Cortical blindness syndrome Dr Rohit Sharma and Daniel Loh et al. Cortical blindness is a condition resulting from lesions in the primary visual cortex (V1) characterized by visual impairment but with an intact anterior visual pathway (normal pupillary reflexes and fundal appearance).

David Milner Melvyn A. Goodale Publisher: Oxford University Press Generally none: Cortical blindness results from failure of the brain interconnections to the visual cortex to develop, or damage directly to the cortex from injury and vascular catastrophe. No treatment is possible. Such persons should be entered into programs for the blind and poorly sighted to develop alternate means of coping. 1981-02-01 Transient cortical blindness after coronary angiography has long been reported in the literature; however, this condition remains rare until today. We report a case of transient cortical blindness after coronary angiography, bypass graft angiography, and coronary angioplasty, which was deemed to be secondary to contrast agent.

It has an incidence of 0.3–1% following cerebral angiography (); a slightly higher incidence is reported with vertebral angiography (). Cortical blindness is the total or partial loss of vision in a normal-appearing eye caused by damage to the brain's occipital cortex. Cortical blindness can be acquired or congenital, and may also be transient in certain instances. This resulted in persistent cortical blindness (Anton’s syndrome). PRES has only rarely been reported in relation to SARS-CoV-2 infection and no patients have developed persistent cortical blindness. We summarise the clinical presentation of the patient and review the current literature. Hemianopsia, cortical blindness and ophthalmoplegia may be present.

Cortical visual impairment (CVI), and cerebral visual impairment (CVI), are terms often used to describe visual impairment that occurs because of injury to the brain, as are neurological vision loss, and vision loss due to traumatic brain injury (TBI). Although vision or sight, as a sense, is primarily associated with the eyes, in reality, vision is the product of a complex system of which the eyes are only one part.
Cortical blindness is a part of cerebral blindness which is defined as loss of vision secondary to damage to the visual pathways posterior to the lateral geniculate nuclei. Cortical visual impairment (CVI), and cerebral visual impairment (CVI), are terms often used to describe visual impairment that occurs because of injury to the brain, as are neurological vision loss, and vision loss due to traumatic brain injury (TBI).
Cerebral visual impairment (CVI), is defined as vision loss resulting from damage to retrogeniculate pathway, in the absence of any ocular pathology, with increased survival of preterm babies and better perinatal care, CVI has emerged as one of the leading cause of visual impairment. Other causes of visual impairment reported in children with multiple disabilities may be secondary to ocular defects such as uncorrected refractive errors, cataract, nystagmus, retinopathy of prematurity (ROP),

(partial cortical blindness).
Ann Neurol 21:149-158, 1987 Cortical or cerebral blindness (CB) refers to loss of vision produced by lesions affecting geniculocalcarine visual pathways.

It is now widely accepted that "cortical blindness" is not an appropriate diagnostic term for children with early, acquired visual impairment due to non-ocular causes. Cortical blindness is a part of cerebral blindness which is defined as loss of vision secondary to damage to the visual pathways posterior to the lateral geniculate nuclei. Description of CB goes back to the Roman era. ered to have had cortical blindness if severe bilateral homonymous visual deficits had developed that lasted longer than 24 hours, and if there were reactive pupils and no evi- dence of an ocular or psychogenic cause of blindness.
Cortical blindness does not have specific treatment, since it is the result of the destruction of the cerebral elements that allow visual processing. The exception would be those cases in which the cause was a dysfunction of the occipital cortex generated by some treatable cause, such as an infection, as long as the brain tissue has not died.

Cortical Blindness is a visual impairment caused by damage to the visual systems in the brain (visual cortex) which deal with processing and integration of visual information. There is an impairment of visual functioning even though the eyes are anatomically and structurally intact.
