The eye is very complex and contains various tissues and structures that work together to provide vision.
Eye problems can range from benign, self-resolving processes to malignant, and possibly metastatic
tumors. Eye disorders can be caused by various factors, resulting in various signs and symptoms. They
can be as trivial as minor irritation or pain all the way to blurred vision or blindness. Strabismus is a
visual disorder in which the eyes are misaligned and point in different directions. When the eyes are
misaligned, typically one eye will fixate on objects of interest while the other eye turns in (esotropia), out
(exotropia), down (hypotropia), or up (hypertropia).
