%X For investigating the OKN in subjects with normal and abnormal binocular vision, the OKN eye movements evoked by monocular stimulus were recorded and analysed for emmetropes and different types of amblyopes. The experimental data showed that: (i) Nasalward and temporalward OKNs are symmetric both in emmetropes and ametropic amblyopes; (ii) Esotropic and anisometropic amblyopesdemonstrate asymmetric OKN; (iii) The gains of OKN in all amblyopes are lower than in emmetropes. Therefore to distinguish abnormal binocular vision patients from emmetropes and to categorize the amblyopes can be achieved by OKN test, especially for infant amblyopes. The results also provide an evidence for supporting the hypothesis that the OKN asymmetry is caused by maldevelopment of binocular cells in visual cortex.
