Abstract

Purpose: To study the effect of colored filters on the reading ability in dyslexic children. Methods: A total oftwelve dyslexic children and twelve age and gender matched non-dyslexic children were administered. Following examinations were performed for participants: visual acuity assessment, refraction, evaluating far and near heterophoria, measuring near point of convergence and accommodation, stereopsis, and near fusional reserves. Reading ability was assessed with colored filters and transparent in dyslexic patients. Colored filters were chosen based on Wilkins method (X1 to X16). Filter which improved the reading ability was recorded. Results: Significant reduction in fusional reserves in dyslexic children compared to normal individuals were observed. (Base in Break p=0.02, Base in recovery, Base Out Break and Base Out recovery p<0.001) However, other visual functions did not differ significantly between the dyslexic and control groups. Colored filters significantly improved word reading ability of dyslexic children. (p=0.0036) Conclusion: Our findings showed a reduction in fusional reserves in dyslexic children. Reading ability significantly increased in dyslexic children using color filters.
