The association of reading disability with perceptuomotor problems has had a chequered history. This study examines the relationship between a new test of ocular dominance and reading and spelling ability in a group of 298 schoolchildren. Similar rates for unstable ocular dominance were found for poor readers as in comparable studies. The rates of unstable ocular dominance did not differ between the 'dyslexics' and the controls. These findings in a blind study question the role of this test as a diagnosis of 'dyslexia.'
