Purpose: This study investigated the effects of visual rehabilitation on binocular visual function in kindergarten children with developmental delay. Methods: This study comprised a case series tracking changes in binocular visual function in three children with developmental delay during rehabilitation. The rehabilitation schedule was tailored to the specific circumstances of each child and was divided into three phases—baseline, intervention, and maintenance—aiming to observe the impact of rehabilitation on visual performance. Results: All three children presented with pre-existing visual deficits—including amblyopia, strabismus, and oculomotor dysfunction—which were associated with functional challenges such as frequent falls, postural instability, and reading difficulties. Following the multidisciplinary rehabilitation program, marked improvements were observed in visual acuity, accommodative facility, and stereopsis. Furthermore, parents reported a decrease in daily functional challenges, with these gains being sustained during the post-intervention follow-up. Conclusions: This case series suggests that structured visual rehabilitation may improve binocular function and daily performance in children with developmental delays. These findings underscore that visual ability extends beyond mere visual acuity, highlighting the necessity of assessing multidimensional visual functions in special education and rehabilitative practice.
