In a left esotropia, the left eye 'squints', and in a right esotropia the right eye 'squints'. In an alternating esotropia, the patient is able to alternate fixation between their right and left eye so that at one moment the right eye fixates and the left eye turns inward, and at the next the left eye fixates and the right turns inward. This ...
The 2 red lights from the right eye are seen on the right side; The 3 green lights from the left eye are seen on the left side; This is recorded as: W4LT (D): 5 lights (Uncrossed Diplopia) ET NB: The clinician will be unable to indicate which eye is the deviating eye based on these results alone.
Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes.
A person with an intermittent right esotropia has a right eye that occasionally drifts toward the person's nose, but at other times is able to align with the gaze of the left eye. A person with a mild exophoria can maintain fusion during normal circumstances, but when the system is disrupted, the relaxed posture of the eyes is slightly divergent.

The word monocular comes from the Greek root, mono for single, and the Latin root, oculus for eye. Bimonocular vision , also named two-eyed monocular vision, is known as seeing and using both eyes in a monocular way independently of each other without fusion over the entire field of view without visual field loss in the human species [ citation ...

The presence of the blind spot scotoma can be demonstrated subjectively by covering one eye, carefully holding fixation with the open eye, and placing an object (such as one's thumb) in the lateral and horizontal visual field, about 15 degrees from fixation (see the blind spot article). The size of the monocular scotoma is 5×7 degrees of ...
