Amblyopia - Wikipedia, the free encyclopedia. Amblyopia, also called lazy eye, is a disorder of sight due to the eye and brain not working well together. It results in decreased vision in an eye that otherwise typically appears normal. It is the most common cause of decreased vision in a single eye among children and younger adults. This is done by either using a patch or putting atropine in the stronger eye. Without treatment amblyopia typically persists into adulthood. Evidence regarding treatments for adults is poor. People typically have poor stereo vision, however, since it requires both eyes. Those with amblyopia further may have, on the affected eye, poor pattern recognition, poor visual acuity, and low sensitivity to contrast and motion. Take a look at our extensive selection of military and law enforcement equipment here at Special Forces Gear. Back; Special Response Team. In addition, individuals with amblyopia suffer from binocular abnormalities such as impaired stereoacuity (stereoscopic acuity) and abnormal binocular summation. However, sub- clinical deficits of the . Children's brains, however, are more neuroplastic, and therefore can more easily adapt by suppressing images from one of the eyes, eliminating the double vision. This plastic response of the brain, however, interrupts the brain's normal development, resulting in the amblyopia. Recent evidence points to a cause of infantile strabismus lying with the input to the visual cortex. In particular, they tend to make more saccades per line than persons with normal stereo vision, and to have a reduced reading speed, especially when reading a text with small font size.

According to a survey by the American Academy of Ophthalmology, nearly two out of three American adults report having eye or vision problems. Ocular dominance, sometimes called eye preference or eyedness. The eye patch simply presents the dominant eye with a static unchanging visual field containing. Eye exams for children are. Penalization usually consists of applying atropine drops to temporarily dilate the pupil, which leads to blurring of vision in the good eye. This helps to prevent the bullying and teasing associated with wearing a patch, although sometimes application of the eye drops is more challenging. The ocular alignment itself may be treated with surgical or non- surgical methods, depending on the type and severity of the strabismus. The eye which provides the brain with a clearer image typically becomes the dominant eye. The image in the other eye is blurred, which results in abnormal development of one half of the visual system. Refractive amblyopia is usually less severe than strabismic amblyopia and is commonly missed by primary care physicians because of its less dramatic appearance and lack of obvious physical manifestation, such as with strabismus. Also pediatric refractive surgery is a treatment option, in particular if conventional approaches have failed due to aniseikonia or lack of compliance or both. In some cases, the vision between the eyes can differ to the point where one eye has twice average vision while the other eye is completely blind. Deprivation and occlusion amblyopia. If not treated in a timely fashion, amblyopia may persist even after the cause of the opacity is removed. Sometimes, drooping of the eyelid (ptosis) or some other problem causes the upper eyelid to physically occlude a child's vision, which may cause amblyopia quickly. Occlusion amblyopia may be a complication of a hemangioma that blocks some or all of the eye. Other possible causes of deprivation and occlusion amblyopia include obstruction in the vitreous and aphakia. This has been confirmed by direct brain examination. Hubel and Torsten Wiesel won the Nobel Prize in Physiology or Medicine in 1. One should also be wary of over- patching or over- penalizing the good eye when treating amblyopia, as this can create so- called . Treatment is continued as long as vision improves. It is not worthwhile continuing to patch for more than 6 months if there is no improvement. There is also a greater chance of achieving 2. The app offers dedicated eye exercises which the patient performs while wearing an eyepatch. Children from 9 to 1. Adolescents aged 1. It is uncertain whether such improvements are only temporary, however, particularly if treatment is discontinued. This approach is still under development. It has also been suggested that comparable results can be achieved using different types of brain stimulation. National Eye Institute. Retrieved 2. 7 July 2.
