Strabismus, a misalignment of the eyes also referred to as 'squint,' is one of the most common ocular disorders in humans, affecting 1 to 4% of the population. It is frequently associated with amblyopia (uniocular visual neglect) (Parikh et al., 2003).
Strabismus is also a feature of several syndromes, including congenital fibrosis of extraocular muscles (see, e.g., CFEOM1; 135700), Duane retraction syndrome (126800), and chronic progressive external ophthalmoplegia with myopathy (530000). [from
