Divergent gaze: Exotropia (aka divergent gaze) can have a congenital or acquired basis. If it is recent onset a medical evaluation is important to rule out diabetic , hypertensive or other neurologic etiology. An ophthalmic evaluation would be a first and important step. Muscle alingment. Or strabismus surgery can help restore this to straigten eye gaze.
