Is there a systematic location for the pseudo-fovea in patients with central scotoma?

Studied the retinal location of preferential fixations of 24 patients (aged 24-98 yrs) with central scotoma when reading digits projected onto their retina with a scanning laser ophthalmoscope. In the majority of cases the fixation was located on the left part, or the inferior part, of the visual field relative to the central scotoma. The fact that the inferior visual field was used is congruent with the notion that the lower visual field is important for locomotion. However, the preferential use of the left field appears contradictory with data showing superiority of visual faculties in the right visual field. This result may be explained in relation to the need for left-to-right readers to monitor where their eyes have landed relative to the word previously fixated on the left.
