In medicine, a hemianopsia is a neurological sign (medical) on physical examination that is "partial or complete loss of vision in one half of the visual field(s) of one or both eyes."[1]
Classification
Subtypes include:
- Altitudinal hemianopsia, "characterized by a visual defect above or below the horizontal meridian of the visual field."[1]
- Homonymous hemianopsia "refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field."[1]
- Binasal hemianopsia "consists of loss of vision in the nasal hemifields of both eyes."[1]
- Bitemporal hemianopsia is the "bilateral loss of vision in the temporal fields."[1]
