Astigmatism on Children
THE EFFECTS OF ASTIGMATISM
(NEARSIGHTEDNESS OR FARSIGHTEDNESS)
ON THE
LEARNING PROCESS OF A CHILD

Introduction
Vision is one of our richest senses. Making it “the window of the soul”, provides us with a wealth of information about our environment and the objects in it; the sizes, shapes, locations of the things, their textures, colors and distance. It is also the most studied of all the senses, giving us the reason why we give that much high importance on our sense of sight (Sekuler, et. al, 2008).
The eyes receive light reflected from objects in the world, and from this light we perceive everything in our environment. It enables us to avoid falling into holes and oncoming cars on the street. It allows us to contact and to avoid things we don’t want. According to ….. we rely too so heavily upon vision that it is usually considered the dominant human sense.
But unfortunately, many people are suffering from many kinds of eye disturbances which one of these is the astigmatism that may conjunct to near-sighted or farsighted. Even those very young kids and children who are going to school have this kind of problem (Kumari, 2012); which can really have an effect on their learning, particularly in their school performance. It can somehow be a hindrance and a disadvantage on their part, depending on its condition if it is severe or not.
According to Kumari (2012) astigmatism is a condition of irregular curvature of the cornea or the lens of the eye where the light cannot focus on the retina, which leads to blurred vision. Astigmatism is a fairly common problem of the eye. Many times it goes undetected, even by the person who has an irregularly curved cornea or lens. It is also one of a group of eye conditions known as refractive errors which can cause a disturbance in the way that light rays are focused within the eye. Astigmatism often occurs with near-sightedness and farsightedness, conditions that may result from refractive errors. Astigmatism is not a

    Some symptoms may append myopia, cataracts, and retinal detachment(Verma). People with Stickler's Syndrome, have uncompromising nearsightedness, which is very high myopia. In some of the types of Stickler's Syndrome, the transparent gel that fills the eye, has an aberrant appearnace, which anyone could see with the naked eye(“Stickler's Syndrome”). Other problems may include cloudynedd of the eye, which cataracts, and when the very thin layer of tissue toward the back of the eye retrains from its nourishing collection of blood vessels, which is retinal detachment(Verma).Another disorder of the eye is called Glaucoma. This is when there is pressure is enhanced within your eyeball. The more pressure it has, it will eventually pinch a nerve that transmits the signal of sight from the retina to the brain, which could eventually turn into blindness. An Additional feature of Stickler's Syndrome is hearing loss, which s both conductive and sensorineural(Wilson). This could actually cause deafness. When doctors want to determine if their patient has hearing loss, they do a test called an audiogram. This measures the ability to discover a multiple of pitches of volumes and sounds. Another one is skeletal abnormalities, in other words, excessive joint flexibilility. Joint flexibility is when one is able to extend their arms and legs to a point where it is out of the range of motion that is…

    In Activity 2.4.1, you explored the anatomy of the eye and began to think about the function of each structure you dissected. The cornea and lens of the eye bend or refract light rays as they enterthe eye so that focused images fall on the retina. If the eyeball is an abnormal shape, the light will not focus on the correct point in the eyeball and vision may become blurry. Corrective lens can be used to compensate for this change in shape and bring the world back into focus.…

    Amblyopia is also known as Lazy eye . Lazy eye is an early childhood condition where a child 's eyesight in one eye does not develop as it should. People with amblyopia were subjected to playing video games for a specific amount of time. Scientists found out that playing video games helped patients recover a substantial portion of their visual functions (Li et al. 2011). This discovery demonstrated that restoring normal eye function to certain degree is still possible even beyond the sensitive period of brain…

    Astigmatism is usually caused by an irregularly shaped cornea, which most often in the shape of a football instead of a sphere. This causes light to fail meeting at a single point on the retina, and instead creates multiple focus points that fall short of the retina, or in behind it. Uncorrected astigmatism can cause eyestrain and headaches, especially after reading, and blurred and distorted vision to a certain degree. There are three types of astigmatism: myopic astigmatism, hyperopic astigmatism, and mixed astigmatism. Myopic astigmatism causes one or both of the principal meridians (the two imaginary lines, one vertical and one horizontal, that intersect at the middle of the eye) to become near-sighted. Hyperopic astigmatism is the exact opposite; it causes one or both of the principal meridians to become far-sighted, and mixed astigmatism is the mixture of both myopic and hyperopic astigmatism. Treatment options include eyeglasses, contact lenses, and refractive surgery. Astigmatism usually occurs early in life, so it is suggested to have children checked by an optometrist…

    We have limited brainpower capacity to process all the information available to us through our senses (Edgar, 2007, p11) and for our brains to allocate appropriate resources, this information gets filtered by cognitive processes. One of these processes is attention. Attention acts like a filter between what is sensed and what is perceived and allocates sensory information processing resources as appropriate.…

    I attended Cameron Elementary School on September 4, 2013 from 0800-1030 and Westmoore Elementary School from 1200-1400. The target population for screening at both schools was 1st, 3rd, and 5th grade students. They ranged in age from 5-12. Growth and development varied within each grade. The obvious height and weight as well as maturity levels were observed. It was apparent as to which children had special needs and required assistance to move from station to station due to a disruption in their daily routine. For the younger children we had to give simple commands to step on the scale and how to stand under the stadiometer. Some stood face forward instead of their back against the ruler. The older children were eager to know their vital statistics to compare with their classmates. For some it seemed like a competition as to who was taller. At the second school we did the distant vision screening and had different charts depending on the age group. The younger children simply had to read T, V, O, H, etc for both eyes, one at a time, while the 5th grade students had a separate group of letters for each eye.…

    SUMMARY Objective: Previous studies have reported that visual impairment can affect the mental health of children and adolescents. The aim of this study is to investigate the depression and anxiety levels and the self-concept characteristics of adolescents with congenital complete visual impairment. Method: This is a cross-sectional study. 40 adolescents with congenital complete visual impairment studying in a specialized primary school for visual impairment, and 40 sighted adolescents were included in the study. Both groups were matched in terms of age, gender and socio-economic status. The mean age of the adolescents in both groups was 12.82±1.17. The Children’s Depression Inventory, Piers-Harris Children’s Self-Concept Scale, Spielberger Trait Anxiety Inventory for Children and sociodemographic form were used in the study. The mean scores of the scales obtained from both groups were compared using the Mann-Whitney U test. Results: The difference between the two groups was not statistically significant either in terms of depression scores or in terms of total scores; the happiness, physical appearance, popularity, behavior and adjustment subscales scores of the Piers-Harris Children’s Self-Concept Scale. The intellectual and school-status subscale scores of the adolescents with visual impairment were significantly higher than those of the controls. Anxiety levels of the adolescents with visual impairment were significantly higher when compared with sighted adolescents. Conclusion: These results indicate that the depression levels and self-concept characteristics of adolescents with visual impairment are similar to those of sighted adolescents, whereas the anxiety levels of the adolescents with visual impairment are…
