What condition is characterized by a loss of visual field on the same side in both eyes?

The condition characterized by a loss of visual field on the same side in both eyes is homonymous hemianopia. This condition typically arises from damage to the optic tract or the visual pathways beyond the optic chiasm and results in a loss of vision in the same field (either right or left) in both eyes. For instance, if the right hemisphere of the brain is affected, a person will lose the right field of vision in both eyes. This symmetry in the visual field loss is a key feature of homonymous hemianopia, distinguishing it from other visual field defects.

Monocular blindness refers to the loss of vision in only one eye, which does not fit the criteria of visual field loss in both eyes. Quadrantanopia involves the loss of vision in a quarter section of the visual field, which may affect only one eye or both, but does not describe a complete sided loss like in homonymous hemianopia. Scotoma denotes a localized area of reduced vision or a blind spot in the visual field, but again, this does not correlate with the uniformity of side-specific loss found in homonymous hemianopia. Thus, homonymous hemianopia clearly stands out as the correct answer regarding the condition defined in the question.
