When one eye turns inward, outward, upward, or downward, two different pictures are sent to the brain. Thus, the brain can no longer fuse the two images coming from the two eyes. This causes loss of depth perception and binocular vision. The term is from Greek exo meaning "outward" and trope meaning "a turning". [1]
Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...
Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. [1] Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues ...
If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth perception. [3] If onset is during adulthood, it is more likely to result in double vision. [3] Strabismus can occur due to muscle dysfunction (e.g., myasthenia gravis [4] [5]), farsightedness, problems in the brain, trauma, or infections. [3]
Spatial-D and G-force induced loss of consciousness (g-LOC) are two of the most common causes of death from human factors in military aviation. [9] A study on the prevalence of spatial disorientation incidents concluded that "if a pilot flies long enough ... there is no chance that he/she will escape experiencing at least one episode of ...
Derealization is an alteration in the perception of the external world, causing those with the condition to perceive it as unreal, distant, distorted or in other words falsified. Other symptoms include feeling as if one's environment is lacking in spontaneity, emotional coloring, and depth. [ 1 ]
Coloboma can cause vision loss and sensitivity to light, which Nedoroscik has also posted about. What causes strabismus? An estimated 2% to 5% of the general population —or 5 to 15 million ...
The sensory disorientation of returning from a prolonged banking turn to wings-level flight can cause the pilot to re-enter the banking turn, as in the graveyard spin illusion. While the plane continues in the turn and begins to indicate a loss of altitude, the pilot will try to correct the loss of altitude by "pulling up" on the plane's controls.
