[Electro-oculographic study of reading in hemianopic patients]. / Etude électro-oculographique de la lecture chez les hémianopsiques.

Recordings of ocular movements during reading in hemianopic patients showed an increase in global reading time related mainly to the increase in number of movements of progression and regression in left hemianopsia and to the time to return to the line in right hemianopsia. Comparison of these changes with those noted in the same patients during recordings of elementary ocular movements and reading simulation suggests that they are not only of a linguistic and/or cognitive type but that they may also be related to altered sensorial data such as size of words or place of spaces between words.
