| Summary: |
Purpose: To determine factors, which have
influence on presence of strabismus among myopic patients with amblyopia.
Material and methods: Material covers 21 myopic patients with amblyopia,
aged 6 - 15. All children presented have a different amount of anisometropia, 12 of them
had strabismus. Authors, compared the group of patients with amblyopia and strabismus (12)
with the group of patients with pure anisometropic amblyopia (9), according to the
following criteria: age of presentation, best corrected visual acuity, mean refraction
error of amblyopic eye, mean amount of anisometropia, percentage of patients with central
fixation and binocular vision.
Results: Patients with strabismus presented oneself earlier than patients
without squint. Best corrected visual acuity was better in patients without strabismus.
Refraction error in both groups has similar value. Amount of anisometropia was slightly
smaller in the group with squint. Central fixation and binocular vision were better
preserved among patients without strabismus. Authors didn't find the following
correlations too: correlation between amount of anisometropia and amount of amblyopia in
both groups, correlation between amount of anisometropia and the amount of the deviation
of squinting eye, correlation between depth of amblyopia and the amount of deviation of
the squinting eye.
Conclusion: It seems, that primary factor leading to presence of
strabismus among patients with anisometropic myopia, is motor dysfunction of extraocular
muscles. |
