Etiology - Strabismus, commonly known as "cross eyes," can be caused by many things, such as eye muscle imbalances, neurological disorders, refractive errors, genetics, or vision loss.
Symptoms - Eyes moving out of sync, noticeable eye drift, squinting/tilting of the head, and overall difficulty with visual tasks.
Details - Strabismus occurs when the eyes do not work in unison tracking a singular object. This visual imablance then leads to noticeable eye misalignment.
Treatment - The best way to treat strabismus is to force the eyes to align and work together, but the exact methodology can vary on a case-by-case basis. Common treatment approaches include corrective lenses, patching of the stronger eye, medication, vision therapy, and even surgery.
