Impact of Refractive Error Correction on Mental and Visual Development in Children with Global Developmental Delay

Abstract

ABSTRACT Introduction: Primary cause of GDD is irreversible, but secondary factors like visual defects, auditory factors etc., are amenable to treatment, and benefit from intervention (Bader 1980). According to a study by Salt (2014), of the various ocular manifestations, refractive error was the most common (20-60%). There is a dearth of studies on the quantification of DQ improvement, on behavioral improvement, due to visual improvement. Hence, the study was attempted. Objectives: To study the impact of early Refractive Errors correction, on Vision, Developmental Quotient (DQ) and their determinants in GDD children of age 1 to 5 years.
