Recommended: Causes of cataract

According to Mayoclinic.org the definition of cataract is a clouding of the normally clear lens of your eye (July 2013). I would like to discuss with you the pathophysiology of this disorder, the causes of this issue as well as some of the effects it can have on you, and some treatment options for those you suffer from this internal eye disorder. A cataract affects the lens of the eye. The lens is generally clear in color, and it is elastic in nature. The lens is surrounded by a capsule like case and sits behind the iris inside the eye (“Cataracts” Linton 2012). When the lens of the eye becomes cloudy, blurred, or there seems to be a more dim vision which replaces the normal transparency, this is called a cataract (“Cataracts” Linton 2012). …show more content…

Cataracts can be caused from a traumatic event or simply because of degeneration related to becoming older in age. The lens of the eye may become cloudy or hard to see through at a slow rate of time or very quickly (“Cataracts” Linton 2012). Some reasons for the disorder are a contributing factor to the speed in which a cataract forms. Also, each individual is unique in that they all react to illness, trauma, or even congenital disorders differently. Some signs and symptoms of cataracts are clouded, blurred vision, increased difficulty seeing or driving at night, new or worsening sensitivity to light and or glare, seeing orbs of light or what some individuals call “halos” around lights, having to obtain and fill multiple eyeglass or contact lens prescriptions, when the whites of a persons …show more content…

Definitely, if you develop a sudden change in your vision, sometimes double vision or blurred vision (Mayoclinic.org 2013). There are different locations of cataracts therefore they have names based on their location. According to “Cataracts” Linton 2012, a central cataract is located in the center of the lens (nuclear cataract) and in this case the patients may still be able to use their peripheral vision just as they always have, they just tend to start to lose vision directly in the center of their eye. The second type of cataract, according to “Cataracts: Linton 2012 is the peripheral cataract (cortical cataract) where an individual can see straight ahead but cannot see out of either of their peripheries. There are cataracts that affect the back of the lens (posterior subcapsular cataract) in which the cloudy spot on the lens forms directly over the small area where the path of light shines on the retina. This type of cataract interferes with reading vision, distracts us and hurts our eyes when we are in bright sun light, and happens to case the “halos” that some people say they are seeing (Mayoclinic.org 2013; “Cataracts” Linton

    580 Words  | 2 Pages

    Glaucoma is a disease of the eye and it is fluid pressure within the eye rises and if the eye is left untreated the patient might lose vision or maybe even blind. But this disease is generally affects both eyes but although one of their eyes may have more severe signs or symptoms then the other eye. When you have glaucoma there are small spaces in the front of the eye and they are called anterior chamber. There is clear liquid that flows in and out of the anterior chamber and the fluid nourishes and bathes nearby the tissues. And if the patient has glaucoma the fluid dose not drain like it should drain but the fluid drains out of the eye. And this may lead to fluid build up and pressure inside the rises of the eye. Unless the pressure is brought down and controlled and the optic nerves and some of the other parts of the eye might become damaged leading to ...

  • Age Related Macular Degeneration

    3312 Words  | 7 Pages

    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...

  • The Risk Factors of Glacucoma

    1371 Words  | 3 Pages

    After laser surgery and eye drops don’t do the job making a drainage flap in the eye and inserting a drainage valve is next. Trabeculectomy is the filtering microsurgery involving the creation of a drainage flap. This flap will then allow fluid to “percolate” and later drain into the vascular system. All procedures aim to reduce the pressure inside the eye. Surgery may help lower pressure when medication is not sufficient, however it cannot reverse vision loss.

  • Retinitis Pigmentosa Research Paper

    1165 Words  | 3 Pages

    Retinitis pigmentosa is caused by damage to the retina of the eye. The retina is the light sensitive layer of tissue at the back of the eye. The retina focuses images in the brain and then sends them via electrical signals up to the brain. The retina is a very important part of the eye to help a person see. What is affected in the retina from this disorder are the rods in the eye. The rods allow a person to see in the dark. Retinitis pigmentosa slowly causes the rods in the eye to deteriorate over time. Retinitis pigmentosa also can cause the cones in people’s eyes to deteriorate. If a person’s cones deteriorate first, then the person first develops blindness in the center of their eye and they lose some of their color vision. This form of retinitis pigmentosa is much rarer than the form that deteriorates the rods in the eyes.

    The high percentages of individuals who endure this impairment justifies and practically demands future research because the causes are not fully understood. The need for future research can be better emphasized if those with normal vision try to empathize with victims of macular degeneration. One can only imagine how frustrating it must be to receive sensatrions only in the periphery of the retina. Because the macula encompassed the cone rich fovea, which is used to focus on objects, the fovea degenerates as well. This occurence inables individuals to interpret the sensations they experience.

  • Myopia Argumentative Essay

    918 Words  | 2 Pages

    As humans age, they frequently develop a condition known as presbyopia. This condition decreases the person's ability to focus sharply on those object which are nearby and is the result of the lens of the eye hardening. In addition, astigmatism requires a person wear prescription eyeglasses and/or contact lenses. Astigmatism arises when the curvature of the eye is irregular. The eye is normally shaped liked a soccer ball or basketball. With astigmatism, it takes on a more oval shape and resembles a football. Due to the irregular curvature, the eye processes light differently and leads to blurred vision. The degree of blurriness is determined by the degree of

  • The Disease Retinoblastoma

    552 Words  | 2 Pages

    Many signs include a "white pupil," also known as leukocoria. Retinoblastoma can occur in either one or two eyes (Paul T. Finger, Pg. 1). This abnormal white pupillary reflex is sometimes referred to as a cat's eye reflex. Another sign of retinoblastoma is a crossed eye (Ambramson, Ch3). Leukocoria doesn't always end up as being retinoblastoma, it can even result in: congenital cataract, Toxocara canis, Coat's disease, and persistent hypertrophic primary vitreous (PHPV) (Finger, Pg.2). Retinoblastoma occurs when there's a mutation or deletion of the q14 band of chromosome 13 (Finger, Pg. 1). Symptoms can be painful if not treated quickly. Some include a red, painful eye, swelling of the surrounding eye, poor vision, dilated pupil, even extra fingers or toes, and retardation (Ambramson, Ch3).

  • Amblyopia

    1809 Words  | 4 Pages

    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).

  • Macular Degeneration

    1727 Words  | 4 Pages

    Macular degeneration in general can affect many people in minor or drastic ways. People who experience this form often complain of vision loss when they are in dim light, especially when they are reading. The "dry" type is often characterized by a more gradual loss of vision compared to the "wet" type. Signs of this disease include an increase in drusen, which is an accumulation of a yellow-white substance, in the underside of the macular retina. A loss of cells can be seen in the macula. The macula is our sensitive sight region, where intricate detail can be seen. Thus, vision in this area is helpful and necessary to drive, read, focus on small details, and recognize familiar faces. The macula is located in the back of the eye known as the retina. The macula is only about 5 mm in diameter, and includes the fovea, which gives us our detailed central vision. If a person suffers from the "dry" form in one eye they will be more likely to develop it in the other eye as well.

    The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness, everything appears in shades of gray.
