System and method for retinopathy detection

A device providing an indication of eye disease in a patient comprises a light emitter; an optical assembly arranged so that light emitted from the light emitter reaches an eye of the patient; a camera arranged to image the eye of the patient; and a controller. The controller measures the eye's pupil area using images received from the camera and adjusts the luminance of the light emitted from the light emitter as a non-constant function of the eye's pupil area so as to create a plurality of stimulus intervals. At least two of the stimulus intervals differ in their average retinal illuminance. The controller analyzes the pupil measurements and/or an electrical response in at least two of the stimulus intervals to provide an indication of eye disease based. In some embodiments, the patient's age is also used in the analysis. Methods of using said device are also contemplated. 患者眼疾提示装置，包括光发射体；光学组件，其设置成使从光发射体射出的光到达患者眼睛；照相机，其设置成对患者眼睛进行成像；和控制器。控制器利用接收自照相机的图像测量眼睛瞳孔面积，将从光发射体射出的光的照度调节成眼睛瞳孔面积的非常量函数，以创建多个刺激间隔。至少两个刺激间隔的
