In our study, exotropia was more common than esotropia
. This finding was similar to others where exotropia cases were greater than esotropia
.78 In a study done among 322 cases of strabismus, 262 cases (81.4%)were exotropia and 60 cases (18.6%) were esotropia
.9 In Cameroon, exotropia was found in 75% cases and esotropia
in 25% of cases.10 Matsuo found that the prevalence of strabismus was 1.28% in which exotropia was the most prevalent than any other type of strabismus.11 In addition, in a population at Iran, exotropia accounted 1.3% whereas esotropia
accounted 0.59% only.
All the cases were either diagnosed as esotropia
without optical correction or diagnosed as esotropia
, esophoria, microtropia, or eccentric fixation; they all received proper optical corrections.
is described as convergent deviation of the eyes related with activation of accommodation reflex.
* If there is NO movement of the uncovered eye when you remove the cover and the uncovered eye remains fixated then an alternating exotropia or esotropia
is present (the child is able to fixate with both eyes).
Patients with esotropia
are more likely to develop amblyopia (4).
Se puede examinar el reflejo corneal a la luz y realizar la prueba de oclusion-desoclusion (cover-uncover test) para diferenciar el estrabismo del pseudoestrabismo, en el que encontramos una percepcion de desviacion medial o esotropia
causada por un pliegue prominente, medial, del canto y un puente nasal plano [1, 2].
They found that kids with eyes that diverged (exotropia) were three times more likely to develop a psychiatric disorder than were the control subjects, while those with inward deviating eyes (esotropia
) showed no increase in the incidence of mental illnesses.
Pivnick's 5-year-old daughter Lilla required eye surgery to correct her esotropia
12 years ago, there was no doubt in her mind that she wanted her close friend and colleague Dr.
An inward deviation of the eyeball caused by an unequal pulling of the muscles that move the eyes is called esotropia
. This is one type of eye muscle disorder, or strabismus.
Carson has a small head, absent frenulum (a fold of mucous membrane under the tongue, which limits the movement of the tongue, aiding speech and eating), esotropia
of the eyes (cross-eye; internal or convergent strabismus), and has worn glasses since he was 6- months old.
