Abstract

Cerebral visual impairment (CVI) is a complex neurodevelopmental disorder that leads to visual impairment due to damage in the brain. The clinical features of CVI can include light gazing, preferences for certain movements, selective visual field preferences, inability to reach for objects using vision, and poor eye contact. In our presented cases, we observed the heterogeneity of CVI, which resulted in variable outcomes among the subjects. Out of the three cases, two demonstrated significant improvement. The one case that showed less improvement may be attributed to uncontrolled seizures despite treatment with multiple antiepileptic medications. Vision therapy, which utilizes colourful, high-contrast objects along with multisensory cues such as tactile and auditory stimuli, has been shown to enhance vision. These methods can promote visual interest, which is the engagement of the visual system and the development of attention. As a result, vision therapy can help children with CVI maximize their visual potential.
