[A comparative study of the difference in the evolution of refraction in the two eyes in patients with convergent strabismus (author's transl)].
In 329 cases of concomitant convergent strabismus, the alterations of refraction in the two eyes were compared over periods ranging from 10 to 30 years. In the group with unilateral strabismus (245 cases), a significant difference between the two eyes was observed. The change of refraction, if any, in the non-fixing eye (emmetropization or myopization) clearly lagged behind that in the fixing eye. This difference was particularly pronounced in the cases showing myopization. In the group with equivalent function of both eyes--alternating strabismus and cases with complete normalization, including functional normalization--a total of 84 cases, any emmetropization or myopization was found to run practically parallel in the two eyes. This shows that it is true of refraction, also that the genetically determined evolutive pattern may be modified by a functional abnormality.
