title: [Binocular movements during pursuit and reading: eye tracking study].
abstract: Detailed analysis of fine, slow ocular movements has not been the object of recent studies. With this in mind, special hardware and a simple testing protocol were developed, along with software for recording and analysis. The study of these movements, using this hardware adapted to follow both eyes, allowed the inclusion of binocularity in the precise analysis of ocular pursuit and reading. Recording the eye movements of 166 children and adults permitted identification of the main features of oculomotor development from age five years. These movements were studied during calibrated pursuit and reading. The persistence of oculomotor abnormalities during development can help to define an array of "visual immaturity" or "visual inefficiency". The study of these anomalies during reading explains some learning difficulties.
