Homonymous hemianopia (HH) is a visual field defect characterized by the involvement of two right or left halves of the visual
field in both eyes. Patients with HH complain of difficulties with reading and scanning scenes in sufficiently rapid fashion to
make sense of things as a whole. Some of these patients are not aware of their visual field defect.
We report two cases of left-sided hemianopia in which visual field defects were detected “quite” accidentally. In the case of the
first patient, revealing HH facilitated the detection of brain tumor and its treatment. In the case of the other patient, identifying
HH, which was caused by a head injury, and making the patient aware of this fact, prevented potential harmful consequences
associated with driving a car by a person with severe deficits in cognitive visual functions.
