Abstract

Purpose: The Convergence Insufficiency Symptom Survey (CISS) has been validated to aid in the diagnosis of convergence insufficiency in both children and young adults. Convergence excess (CE) share some common symptoms with CI. The purpose of this study was to assess the validity of CISS in evaluating visual symptoms in young adults with CE.

Methods:  A total of 179 optometry students were enrolled. Ninety four of them had normal binocular vision (NBV), 66 had CE, and 19 had CE as well as accommodation insufficiency (AI). An analysis of variance was performed to compare the CISS scores among NBV, CE, and CE plus AI groups.

Results:The average age of the subjects was 22.55 years, ranged from 20.00 to 35.40 years. The mean (± SD) CISS scores were 12.24 ± 7.79 (NBV), 16.71 ± 10.83 (CE), and 19.74 ±10.93 (CE plus AI). A significant difference was detected among NBV, CE, and CE plus AI groups (P

Conclusions: Young adults with CE had a significantly higher CISS score than those with NBV. Although there was a trend that young adults with both AI and CE had a higher CISS score than subjects with only CE, however without statistical significance. The results of this study demonstrate that the CISS can be used to evaluate visual symptoms in young adults with CE.
