A guide to the ophthalmologist in the choice of the older child with amblyopia most likely to respond to active intensive visual stimulation in short bursts is presented. A series of 99 children treated on a CAM vision‐stimulator is described. Visual improvement of at least two rows of letters on the Snellen chart was maintained for at least three years after treatment in 62% of these patients aged between five and nine years with visual fixation within 3 ° of the fovea. Amblyopia following minor trauma or minor pathology also responded well. Children maintaining the visual improvement were those with esophoria up to 13 ° . those with hypermetropia up to 11.0 D and those with astigmatism of 1.5 D. Also responding well were children with anisometropia with up to 3.0 D of either hypermetropia or astigmatism
