In strabismus or squint, one or both eyes deviate inwards or outwards . Squint, known medically as strabismus, occurs when instead of moving in tandem, each of the eyes points in a different direction. One eye deviates (either constantly or intermittently) from the normal visual axis, which results in the inability of the brain to fuse together the images from the right and left eye. In this physiological condition, the size of the eyeball is smaller than average and the light is focused in behind the retina. Hyperopia, also called far-sightedness or farsightedness, is an eye condition in which somebody is unable to bring close objects into proper focus. xxiv, 688.

Of the 65 infants 31 (48%) developed strabismus (Group 2B). Pain perception in children is complex, and is often difficult to assess. Because no verbal response from the child is necessary, these types of pediatric vision screenings or vision tests can be performed even when the child is very young or preverbal.
