A:
A convergent squint or strabismus
is a failure of the two eyes to look at the same object thereby
preventing binocular vision. Human binocular vision develops during
the first few years of life. Interruption to the motor, sensory,
or CNS components, for example nerve or muscle defect, can lead
to sensory or central defect. Causes of many squints are not fully
understood although the majority seemed due to hereditary factors.
The degree of the stabismus must be determined by a specialist on
arrival.
