OPHTHALMOLOGISTS are asked at some point to do an eye examination on nearly every child who has an academic deficiency. The most prevalent and worrisome of these academic deficiencies involves reading and has been given the name dyslexia.
It is unfortunate, however, for those prone to demand a simple, logical solution to the dyslexia problem that the eyes have been found to have little significance in reading disorders. While uncorrected refractive errors and symptomatic phorias can hinder reading and should be treated, treatment of trivial eye malfunctions in the hope of improving reading has been found to be ineffective.
Dyslexia exists, however, and ophthalmologists cannot in the best interest of their patients ignore the issue.
Dyslexia may be classified as follows: (1) primary specific developmental dyslexia; (2) secondary endogenous dyslexia; and (3) exogenous reading disability. The final category is not considered a true form of dyslexia.
Primary, specific developmental dyslexia
