Forms of Strabismus

In some cases, vertical and horizontal misalignments occur together, and there may even be a rotational component. The degree and direction of the strabismus can also change depending on where the eyes are looking. And, as with most things in medicine, there are always a few exceptions to the rule.

Why It’s Never Just One Eye

Skilled strabismus specialists understand how to assess alignment and recommend appropriate treatment options for the eyes. The emphasis on “eyes”—plural—is intentional. While it may look like only one eye is out of place, strabismus actually affects both. Misalignment is always related to the position of one eye compared to the other.

When Does Strabismus Appear?

Strabismus may be noticeable all the time (tropia), only under certain conditions, such as fatigue, illness, or specific testing (phoria), or somewhere in between (intermittent tropia). For example, a person might have an esophoria, where the eyes turn inward toward the nose only when tired; an intermittent esotropia, where the eyes occasionally turn inward on their own; or an esotropia, where the inward turn is constant.

Why Do We Need Properly Aligned Eyes?

When the eyes are properly aligned (“straight”), both eyes are looking at the same object simultaneously. Because our two eyes are slightly separated naturally, two separate (and slightly different) images are perceived and sent to the brain. Within the brain, these two slightly separate images are fused into a single three-dimensional (3-D) perception. Depth perception is only possible when both eyes point in the same direction at the same time.

What Happens When the Eyes Are Misaligned?

When someone has strabismus, their eyes are pointing in different directions at the same time, so their brain is presented with two very different images simultaneously. Our brain cannot fuse very different images into one, so depth perception (3-D vision) is not possible when strabismus is present.

For Young Children

When a young child has a very frequent or constant strabismus, their brain ignores one of the images, and normal depth perception cannot develop or is lost. Certain forms of strabismus (usually esotropias) can cause the brain to ignore an eye altogether, and vision will be lost (amblyopia). 

For Older Children and Adults

Visually mature children (older than eight or so) and adults who develop strabismus cannot just ignore the second image, so they often develop double vision. Fortunately, nearly all forms of strabismus can be treated and made better.

I love how he treated the kids like it's their appointment and not the parents’.

Understanding Abnormal Head Position (AHP)

Certain eye movement problems will cause people to position their head in an abnormal manner. AHP typically appears as:

  • A face turn to the right or left
  • A head tilt towards the shoulder
  • Chin up or down
  • Combinations of turns, tilts, and chin-up/down positions

It is important to determine whether an AHP is caused by an abnormal eye movement. For very young children, uncorrected AHPs can cause changes in facial and neck bone development.   In addition, if physical therapy is attempted for an undiagnosed AHP, this can lead to vision loss (amblyopia).  As for older children and adults, AHPs can cause neck pain and/or self-esteem issues.

Eye Conditions Linked to an Abnormal Head Position (AHP)

There are three generally accepted ophthalmic causes for AHP:

Strabismus (Misaligned Eyes)

Some forms of strabismus will vary depending on where the person is looking.  By assuming an abnormal head position, these folks have learned how to make their eyes straight.  They do this because it reduces/eliminates double vision and may even permit good 3-D vision.

Nystagmus (Shaky/Dancing Eyes)

Many forms of nystagmus are minimized when looking toward a particular direction.  By assuming an abnormal head position, people with nystagmus are able to reduce their nystagmus and see better.   

Ptosis (Droopy Eyelid)

When the eyelid blocks the pupil, vision is not possible, so these folks may lift their chin to “look under” the drooping lid and see things in 3-D.

What’s Behind Your Child’s Abnormal Head Position (AHP)?

Dr. Lichtenstein wants to know why your child’s head is positioned abnormally. To find out, he’ll perform a full eye exam and specialized tests to clarify what’s going on. He may also place a patch on one eye, noting if the AHP improves. Together, these findings help us determine whether a specific eye condition is behind an AHP.
