The Dilemma of Macular Degeneration
According to Baily and Hall, while visual impairment early in life is associated with inherited congenital disorders, abnormal fetal devepment, and problems associated with premature birth, most eye conditions are associated with aging. They claim that over 70% of the visually impaired population in the United States is over 65. Age related maculopathy, also called macular degeneration, or AMD, impairs the center of vision in older individuals. The macula is the region in the back of the retina that surrounds and includes the fovea (Goldstein 1999). It is important to understand that when this degeneration progresses enough, the condition constitutes blindness because the foveal area is what is

Danger can exist for victims of the condition when simply walking down the street or even through their own homes. While there is yet no cure for macular degeneration the research is in progress. Two main areas of research include investigating the causes and exploring potential treatments.
According to Friedman, progress in the effort to stop or prevent AMD will be slow until the cause is learned. He claims retinal pigmant epithelium damage to be the prominant theory explaining the choroidal circulation changes that lead to AMD. Although Friedmal himself does not subscribe to this theory, other researchers do and use it as a basis for study. Grunwald, Harisprasad, Dupont, M. G. Mguire, Fine, Bruker, A.M. Maguire, and Ho compared choroidal blood flow in subjects with AMD to a control group. They used laser doppler flowmetry to asess the volume, velocity, and flow of blood in the center of the fovea. Ten subjects with no drusen (cellular debris) were compared to 20 subjects with ten or more large drusen. The average visual acuities of the two groups was very close. No significant differences between age, blood pressure, or intraocular pressure was revealed between the subjects. Spraul, G. E. Lang, Grossnik laus, and G. K. Lang questioned the validity of the study. They claim doppler flowmetry to be an imperfect method for such a study because of multiple light scattering properties of the tissue. They also
Retinitis Pigmentosa (RP) is one of such currently untreatable causes of blindness. RP, along with Age Related Macular Degeneration (AMD) are amongst the more frequent causes of blindness in the developed world (Greenwald 2009), while RP itself is the leading cause of inherited blindness (Palanker 2004).
Macular Degeneration is a disease of the eye that gradually causes loss of a person’s central vision. Approximately 1.75 million Americans suffer from vision loss associated with the disease (All About Vision 1). The leading cause of blindness in people over the age of 60, Macular Degeneration, exists in two types (National Eye Institute 1). Both the wet and dry versions of the disease have similarities in risk factors, but differ in symptoms and treatments.
To understand how macular degeneration affects the eye, we must first know how the eye itself functions and why it is important to have the macula intact. A heathy eye is made of different layer that helps people to see colors, movement and to see images plainly. The macula is part of the retina, the retina is
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).

The research topic I will be introducing is Age-Related Macular Degeneration. This has been classified as a degenerative disorder that distresses the macula in one’s eye. AMD is unfortunately a common illness that individuals over 65 suffer from and that is a central cause vision loss. AMD doesn’t have a set disease pathway, in some individuals it advances slowly so that loss of vision does not arise for a long time. The disease can also advance much quicker and may lead to lack of vision in either or both eyes. The disease begins a blurry area near the center of one’s vision which grows larger and larger possibly causing a blank space in the eye (Boyd, 2013). Research is being done on AMD because it is a prevalent illness and has extreme consequences.
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.
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,
According to Qualter, “propaganda is thus defined as the deliberate attempt by some individual or group to form, control, or alter the attitudes of other groups by the use of the instruments of communication, with the intention that in any given situation the reaction of those so influenced will be that desired by the propagandist.” The existence of a clear purpose of propaganda is the key to understanding what propaganda is; Qualter’s definition is compelling because he specifically identified the reason why propagandists want to shape public opinions and he points out the means of how do propagandists form, control and alter public attitudes. Propagandists try to make the public think and feel in certain ways because the mood of the public
As humans, we don't always see with our eyes, but often with our imagination (Grunwald, 2016). Often times as people we never realize how useful our vision really is to us. You really don't think about something like that until it would actual happen to you. Throughout this essay, you will learn how the body is affected by Macular Degeneration (MD). Different signs and symptoms, as well as the etiology of MD, will be discussed. In the following, diagnosis tests and treatments may also be listed in order to help others who would like to know more about MD. Not to mention, you will learn the incidence and progression of MD. Furthermore, information though agencies and associations, as well as new research about MD will be given.
Really the cause of Macular Degeneration is unknown. Recently researchers have discovered that a group of genes called ABCR contribute to the disease. When someone has these genes the likeliness of this person to form Macular Degeneration increases by 30 percent. In most situations Macular Degeneration is
The other type of macular degeneration is “ wet”, it is known to be the most severe of the two, it occurs when there is “
What is ambition? Ambition is described as eager for success, power or fame. For Macbeth. Ambition was what drove him to become great, it forced him to change his nature towards evil. At the beginning of the play, Macbeth was portrayed as a courageous soldier who fought for his King without mercy. But once the witches planted the seeds of greater things and Lady Macbeth fuelled his ambition, which lead him to become greedy and power hungry.
Right now, although there is no way to prevent glaucoma, there are many successful treatments available to prevent the blindness caused by glaucoma. Because the gradual vision loss of chronic glaucoma may not be noticed until it is too late, regular eye examinations, dilated exams of the optic nerve, and screening tests of the visual field are essential for all persons aged 40 and older, especially is your family has a history of glaucoma.
Matoa Indonesia is the first wooden watches brand in Indonesia. This brand’s name inspired by the name of the origin fruit from Papua and Sulawesi Island. This unique name chooses to promote Indonesia in global. This happened as people will be curious to the Matoa’s name. Then they will googling it and the Indonesia will come first as a result. So besides the profit, Matoa also consider sharing the Indonesia pride and culture through its name.
Vision challenge or impairment is when a person’s degree of seeing is very low and the affected person requires assistance in order to carry out daily routine. Significantly, for one to qualify as visually impaired there must be prove that a person cannot undertake duties by himself without necessary assistance. For a person to qualify as a visually challenged, there must be a prove that the affected eyes cannot be conventionally treated. Visual challenge cannot be corrected by surgery, refractive measures neither by medication and that is why it is termed as visual impairment. The most rampart causes of visual challenge are trauma, degenerative or congenital means and a variety of diseases. In the society,
