| Summary: |
Purpose: To examine
the amount of defect of stereopsis in experimentally
induced anisometropia of various value and type.
Material and methods: 20 healthy adults without
significant refraction error or anisometropia and with
full stereopsis were examined. They all undergone Titmus
stereotest (circles) after they had experimentally
induced anisometropia with the use of trial lenses. Mean
values of stereopsis in arc sec. were calculated for
each value of anisometropia.
Results: The largest defect of stereopsis was
noted in spherical hypermetropia. In all kinds of
refraction error the critical value for almost complete
loss of stereopsis was 3D plus. Generally, the same
values of anisometropia in sphere result in slightly
more severe loss of stereopsis than in cylinder. |
