摘要：

We determined how saccades were used in the experiments described in Epelboim, Steinman, Kowler, Edwards, Pizlo, Erkelens and Collewijn (1995) [Vision Research, 35, 3401-3422], where unrestrained subjects looked at or tapped nearby targets. We report: (i) the size of binocular saccades; (ii) how well saccade size matched in the two eyes; and (iii) saccadic vergence. A representative sample (3375 saccades) was measured: 83% were < 15 degrees, 53% were < 5 degrees. Only two were 'microsaccades'. Saccade sizes were very similar in the two eyes. These results imply that subjects prefer avoiding large saccades. They can do this simply by re-orienting the head appropriately. Subjects under-verged by 25-35% and preformed well. None experienced diplopia. (C) 2000 Elsevier Science Ltd. All rights reserved.
