Vision is an automatic act, it keeps us aware of our environment to react before a danger or an opportunity. When we want to get more information, we concentrate our minds and our eyes over an object or situation, in a more conscious and active way.  After analyzing an

Tunnel vision is a cognitive bias associated to radiology when a finding preclude a total observation of the visual field missing an important piece of information. A similar situation could happen when a surgeon focused his or her intervention over a segment without a complete physical or functional review of the anatomical area involved.

Two narrative examples will help to understand this concept.. Continue reading Tunnel vision in surgery: looking for anatomy
