Intermittent exotropia: In this type, one eye sometimes drifts outward while the other stays focused. The eyes may trade off positions or the same eye may wander every time. Infantile esotropia:This happens in infants, before age 6 months, without farsightedness. One or both eyes can turn ...
Case 3 This 48-year-old woman had a history of having undergone multiple prior strabismus surgical procedures for what she thought was intermittent exotropia; prior records were not available. She had been asymptomatic for many years, but when she became presbyopic and needed a bi...
What is exotropia strabismus? What is bilateral refractive amblyopia? Does posterior vitreous detachment cause headaches? Is there treatment for the thinning of the optic nerve? What is a traumatic macular hole? What do ophthalmologists do to diagnose retinitis pigmentosa?
This is called a phoria, which is a variable, intermittent type of strabismus (eye misalignment). Another fatigue-related misalignment is convergence insufficiency, which is the inability to keep the eyes converged (slightly crossed) for long periods while reading. This can often be alleviated with...

Strabismus can be present at all times or intermittent, meaning the eye turns only some of the time. Strabismus is often hereditary, and is usually first noticed from birth to age 5. When children develop strabismus, their brain learns to turn off (or suppress) one eye to prevent double vi...
