Bilateral lesions of the primary visual cortex may cause cortical blindness. Patients have no vision but the response of the pupil to light is intact (as the reflex does not involve cortex. Fundoscopy is normal. Cortical blindness can be associated with denial of visual loss, when it is known as Anton's syndrome.
