A prospective study was undertaken to analyze the different causes of abnormal head postures on ocular bases. Eight basic mechanisms were found in a series of 188 patients. Incomitance accounted for 62.7% of the head postures and nystagmus for 20.2%. Important diagnostic criteria for evaluating patients with head postures are discussed.
