Active vision in sight recovery individuals with a history of long-lasting congenital blindness.

ABSTRACT: What we see is intimately linked to how we actively and systematically explore the world through eye movements. However, it is unknown to what degree visual experience during early development is necessary for such systematic visual exploration to emerge. The present study investigated visual exploration behavior in ten human participants whose sight had been restored only in childhood or adulthood, after a period of congenital blindness due to dense bilateral congenital cataracts. Participants freely explored real-world images while their eye movements were recorded. Despite severe residual visual impairments and gaze instability (nystagmus), visual exploration patterns were preserved in individuals with reversed congenital cataract. Modelling analyses indicated that similar to healthy co
