A preliminary report of acuity and contour interactions across the amblyope's visual field

Acuity and contour interactions were assessed across the visual field of representative strabismic amblyopes. Acuity profiles display large variations between amblyopes who exhibit the same degree of eccentric fixation; however, in no case was foveal acuity significantly better than that found eccen...

Summary:Acuity and contour interactions were assessed across the visual field of representative strabismic amblyopes. Acuity profiles display large variations between amblyopes who exhibit the same degree of eccentric fixation; however, in no case was foveal acuity significantly better than that found eccentrically. The acuity abnormality for most amblyopes is visual field locus dependent. Contour interactions are abnormal in both form and magnitude for some amblyopes. This abnormality does not depend upon the acuity deficit, is field locus dependent and cannot be easily accounted for by optical, oculomotor or eccentric fixation factors.
