The importance of finding visual dysfunctions in children

K. Jokisch, W. Haase, T. Lifke

Background: The high number of amblyopia and visual dysfunctions in children at the age of 9 to 12 years shows the importance of an early screening to prevent amblyopia and visual dysfunktions..

Methods: We examinated following functions in children at the age of 9 to 12 years ( n= 623): the visual acuity with the Rodenstock R 5- tool, near vision with the C- Test ( single and row optotypes), cover- and cover-uncover-tests, binocular vision with the Titmustest, ocular motility, fixation, morphology.< /FONT>

Results: We found n= 78 ( 12.5 %) refractive anomalies, most there were hyperopia,n= 43 (6.9%). There were n= 23 ( 3.79%) myopia, n= 23 ( 3.7%) anisometropia, n= 12 ( 1.9%) astigmatism. In 216 patients ( 34.7%) we found heterophoria. There were n= 33 ( 5.3%) heterotropia, in n= 11 ( 33.3%) patients with heterotropia we found amblyopia. On the grounds of the definition of amblyopia as visual acuity < 0.7 C-test- single optotypes and < 0.63 C-Test row optotypes, we found n= 26 amblyopia ( 4.2%) from all examinated patients ( n= 623). Altogether we found n= 88 patients, which have to get a therapie of her visual dysfunction, this are 14.1% from 623 examinated patients.< /FONT>

Diskussion: Our results, that there are 5.3% heterotropia in children at the age of 9 to 12 years, are comparable with international visual screenings.
