De Wecker proposes that the treatment of squint should differ according as one wishes to obtain binocular vision or merely a cosmetic effect. From statistics of 3002 cases of squint he endeavors to find the proportion in which binocular vision is restored. The cases of alternating strabismus with good vision in each eye are the most favorable.
The periodic squint of hyperopes with good vision in both eyes is cured and binocular vision is restored by using correcting glasses, or there may be spontaneous recovery. When the vision of the squinting eye is less than ¼, one cannot count upon obtaining binocular vision. This is also the case in periodic squint of myopes, surgical interference here being necessary and often difficult to carry out successfully. In the most frequent form of squint, permanent unilateral squint, binocular vision is secured in only about one fourth of the cases. It is, furthermore, unnecessary to bother these patients with visual exercises in case the squinting eye has very poor vision.
