Results in Binocular Vision by Early Operation in Esotropia

Abstract

One of the few things in the squint-therapy upon which we all agree is that the therapy that to day is the usual is most unsatisfactory in its results.If we put the squinters to between 2 and 4 per cent of the population and realize that by far the greater number of them, with or without treatment, go out into life without binocular vision and a great many with unilateral amblyopia it is evident that the problem here discussed is one of first order.In the following suggestions for treatment I omit the orthoptic treatment not because I wish to give judgment on thc method but because I am of opinion that the orthoptic treatment can hardly be practised in countries with great distances and a slender population.It also ought to be considered that the orthoptic treatment can only be put into practice at a point of time when amblyopia and suppression and anomalous correspondence already are apparent and consequently will have to affect the final result.According to recent points of view both the visual acuity and the binocular vision are qualities under development during early infancy.Duke Elder divides the squint-amblyopia into a part caused by prevention of natural development -the same amblyopia *) Received may 25th 1952.
