The most common visual field defect is homonymous hemianopia due to a retrochiasmic lesion, reported in 30% of adults after stroke and in 60% after posterior arterial stroke (9)(10) (11).

This occurs in approximately 8% of all strokes.3 Homonymous hemianopia is a loss of the right or left halves of the visual field of both eyes (Figure 1a, 1b) and usually occurs as a result of a middle cerebral or posterior cerebral artery stroke affecting either the optic radiation or
