Neuro-optometry Seminar: Cortical Blindness and Charles Bonnet Syndrome

Cortical blindness is characterized by impaired vision resulting from an insult to the visual cortex. Patients with cortical blindness will often present with healthy ocular structures and normal pupils, but best-corrected vision will be count fingers or worse. Cortical blindness should be suspected in cases of sudden unexplained vision loss, especially in older patients who are at risk for stroke.
