Where have cases of Strabismus in children recently been found?
In a recent study it has been found out that a number of children are suffering from Strabismus or have some other kind of major refractive errors. The research was done on 815 six-year-old children who were randomly selected from the general masses in Shahrood, Iran. The research did not include children who were already suffering from congenital blindness. One of the researchers has noted that more emphasis must be given on the section of society that is experiencing relatively “high rate of hyperopia and astigmatism.” The startling results that have come out of the study indicate the need for proper diagnostic centers where therapy and treatment can be done to cure these errors. The research has got results where it has calculated that the prevalence of diminished visual acuity was 3.6%. The other errors that were studied are stereopsis, ocular alignment, Amblyopia, cover testing and cycloplegic refraction. Strabismus is a condition of the eyes where the eyes are not aligned properl
Strabismus may also be classified based on time of onset, either congenital, acquired or secondary to another pathological process, such as cataract.[2] Many infants are born with their eyes slightly misaligned. The best time for physicians to assess this is between ages 3 and 6 months. During eye examinations, ophthalmologists, orthoptists, and optometrists typically use a cover test to aid in the diagnosis of strabismus. If the eye being tested is the strabismic eye, then it will fixate on the object after the “straight” eye is covered, as long as the vision in this eye is good enough. If the “straight” eye is being tested, there will be no change in fixation, as it is already fixated. Depending on the direction that the strabismic eye deviates, the direction of deviation may be assessed. Exotropic is outwards (away from the midline) and esotropic is inwards (towards the nose). A simple screening test for strabismus is the Hirschberg test. A flashlight is shone in the patient’s eye.

More simply described, in such cases there is lack of coordination between the extra ocular muscles. This situation prevents the gaze of each eye to the same direction and hence it prevents binocular vision. In another explanation some experts think that Strabismus is caused due to a disorder in the coordination between the brain and the eyes. In some cases the situation becomes very severe because the individuals suffering from the error are unable to have proper depth perception. Sources:
