What is described as a disturbance in vision affecting half of the visual field in both eyes?

• A. Hemiplegi
• B. Amaurosis duplex
• C. Homonymous hemianopia
• D. Dysphagia

Answer: (C)

Homonymous hemianopia is characterized by a disturbance in vision where the same half of the visual field is affected in both eyes. This often occurs due to damage to the optic pathways, particularly after a stroke or injury that impacts the areas of the brain responsible for processing visual information. Specifically, this type of vision loss can manifest as the inability to see the left or right side of the visual field in both eyes, depending on the location of the brain lesion. For example, if the right optic tract is damaged, the person would experience a loss of vision on the left side of their visual field. Understanding homonymous hemianopia is crucial for diagnosing related neurological conditions and determining the proper interventions and therapies for affected individuals. This distinction is important in the field of vascular specialization and can significantly impact a patient’s overall functionality and quality of life.
