Explain in detail about the Concomitant squint

Concomitant squint is also called comitant squint. It means "I follow you", i.e., in all directions of gazes, the squinted eye follows the normal (fixating) eye with same degree of angle of squint. In this, primary angle is equal to secondary angle. Primary angle is angle of deviation of squinted eye when normal eye fixates. Secondary angle is angle of deviation of normal eye (under cover) when squinted eye is made to fixate by covering the normal eye.
