Cortical Blindness

Cortical blindness is visual loss resulting from bilateral occipital lobe damage, with intact ocular structures and pupillary reflexes. Etiologies include ischemic stroke, hypoxia, trauma, and infection. Patients may demonstrate Anton syndrome, denying blindness despite profound deficits. Diagnosis is clinical, supported by neuroimaging showing occipital lesions. Management is supportive, addressing underlying cause, rehabilitation, and compensatory strategies; prognosis varies with etiology and extent of cortical injury.
