THIS paper is a preliminary report on the prognosis and treatment of a number of patients with ametropia, with vision ranging from 20/40 to 20/70 (amblyopic types) and higher refractive errors. All these patients had no definite pathologic condition of the eyes to account for the low vision, nor could the visual defect be corrected with glasses.
With the routine treatment as practiced in the clinic, if the patient was a young child, the mother was advised either to use atrophine or to keep a continuous patch on the good eye, depending on the degree of amblyopia. The purpose of this measure was to encourage the eye with the poorer vision to function properly. If with this treatment several months elapsed with no visual improvement, the case was placed in the category of congenital amblyopia, with its accompanying poor prognosis.
Occasionally the patient was unaware of his poor vision because
