The majority of laymen and a great many of our professional brethren regard squint with a great deal of indifference. This arises largely from the prevalent idea that the child will outgrow it, is too young to be treated or, if treated, will have to always wear glasses. Yet when children grow up with this horrible deformity, they and their parents often seek for relief without success. What I wish to try to make clear is the fallacy of the above reasons, why the squinting eyes of children should be attended to as soon as the first appearance of even a tendency to squint is noticed.
In rare instances in some cases the squint disappears as the patient grows older, but nearly always with vision much impaired in the deviating eye and binocular vision very imperfectly developed.
The earlier one can get a case after he has commenced
