The most common cause of cortical blindness is ischemia (oxygen deprivation) to the occipital lobes caused by blockage to one or both of the posterior cerebral arteries. [2] However, other conditions have also been known to cause acquired and transient cortical blindness, including: Congenital abnormalities of the occipital lobe [5]
Congenital blindness is a hereditary disease and can be treated by gene therapy. Visual loss in children or infants can occur either at the prenatal stage (during the time of conception or intrauterine period) or postnatal stage (immediately after birth). [3] There are multiple possible causes of congenital blindness.
Children that are enrolled presently usually developed blindness 5 or more years prior to enrollment, consequently not reflecting current possible causes. [28] About 66% of children with visual impairment also have one other disability (comorbidity), be it, intellectual disabilities, cerebral palsy , or hearing loss . [ 29 ]
CVI is also sometimes known as cortical blindness, although most people with CVI are not totally blind. The term neurological visual impairment (NVI) covers both CVI and total cortical blindness. Delayed visual maturation, another form of NVI, is similar to CVI, except the child's visual difficulties resolve in a few months.
The visual changes in PRES may include hemianopsia (inability to see the left or right part of the visual field), blurred vision, lack of visual awareness on one side, visual hallucinations, and cortical blindness. [1] Seizures occur in about two thirds of cases with seizures being the initial symptom in about 50% of cases.
Semaglutide, the active ingredient in Ozempic and Wegovy, has become a hugely popular medication thanks to its effectiveness for weight loss. But a growing body of research has linked the ...
Parinaud's syndrome is a constellation of neurological signs indicating injury to the dorsal midbrain. More specifically, compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF).
People taking Ozempic and Wegovy may be at increased risk of developing a debilitating eye condition that can cause irreversible vision loss, a study published in JAMA Ophthalmology finds.
