Final answer:
Tunnel vision in the healthcare context refers to a cognitive bias where a healthcare provider focuses only on a single aspect of a patient's condition. This differs from the medical condition of tunnel vision, which is a loss of peripheral vision while central vision remains, potentially due to pressure on the optic chiasm from a pituitary growth.
Step-by-step explanation:
The phenomenon where you become focused on one aspect of the patient's condition and exclude all others is known as tunnel vision. It is a bias in clinical judgment and decision-making that can limit a healthcare provider's ability to assess the patient holistically. This is different from an actual visual impairment. In the context of visual system problems, tunnel vision can also specifically refer to a condition where only the central visual field is perceived, and the peripheral vision is lost, which could, for example, be due to a growth in the pituitary gland affecting the optic chiasm and not the axons projecting to the same side of the brain.
