Amblyopia (lazy eye)
Amblyopia, also called "lazy eye," is an eye condition which develops in early childhood. For a number of reasons, the images from one eye (or in rare cases, both eyes) will be "ignored" by the brain. If this is left untreated, especially during the early vision development period in one's life (until around age nine), these neurological pathways will become permanent, resulting in a lifetime of reduced vision. Having one amblyopic eye also puts added strain on the dominant eye, in which case future eye disorders are more likely.
Amblyopia symptoms may include:
Amblyopia is often difficult to diagnose in children, since they often don't know they have a vision problem. A doctor usually tests for the condition by blocking each eye and observing the patient's response to visual tests. Amblyopic patients will often tend to do poorly on three-dimensional image tests.
Several conditions lead to Amblyopia:
Whatever the origin, treating amblyopia requires a therapy aimed at making the child use the weak eye. Most commonly used is an eye patch over the dominant eye worn full time or intermittently, over a period of a week or two, or longer, until the weaker eye matches the stronger one. Alternately, the ophthalmologist may prescribe a blurred lens, or Atropine eye drops, which prevent the dominant eye from focusing. These serve the similar purpose of imposing use of the weak eye.
Proper treatment during early childhood will often lessen or reverse amblyopia; however, it is common for the disorder to recur during this period requiring treatment to resume. Once a child passes the age of nine, amblyopia will usually not relapse if it has been successfully treated up to that point. Conversely, it is much more difficult to treat older patients with amblyopia. Nonetheless, treatment can still be worthwhile for those beyond early childhood.
