What condition is characterized by repetitive, uncontrolled eye movements?

The condition characterized by repetitive, uncontrolled eye movements is nystagmus. This condition involves involuntary eye movements that can be horizontal, vertical, or rotary. These movements may occur when a person is looking in a certain direction or even at rest. Nystagmus can result from various factors, including neurological conditions, inner ear disturbances, or can be congenital in nature.

In contrast, strabismus refers to a misalignment of the eyes, which can cause one eye to turn in, out, up, or down. While strabismus can lead to issues with depth perception and vision, it is not defined by repetitive eye movements.

Diplopia, or double vision, involves seeing two images of a single object, which is primarily related to issues with the eyes' alignment or function but does not involve repetitive movements.

Vision loss broadly describes a decrease in the ability to see, which can occur for many reasons but does not pertain to the defined movements of the eyes typical of nystagmus. Thus, nystagmus is the most accurate description of the condition involving repetitive, uncontrolled eye movements.
