 15.5 million people have visual impairment and in seven countries in Europe, about 50% of blindness is caused by age-related macular degeneration. (Dibb,

not being able to see colors, and when examined more closely, you can see that quite a few

Three things that I find interesting were nature verses nurture controversy because we as a human being always look at one side and make a huge deal of the stuff for example, negative behavior often credit to neighborhoods and environment. We do not see the nature affects the nurture and nurture affects the nature. Another one was genetic links because we do inherit certain gene from our parent for example, my mom is allergic to beef meat so as I and therefore, I’m unable to digest too. Next is outdoor play because playing has nothing to with vision especially when people believe watching TV constantly can dim our vision because many children in developing countries do not have access to television or internet and still got problems with

The family reports not having any neurological problems, and no one in their family have had any history of this as well. The mom wears glasses and is near sighted, and the children have great vision, no problems to report as of now. The dad has great eye sight as well, no problems to report. Everyone can see, hear, touch, and smell quite well, no issues to report. The family have yearly eye check up, to make sure that everything is going well for the eye sight

The topic that we decided to present for our Community Engagement project was color blindness. We presented our project to an Ecology Lab class of 11 participants. The PowerPoint over color blindness covered what color blindness is, the view through the eyes of a color blind human, the genetics behind color blindness, the diagnosis and treatment of color blindness, and the acknowledgements. Our presentation started at about 3:45 and lasted for about 10 minutes. The participants were pleasant and attentive while we presented.

“Arthrogryposis is a condition that causes joints to be stiff and crooked at birth. The individual’s intelligence is relatively normal. The patient will have stiff upper and lower joints, with fixed internal rotation of the shoulders, extension of the elbows, flexion and ulnar deviation of the wrist. The lower extremities will exhibit external rotation of the hips and knee flexion contracture” (Reed, 2011).

Oculocutaneous albinism or OCA is a set of four (or seven, including subdivisions) rare genetic disorders that are caused by mutations in up to seven different genes and are characterized by a complete lack or reduction of the pigment melanin in the eyes, hair, and skin. An estimated 1 in 20,000 people worldwide are born with this disorder. The conditions of OCA are caused by mutations in genes that are responsible and necessary for producing the melanin pigment in specialized cells (melanocytes). Not having enough of the melanin pigment can result in abnormal eye development, resulting in vision problems, and light skin that is easily damaged by the sun, at times resulting in different skin cancers, including an aggressive form called melanoma. Symptoms of this condition can also include nystagmus (involuntary back and forth movement of eyes), iris transillumination (reduced pigment in iris), reduced pigment in the retina, macular hypoplasia (poor development of the macula, resulting in abnormal foveal development in the retina), generally poor visual sharpness, photophobia (increased sensitivity to light), and strabismus (abnormal connection of the nerves from retina to brain, keeping the eyes from tracking

Based upon observation of the F1 generation, we hypothesize that the inheritance of the white-eye (W) mutation is sex-linked and recessive wild type.

I have decided to do my first discussion topic over the unique disease Vitiligo. I say unique, simply because of the effects this disease has on pigmentation of one’s skin. Vitiligo is relatively common worldwide however; some countries have more reported cases of this specific disease.

“Pay close attention to each student’s individual needs; provide a curriculum similar to that for sighted students; and expect students to integrate into their communities.” (Hall, 2012). There are many different categories of visual impairments that individuals can fall under. People can have low vision, visual acuity, or total blindness along with others. Visual impairment comes in two ways. Friend (2018) claims “Congenital visual impairment refers to a condition that is present at or near the time of birth. An adventitious visual impairment is a condition that is acquired at birth, either in childhood or at some later point in life.” (P. 359). According to Friend (2018), “Visual impairments result when problems exist in the structure or functioning of the eye, when the eye is damaged through illness of injury, or when a neurological problem prevents communication between the brain and the eye.” (P. 360). Friend (2018) found “Retrolental fibroplasia (RFL) is the condition where too much oxygen is placed in the premature incubator where babies are given uncontrolled amounts of oxygen to assist their breathing.” (P. 357). Stevie Wonder became blind through this particular situation. Visual impairment has been around for centuries, but just as the world advances so does the knowledge of visual impairment.
