Haase” is based on the assumption that a minute deviation from the orthovergence position (fixation disparity)-indicates a difficulty to overcome a larger “ vergence angle of rest” . Objective recordings have,however,revealed that the subjective tests applied in the “ Measuring and Correcting Methodology after H.-J. Haase” can mislead to the assumption of a fixation disparity,although both eyes are aligned exactly to the fixation point. Question: How do patients with an inconspicuosly small,yet objectively verified strabismus react to the “ Measuring and Correcting Methodology by H.-J. Haase” ? Methods: Eight patients with amicroesotropia between 0.5 and 3° were subjected to the “ Measuring and Correcting Methodology after H.-J. Haase” . Results: In all 8 patients,the prisms determined with the Cross-,Pointer-and Rectangle Tests increased the angle of squint,without reaching a full correction: the original angle prevailed. In the Stereobalance Test,prisms did not reduce the 100% preponderance of the non-squinting eye. The stereoscopic threshold was between 36 and 1170 arcsec in 7 out of the 8 subjects,and above 4000 arcsec in 1 subject. Conclusions: (1) In all 8 patients,prisms determined with the “ Measuring and Correcting Methodology by H.-J. Haase” increased the angle of strabismus,without reaching bifoveal vision. This uniform result suggests that primary microesotropia cannot be corrected with the “ Measuring and Correcting Methodology after H.-J. Haase” (2) A lacking contribution of the strabismic eye to the recognition of a lateral off-set between stereo objects,as determined with the Stereobalance Test,does not imply a lack of binocular stereopsis.展开更多
