Squints and Lazy Eyes
Amblyopia is a condition in which vision in one or both eyes cannot be fully corrected even after the correct eyeglasses have been prescribed. In a child with normal visual development, the brain receives information from both the right eye and the left eye and combines the two to see one clear picture of the world. This “combining” of information from both eyes is called “fusing or fusion.” Amblyopia occurs when the brain is unable to “fuse” or combine the information from both the right eye and the left eye. When the brain is unable to fuse this information, it learns to ignore or “suppress” information from one eye. This leads to a lack of development or deterioration of vision in the eye not being used.
The medical name for squint is strabismus. It is a condition where the eyes do not look in the same direction. Whilst one eye looks forwards to focus on an object, the other eye turns either inwards, outwards, upwards or downwards. Most squints occur in young children. A child with a squint may stop using the affected eye to see with. This can lead to visual loss called amblyopia, which can become permanent unless treated early in childhood.
Most squints and lazy eyes in children are treated on the NHS and Hospitals. Treatment mainly consists of prescription glasses, patching for lazy eyes and surgery for squints if it is bad enough. However treatment usually stops at the age of seven years old. Treatment for adults is usually restricted to surgery.
It is however possible to offer some improvement to squints and lazy eyes at almost any age with Vision Training and we have many examples of patients who have benefitted. Each case is different and improvements are hard to predict but age is no limitation.
