Study of primary convergence insufficiency.

ABSTRACT

The present study was done to find out the incidence of primary insufficiency of involuntary convergence and evaluate the relative efficacy of synoptophore treatment against home exercise in its management. During the period of study, 2162 cases in the age group 15 to 35 years were studied for convergence in detail. It was found out that the incidence of primary convergence insufficiency is quite high (7.7% of total orthoptic clinic attendance). It commonly affects those who are constantly engaged in near work. Response to synoptophore exercises and home exercises is comparably equal. Recurrence of the ailment after stopping the exercises is not uncommon.
