What is Strabismus? by Dr. Jeffrey Cooper & Rachel Cooper (no relation). © 2001-2016 Does the Person Have Constant or Intermittent Strabismus? This is one of the most important findings the eye doctor makes! It is important for you as a parent or patient to understand the difference between constant and intermittent strabismus.
Duane's Syndrome (type I) It may be confused with a paralysis of the muscle which causes the eye to turn outwards (lateral rectus) resulting in an unnecessary neurological workup. Duane's is usually congenital and may be associated with other congenital disorders.
Exotropia -- a common type of strabismus -- is the outward deviation of an eye (eye turns away from the nose). When the eye turns outward only some of the time, it is called intermittent exotropia. Most exotropia is intermittent. In many cases, the eye turn might only be visible during stressful situations or when the person is tired, ill or anxious.
If the hypertropia is a decompensation of a congenital deviation, then treatment may consist of prism glasses and Vision Therapy. Our goal is fusion without prismatic glasses. However, often, treatment requires small amount of prism to hold the eyes in comfortable alignment.
What is infantile esotropia? Esotropia is an inward turning of one or both eyes. Infantile esotropia begins at birth or during the first year of life. Infantile esotropia is also called congenital esotropia [See figure 1]. Why does infantile esotropia occur? The cause of infantile esotropia is unknown.
