What is alternating esotropia?

All motion in every direction is stopped when the light is moved across the pupil
The patient fixates with only one eye while the other eye turns in
The area of the space visible to the eye
Perimetry

The correct answer is: The patient fixates with only one eye while the other eye turns in

Alternating esotropia is a type of strabismus where one eye turns in while the other eye fixates. This means that the patient goes through periods where each eye takes turns turning in towards the nose. This condition is different from constant esotropia where one eye is consistently turned towards the nose. In alternating esotropia, the eyes take turns being the eye that is straight and the eye that is turned. This condition is often managed through a combination of glasses, vision therapy, and sometimes surgery to align the eyes properly. The other options are not correct: A. The description provided does not match the characteristics of alternating esotropia. C. This defines the term visual field, which is the total area in which objects can be seen in the peripheral and central vision while the eyes are fixed. D. Perimetry is a type of visual field testing method used to map out any blind spots in a patient's vision.
