What does intermittent strabismus mean?

What is Intermittent Strabismus? Just like strabismus (or tropia), intermittent (sometimes referred to as transient) strabismus is a condition in which the eyes are not properly aligned with each other. However, unlike constant strabismus, the condition is only evident intermittently (not all the time).

What is intermittent divergent squint?

Exotropia, or divergent squint, refers to an eye that turns or diverges outwards. Exotropia may occur from time to time (intermittent exotropia) or may be constant. You may only notice one particular eye drifting out, or it may be either eye that deviates, known as an alternating exotropia.

Does intermittent strabismus need surgery?

Surgery increases the risk of permanent vision loss, and/or lazy eye. The most common treatment options for intermittent strabismus include vision therapy, patching and eyeglasses with corrective lenses. The most successful form of treatment is in-office, supervised vision therapy with home reinforcement.

What causes intermittent exotropia?

Causes of exotropia Exotropia occurs when there’s an imbalance in eye muscles or when there’s a signaling issue between the brain and eye. Sometimes a health condition, like cataracts or stroke, can cause this to occur. The condition may also be inherited.

Can intermittent exotropia become permanent?

IS IT POSSIBLE TO OUTGROW INTERMITTENT EXOTROPIA? While it is possible for exotropia to become less frequent with age, most forms of exotropia do not resolve completely. However, some people may be able to adequately control the drifting with glasses or other non-surgical means.

Is lazy eye the same as strabismus?

Most people automatically use the term Lazy Eye when an eye crosses or turns outward. As stated above, an eye that moves on its own is a sign of Amblyopia or Lazy Eye, but Strabismus is the condition that one or both eyes turns inwards (esotropia) or out (exotropia).

What causes divergent strabismus?

Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma or infections. Risk factors include premature birth, cerebral palsy and a family history of the condition.

What age should strabismus be treated?

Infantile esotropia. According to the American Academy of Ophthalmology (AAO), up to 1 in 50 babies are born with this eye disorder. Cases that don’t resolve on their own by 4 months of age need medical treatment.

How is intermittent exotropia treated?

Current management options include watchful waiting,5 part-time occlusion,4, 6, 7, 8 over-minus spectacles,9, 10, 11, 12 fusion exercises,13 and strabismus surgery.

Can intermittent exotropia go away?

Exotropia—or an outward turning of the eyes—is a common type of strabismus accounting for up to 25 percent of all ocular misalignment in early childhood. Transient intermittent exotropia is sometimes seen in the first 4 – 6 weeks of life and, if mild, can resolve spontaneously by 6 – 8 weeks of age.

What is intermittent strabismus?

Intermittent strabismus is a combination of both of these types, where the person can achieve fusion, but occasionally or frequently falters to the point of a manifest deviation. Strabismus may also be classified based on time of onset, either congenital, acquired, or secondary to another pathological process.

What are strabismes Divergents intermittents (SDI)?

Les strabismes divergents intermittents (SDI), anciennement appelés exophories-tropies, sont une entité clinique décrite précisément par Duane dès 1896 [1].

Is strabisme compensable by intermittence?

En effet, les mécanismes de contrôles du strabisme sont très actifs : si l’on estime qu’il s’agit d’un strabisme divergent permanent compensé par intermittence, il serait plus juste de dire que le strabisme est complètement compensé par intermittence, et que quand cette compensation n’est pas suffisamment efficace elle n’est généralement pas nulle.

What are the divergences Verticales dissociées in strabism?

Les divergences verticales dissociées sont rares, témoignent de la précocité de l’apparition strabisme, s’associent alors à une stéréopsie moins bonne. Ces divergences verticales dissociées ont des angles moindres que celles rencontrées dans les ésotropies précoces [32]. Mesure de l’angle et classification du SDI Conditions de mesure
