Abstract
A patient with presenile dementia had instability of ocular fixation caused by small rapid horizontal eye movements (square-wave jerks). High resolution recordings of these eye movements were characteristic of microsaccades, which ordinarily occur during fixation, in all respects except amplitude. In addition, the patient showed a complete absence of normal microsaccades. We suggest that microsaccades have become altered in our patient to form a clinical disorder of fixation.This publication has 2 references indexed in Scilit:
