What condition does homonymous hemianopsia refer to?

Homonymous hemianopsia is a neurological condition resulting from damage to the optic pathways in the brain, typically due to strokes, tumors, or injuries affecting the visual processing areas. This condition is characterized by the loss of the same visual field (either the left or the right side) in both eyes. Thus, when a person suffers from homonymous hemianopsia, they might lose their right visual field in both eyes or their left visual field in both eyes, leading to a significant impairment when trying to navigate their surroundings or perform visual tasks.

The definition highlights that this loss is not limited to one eye but is symmetrical, affecting both eyes in the same manner. Understanding this characteristic is crucial, as it helps to differentiate it from other visual field losses, such as those involving peripheral or inferior vision, which have different implications and presentations.
