Strabismus is the most common cause of amblyopia. To avoid double vision caused by poorly aligned eyes, the brain ignores the visual input from the misaligned eye, leading to amblyopia in that eye (the "lazy eye"). This type of amblyopia is called strabismic amblyopia.
It is important to note that a young child with amblyopia rarely expresses any symptoms or knows that what they are experiencing isn't normal.
Improvements are possible at any age, but early detection and treatment offer the best outcome. It is important that children are taken to an optometrist for a comprehensive visual assessment during the first year of life to help catch problems like amblyopia at an early stage.
Treatment of strabismic amblyopia can include vision therapy, eye patching, eye drops, strabismus surgery to straighten the eyes, or a combination of those options. Treatment may also include the use of prescription lenses. Many people try non-surgical options first before resorting to surgery.
