H51: Other disorders of binocular movement

Other disorders of binocular movement, as the name suggests, refers to a group of conditions that disrupt the coordinated movement of both eyes. This disturbance can lead to problems such as the eyes repeatedly crossing or drifting apart, which can affect vision and perception of depth. These disorders usually arise from issues with the muscles that control eye movement or the nerves that control these muscles. Symptoms often include blurred vision, double vision, or trouble focusing, especially when viewing objects at different distances or switching focus between near and far objects. Progression of these disorders can vary, sometimes causing frustration, disability, or social embarrassment. They can affect anyone but are typically seen more often in children and older adults. The system primarily impacted is the visual system - specifically, the muscles controlling eye movement and the associated nerves.
