Monocular fixation and acuity in amblyopic and normal eyes.

We studied the relation between eccentricity of monocular fixation and the minimum angle of resolution invisually normal subjects and in both the amblyopic and dominant eyes of amblyopes. For the amblyopic and visually normal eyes, this relation was linear; resolution was poorer at the eccentrically fixating locus than at the corresponding region of the normal eye. The dominant eyes of the strabismic amblyopes had a nasal component of eccentric fixation that was less than that of the companion amblyopic eyes, but greater than the that found in the visually normal eyes. In terms of the eccentricity of monocular fixation, the domonant eyes of strabismic amblyopes were different from the normal eyes.
