Which condition results in blindness of half of the visual field following a CVA?

• A. Diabetic retinopathy
• B. Hemianopsia
• C. Macular degeneration
• D. Cataracts

Answer: (B)

Hemianopsia is a condition characterized by the loss of half of the visual field in one or both eyes. This typically occurs as a result of a cerebrovascular accident (CVA), commonly known as a stroke, which can damage specific areas of the brain that process visual information. The extent of the visual field loss depends on the location and severity of the brain damage.

In cases of hemianopsia, individuals may experience either right-sided or left-sided visual field loss, depending on which hemisphere of the brain was affected. This condition can significantly impact a person's ability to navigate their environment and perform daily activities, making early intervention and rehabilitation essential for functional recovery.

Other conditions listed, such as diabetic retinopathy, macular degeneration, and cataracts, are related to eye health and vision impairment but do not specifically result in the hemianopsia associated with a CVA. Each of these conditions affects vision in different ways, often related to the structure of the eye rather than the brain's processing of visual information. Thus, hemianopsia is the direct result of neurological damage from a stroke, distinguishing it from the other visual impairments.
