The Relationship Between Convergence Insufficiency and School Achievement

Key Points

This research aims to explore the link between convergence insufficiency and academic performance in schoolchildren.
Examined convergence ability in 735 schoolchildren aged 7 to 14
Classified subjects based on objective and subjective near point of convergence measurements
Analyzed data considering age, sex, and IQ
9% of children had an objective near point of convergence over 10 cm
10% had a subjective near point of convergence exceeding 10 cm
No significant differences in school performance related to convergence insufficiency based on their mother tongue and grade point average

Abstract

Abstract Schoolchildren (735) between the ages of 7 and 14 were examined for convergence ability. Nine percent had an objective near point of convergence of more than 1 0 cm and 1 0% had a subjective near point of convergence of more than 10 cm. The recovery point was greater than 15 cm for 9% of the subjects when measured objectively and 1 2% subjectively. The sample was analyzed with regard to age, sex, and IQ. There was no significant difference between children who showed convergence insufficiency and those who did not with regard to school results in their mother tongue and in their grade point average.
