ANATOMY

Detailed explanation-1: -The Rochester team found that survivors of occipital strokes-strokes that occur in the occipital lobe of the brain and affect the ability to see-may retain some visual capabilities immediately after the stroke, but these abilities diminish and eventually disappear permanently after approximately six months.

Detailed explanation-2: -When the occipital lobes of the brain are completely affected by a stroke, it causes total vision loss. This is called “cortical blindness.”5 It means the vision loss was caused by damage to the cortex of the brain. Some occipital stroke survivors have a condition called visual anosognosia .

Detailed explanation-3: -Damage to the occipital lobe results in complete or partial blindness or visual agnosia depending on the location and severity of the damage. Vision begins with the spatial, temporal, and chromatic components of light falling on the photoreceptors of the retina and ends in the perception of the world around us.

Detailed explanation-4: -The occipital lobe is the visual processing area of the brain. It is associated with visuospatial processing, distance and depth perception, color determination, object and face recognition, and memory formation.

Detailed explanation-5: -Injury to the occipital lobes may lead to vision impairments such as blindness or blind spots; visual distortions and visual inattention. The occipital lobes are also associated with various behaviors and functions that include: visual recognition; visual attention; and spatial analysis.
