Eye metrics often reflect visual conscious awareness, conscious content, and neural processing in cerebral blindness.

ABSTRACT: Cerebral blindness is caused by damage to the primary visual pathway. Some people with cerebral blindness retain degraded vision and non-visual sensations and can perform visually guided behaviors within their blind visual field. These cases raise questions about visual conscious perception and residual neural processing in cerebral blindness. A major challenge in this research is that subjective reporting on experiences in the blind field can be unreliable. Alternatively, eye metrics offer a promising objective marker of conscious awareness, conscious content, and brain activity. In this study, we recorded visual stimulus-evoked pupil size, blink, and microsaccade responses in neurotypical participants and both the sighted and blind fields of cerebrally blind participants.
