Haddad, Herskel M.; And Others – Journal of Learning Disabilities, 1984
In 73 children (6-13 years old) with reading difficulty, ophthalmological evaluation showed that 18 had overt refractive errors, 18 dyslexia and no ocular anomalies, and 37 impaired fusional amplitudes, 24 of whom were dyslexic. In all Ss with poor fusional amplitudes the reading mechanism could be improved with orthoptic exercises. (Author/CL)
