Glaucoma in the United States Over the Last Ten Years
This research paper examines glaucoma over the age of 40 in the United States, in the last 10 years. Knowing the fact that glaucoma is the second leading cause of blindness in the United States leads us to choose this subject for research. Glaucoma is a group of eye diseases that gradually steals sight without warning and often without symptoms. Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires and is responsible for carrying the images we see to the brain. The two main types of glaucoma are open angle glaucoma, or primary open angle glaucoma (POAG), and angle closure glaucoma. Currently, there is no cure for glaucoma. Glaucoma is a chronic disease that must be treated for life. However, much is happening in research that makes us hopeful a cure may be realized in our lifetime. There is exciting work being conducted by scientists all over the world in the areas of genetics, neuroprotection and neuroregeneration. These areas of study deal with the origins and pathology of glaucoma as opposed to managing symptoms. A cure is on the way.
Glaucoma over the Age of Forty in the United States
The term "glaucoma" encompasses a group of eye diseases, not a single entity. Glaucoma is described broadly in terms of aqueous fluid drainage through the trabecular meshwork, the major outflow pathway. There are two main types: angle closure glaucoma and open angle glaucoma. Open angle glaucoma is far more common in the United States.
The American Academy of Ophthalmology defines primary angle closure glaucoma as "An appositional or synechial closure of the anterior chamber angle caused by relative pupillary block in the absence of other causes of angle closure". The American Academy of Ophthalmology defines primary open angle glaucoma as a "Multifactorial optic neuropathy in which there is a characteristic acquired loss of optic nerve fibers". Classifying glaucoma broadly into angle closure glaucoma or open angle glaucoma is helpful from both a diagnostic and pathophysiological perspective.
Problem Statement
In the United States, approximately 2.2 million people age 40 and older have glaucoma, and of these, as many as 120,000 are blind due to the disease. The number of Americans with glaucoma is estimated to increase to 3.3 million by the year 2020. Each year, there are more than 300,000 new cases of glaucoma and approximately 5,400 people suffer complete blindness.
They say that the eyes are the windows into the soul. When damage to the eyes occur it is usually irreversible, meaning that if this does occur, it is definitely best to find a respected ophthalmologist to fix the problem. Meet Karen D. Todd, my aunt and opthamologist at the Florida Eye Institute in Vero Beach, Florida. Dr. Todd practices general ophthalmology with an emphasis on the latest treatments and diagnostic testing for glaucoma.
Optometrists have accepted vision therapy, which is a medical treatment for optical muscle disabilities, as a feasible treatment used for eye related problems; claiming the treatment can strengthen vision and give the patient the opportunity to understand visuals quicker and clearer (Press). Vision therapy originated in the 1950s and over the past 25 years, has gained popularity, mainly because of new technological innovations in the field of treatment. Generally, vision therapy is prescribed as a measure mainly for people between the ages of 3 and 18. With the results from a comprehensive series of eye tests, the optometrist can work with the patient using special instruments—prisms, filters, occluders, and eye lenses—and strengthen the eye muscles, thus improving sight. According to optometrists in favor of vision therapy, these methods of treatment using these instruments function as safer routes to repair eye disabilities. Although vision therapy can yield favorable results, the practice as a treatment for innate eye disabilities has been in hot debate lately; as it can exceed $8000 and insurance companies do not cover the treatment. For decades, insurance companies have refused to accept vision therapy as a legitimate method for repairing eyesight (Boink). Concomitant with lack of insurance, the cost for a full treatment can exceed $8000, and doctors cannot guarantee a successful outcome. Recently, parents of children with eye related disabilities, such as amblyopia (lazy eye) and strabismus (cross-eye), and doctors have attempted to cooperate with public schools to allow families access to school-funded doctors to practice vision therapy. With a tight budget, most schools cannot afford to supply vision therapy, and a...
Vision loss from glaucoma is permanent but can be prevented with early detection and treatment. Since the symptoms of the disease are usually unnoticeable, regular eye examination are important especially for persons over the age of 35 and those in high risk group.
Age related macular degeneration (AMD) is the leading cause of blindness in people over the age of 50. Every ten years after the age of 50 the prevalence of this disease increases exponentially. Many different factors contribute to the development of AMD including genetic, environment, and metabolic functions. Aside from smoking, abnormal blood pressure, and an unhealthy diet low in fruits and vegetables, many more studies are concluding that similar inflammatory and oxidative processes seen in other age related diseases are also playing a key role in the development of AMD. This disease affects the central areas of the retina and choroid. In return central vision is impaired while peripheral vision is usually not lost. AMD is seen in two different forms, the earlier nonneovascular (dry) type and the more advanced neovascular (wet) type. Each form has its own specific pathology and unique characteristics that set them apart. Fatty, protein deposits called drusens may be the key risk factor in understanding dry AMD pathology, progression, and treatment. Once the more advanced wet AMD is diagnosed, pathology and treatment are targeted around the formation and destruction of abnormal blood vessels, characteristic of the wet AMD eye. The increasing prevalence of AMD has influenced more investigation into what factors can be modulated to prevent the onset or to stop the progression of AMD. Early diagnosis is very important because this is when an eye doctor can spot the early signs of the disease through ultrasound or angiography. This text will discuss the pathology of drusens and the role of inflammation and oxidation in the aged eye. By better understanding these processes more effective treatment approaches and preventive...
In conclusion Michael Jackson will be remembered has one the 20th century’s and music greatest artists. His iconic sound, style, and dancing will always be remembered by upcoming generations. He transformed the music video into an art form by including special effects, famous cameo appearances, dance routines, and complex story lines. Though his personal life was often publizied for the world to see Michael Jackson will always the “King of Pop” in our hearts and minds.
Imagine a researcher requesting you to copy a picture. It's a simple task. You move your instrument of illustration across a sheet of blank paper with ease, glancing from the given picture to your own sketch in progress. When you are finished you observe a satisfactory replica and feel a sense of accomplishment and proficiency with the similarity you have achieved between picture and sketch. Then the researcher queries whether you can tell him what you have drawn. You search the interconnected lines, the edges, and the shapes of your sketch but cannot answer what the picture represents. Finally, an explanation is given. You have just drawn a house- a simple triangle resting on top of a square. Your sense of accomplishment is quickly replaced with a feeling of despair.
Introduction: Perhaps no one has received this title in history “the king of pop”, now a days many artist’s have arisen and have performed but not as the king of pop known worldwide and in history, has dominated the world of pop as Michael Jackson.
Another problem people have with the pancreas is pancreatic cancer. Each year about 29,000 Americans and 3,000 Canadians are diagnosed with it.
Amblyopia is a condition in which visual acuity in one eye is greatly reduced. It is caused by lack of stimulation or disuse during visual development (Rose, 1998). Because the eye is not fully developed at birth (Jarvis, 1992, as cited in Rose, 1998), infants need stimulation to complete the visual neural pathway. When one or both eyes are inhibited, for example due to misalignment of one eye (strabismus) or a large difference in refractive power between two eyes (anisometropia), the neural pathway for the inhibited eye develops abnormally, or does not develop at all. At approximately six years of age eye development is complete (Stager, 1990, as cited in Rose, 1998). Before visual development is complete amblyopia can be treated. If it is caught and treated at an early age, normal vision can be preserved (Rose, 1998).
Open-angle glaucoma - With this form of glaucoma, the loss of vision occurs so gradually it is rarely noticed. However, as eye damage increases, you will eventually find that you have lost a lot of areas of your peripheral vision, especially the field of vision near your nose. As larger areas of your peripheral vision fade, you may develop tunnel vision -- vision that has narrowed so you see only what is directly in front of you. If glaucoma is not treated, even this narrowed vision disappears into blindness. Once gone, areas of lost vision canno...
First taking to the stage at the age of just 11 as part of his family's gig The Jackson 5, Michael Jackson grew quickly into the superstardom, which would both reward and plague his life. An apparently unstoppable creative and financial force through the highs of his career, 'The King of Pop' struggled with a confused and turbulent private life that was often made appalling public. In the wake of his shock death though, it is for his artistry - and not his controversies - that he will be remembered and sadly missed.
Robert, a 65 year-old male, has trouble reading fine detail, especially out of his central vision. He complains that his vision is blurred and that it is harder to see while operating a motor vehicle. In addition, sometimes objects appear wavy or crooked, which impairs his vision. His worst symptoms were that he occasionally lost the ability to distinguish between the features of familiar faces and he had a localized blind spot. Robert is not alone; many people suffer from symptoms related to loss and distortion of the visual field. He suffers from macular degeneration, the leading cause of decreased vision loss in the United States, especially for people over the age of 50 (Philippi, 2000).
Reflection is the process of analysing an activity with a view of changing an existing approach or adopting a new perspective on an experience (Nguyen et al 2014). Boyd and Fales (1983) state “that this process is central to understanding the experiential learning process”. According to Trottier (2015) Open Source Intelligence (OSINT) is the procedure of an organisation gathering and examining information that is available to anyone. Web sites and applications dedicated to Social media is one of the most popular in OSINT for information generation and widespread dissemination; security and intelligence agencies can capitalise on these opportunities to covertly study, things such as terrorist group behaviour, cultural contexts and recruiting
...he cornea is deformed so that its surface is oval instead of spherical. Light rays are distorted at the entrance of the eye. This produces a blurred image and is known as astigmatism. To correct it, glasses are given a nonspherical or cylindrical curvature. Cross-eyes and walleyes are produced when both eyes do not work together because of weakness of the eye muscles.
