RESUMO
We retrospectively studied 60 amblyopic patients who had been treated for 12 months or more. They were divided into three age groups; below 5.5 years, 5.5 years to 8 years and 8 years or more, and visual improvements were compared with three age groups. The visual improvements were 5 line increase in both of below 5.5 year group and 5.5 year to 8 year age group and 3 line increase in 8 year and older group. In all three age groups, two-thirds of the improvements were achieved during the first three months of treatment There was no difference in visual improvement according to amblyopic type(strabismic, anisometropic, strabismic and anisometropic amblyopia). Treatment failures seemed to be the later onset of treatment, eccentric fixation and large anisometropic difference.
