Strabismus (also known as crossed-eyes) is commonly mistaken for the condition known as “lazy eye”. However, they are two distinct or different conditions. Strabismus is a crossed or turned eye. A person with Strabismus under normal conditions cannot align both eyes simultaneously. One or both of the eyes may turn out, in, up, or down. Some of the confusion between the two conditions is that Strabismus can often times cause the condition known has lazy eye. An eye turn may be constant or intermittent. Constant Strabismus and Intermittent Strabismus are both conditions which require appropriate treatment and attention. AlternatingStrabismus or Intermittent Strabismus is rarely found as the cause of lazy eye.
Strabismus is commonly referred to by any of the following names:
- Crossed Eye
- Lazy Eye
- Wandering Eye
Strabismus is a disorder of the eye involving a lack of coordination between the muscles of the eye. Essentially, the eyes do not point in the same direction. This prevents bringing the gaze of each to the same point in space, preventing proper binocular vision, which in turn adversely affects depth perception.
Types of Strabismus include:
- hypertropia , or one eye turning upward
- esotropia , or one eye turning inward
- exotropia , or one eye turning outward
Strabismus can be treated as follows:
Treatment selection will depending on the underlying reason for the misalignment. Early treatment of Strabismus in infancy can reduce the chance of development of amblyopia and depth perception problems. Eyes that remain misaligned can still develop visual problems. Prism lenses can also be used to provide some comfort for sufferers and to prevent double vision from occurring. However, prisms and lenses do not cure the condition.
