Visual field loss occurs as a result of damage to the optic pathway, which can involve various regions such as the optic nerve, optic chiasm, or visual cortex. This condition can manifest in different ways, such as homonymous hemianopia, where there is loss of vision in the same visual field of both eyes, or quadrantanopia, where a quarter of the visual field is lost.

This type of visual impairment significantly impacts various visual functions, hampering a person’s ability to navigate their environment, safely drive, and participate in regular daily activities. Individuals with visual field loss may be unaware of the areas that are not visible to them, which can lead to safety concerns and challenges in rehabilitation.

In contrast, visual midline shift refers to a misperception of the midline and is more about spatial awareness than a direct loss of visual field. Diplopia is characterized by double vision and is primarily related to issues with eye alignment or muscle function rather than the optic pathway itself. Strabismus involves misalignment of the eyes and can lead to visual complications, but it isn't directly caused by damage to the optic pathway.
