Purpose: This study is to evaluate between convergence insufficiency and grades of elementary school students.
Methods: Objective refraction were measured for 244 elementary school students in Mokpo. Symptoms using CISS (convengence insufficiencey symptom survey), which consists of 0~4 point scale performed, were compared between normal binocular vision and convergence insufficiency. Also, correlation between symptoms by CISS and academic grades was analysed in normal binocular vision group and convergence insufficiency group.
Results: Elementary school students with convergence insufficiency were 52 among total of 244 participants. The mean scores of CISS were 5.76±1.13 for the normal binocular vision group, and 26.21±1.06 for convergence insufficiency group. There were significantly negative correlation between scores of CISS and academic grades in normal binocular vision group (r = ?0.121) and convergence insfficiency group (r = 0.040).
Conclusions: Academic grade was lower of the convergence insufficiency group of elementary school students than of normal binocular vision elementary group.
