In order to evaluate the ocular autonomic dysfunction in diabetics, pupil cycle time(PCT) was assessed in 201diabetics and 33controls. PCT was significantly different between the diabetics and controls and prolonged in diabetics in regard to the severity of retinopathy(p<0.05). PCT was significantly prolonged in diabetics in regard to the diabetic peripheral neuropathy and nephropathy(p<0.05). PCT was significantly different among the diabetic groups in regard to the duration of diabetes(p<0.05). Sustainde PCT was unmeasurable in 56.7% of diabetics and in 72.3% of proliferative diabetic retinopathy compared with 28.8% of controls(p<0.05). Ocular autonomic dysfunction in diabetics correlated closely with the severity of the diabetic retinopathy, diabetic petiphetal neuropathy and nephropathy, diabetic duration.
