ABSTRACT

Objective: To determine the usefulness of stereo tests: Lang II, Frisby, Titmus and Random Dot E; to detect amblyopia and strabismus in children.
Materials and methods: A total of 1048 children aged 3 to 5 years (preschool children) and 6 to 8 years (school children) were examined in a field study in Mexico City and Ciudad Victoria, Tamaulipas, Mexico. The examination included stereo test, visual acuity, cover testing, refraction (skiascopy) and inspection of the posterior pole.
Results: In the preschool group the higher sensitivity for amblyopia was 61.53% with Random Dot E and for strabismus was 75% with Lang II, Titmus and Random Dot E. In the school group the higher sensitivity for amblyopia was 78.57% with Random Dot E and for strabismus was 100% with Random Dot E.
Conclusions: Stereo test Frisby in preschool and school children rule out the presence of strabismus and amblyopia in healthy children. Stereo test Random Dot E confirms the presence of strabismus in school children. Stereo test Lang II and Titmus are useful to establish the level of stereopsis.
