The app offers dedicated eye exercises that the patient performs while wearing an eyepatch.Evidence for vision therapy is unclear as of 2011. Older age
Treatment of individuals age 9 through to adulthood is possible through applied perceptual learning. Tentative evidence shows that perceptual training may be beneficial in adults. Epidemiology
Amblyopia occurs in between 2 and 5% of the population in Western countries. In the UK, 90% of visual health appointments in the child concern amblyopia.Depending on the chosen criterion for diagnosis, between 1 and 4% of the children have amblyopia. Research
A 2009 study, widely reported in the popular press, has suggested that repetitive transcranial magnetic stimulation may temporarily improve contrast sensitivity and spatial resolution in the affected eye of adults with amblyopia. This approach is still under development, and the results await verification by other researchers. Comparable results may be achieved using different types of brain stimulation, such as anodal transcranial direct current stimulation and theta burst rTMS.A 2013 study concluded that converging evidence indicates decorrelated binocular experience plays a pivotal role in the genesis of amblyopia and the associated residual deficits. Another study of 2013 suggests that playing a version of the popular game Tetris that is modified such that each eye sees separate components of the game may also help to treat this condition in adults.
Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. It results in decreased vision in an eye that typically appears normal in other respects. Amblyopia is the most common cause of decreased vision in a single eye among children and younger adults.The cause of amblyopia can be any condition that interferes with focusing during early childhood. This can occur from poor alignment of the eyes (strabismic), an eye being irregularly shaped such that focusing is difficult, one eye being more nearsighted or farsighted than the other (refractive), or clouding of the lens of an eye (deprivational). After the underlying cause is addressed, vision is not restored right away, as the mechanism also involves the brain. Amblyopia can be difficult to detect, so vision testing is recommended for all children around the ages of four to five.Early detection improves treatment success. Glasses may be all the treatment needed for some children. If this is not sufficient, treatments which encourage or force the child to use the weaker eye are used. This is done by either using a patch or putting atropine in the stronger eye. Without treatment, amblyopia typically persists. Treatment in adulthood is usually much less effective.Amblyopia begins by the age of five. In adults, the disorder is estimated to affect 1–5% of the population. While treatment improves vision, it does not typically restore it to normal in the affected eye.
