ASSOCIATION BETWEEN REFRACTIVE ERRORS AND CONVERGENCE INSUFFICIENCY

Abstract

Objectives: Objective of the study was to find out association of refractive errors with convergence insufficiency and to find the effect of convergence insufficiency on refractive errors. Method: The patients were selected on the basis of refractive error associated with convergence insufficiency from refraction room of outpatient department Mayo hospital Lahore. Near point of convergence was measured by using RAF rule in those patients who had refractive errors i.e. myopia, hyperopia and astigmatism. Persons who had no refractive error, who were not co-operative were not included in this study. Result: Convergence insufficiency was found more in hyperopic patients than in myopic and astigmatic patients. Conclusion: Convergence insufficiency was seen more in hyperopes than in myopes and astigmatic patients. These data and whole study supports the assumption that screening programs in our country could be useful in detecting and minimizing the visual disturbances due to convergence insufficiency.
