This plastic response of the brain interrupts the brain's normal development, resulting in the ...

Diplopia, or double vision, occurs commonly after strabismus surgery.

In adults with previously normal alignment, the onset of strabismus usually results in double vision. A child with accommodative esotropia affecting the right eye Any disease that causes vision loss may also cause strabismus, [ 34 ] but it can also result from any severe and/or traumatic injury to the affected eye.
Ocular myasthenia gravis (MG) is a disease of the neuromuscular junction resulting in hallmark variability in muscle weakness and fatigability. MG is an autoimmune disease where anomalous antibodies are produced against the naturally occurring acetylcholine receptors in voluntary muscles.
