Given the rapid increase in endovascular procedures used to treat cerebral aneurysms, we explored the prevalence of this complication and whether we could add to the understanding of this disorder. Destruction of the primary visual cortex leads to blindness in the part of the visual field that corresponds to the damaged cortical representation. The area of blindness – known as a scotoma – is in the visual field opposite the damaged hemisphere and can vary from a small area up to the entire hemifield. 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), The disruption in the visual pathway in the brain results in false complex visual messages being delivered to the vision centers in the brain. A stroke in any of the vision areas of the brain can cause Charles Bonnet syndrome, but most often, it is caused by a stroke of one or both occipital lobes.

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.

Cortical blindness (CB) defined as loss of vision without any ophthalmological causes and with normal pupillary light reflexes due to bilateral lesions of the striate cortex in the occipital lobes. 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).
