A voluntary control, intended to obtain an increase in retinal reflection, is carried out using an auditory biofeedback technique based on the measurement of retinal reflection, for the purpose of achieving an improvement in visual perception in its principal functions; the method comprises the following phases: periodic measurement of the retinal reflection and of its variations, independently of factors concerning ocular optics; production of a tone representative of such measurements, which informs the patient as to the condition and as to the variations of his own retinal reflection; instruction on voluntarily increasing the retinal reflection by means of the voluntary control of the biofeedback tone. The apparatus comprises a source (1) of infrared radiation which is transmitted to a subject's eye (0). The radiation which reflects back from the retina is reflected by semireflecting mirror (12) to sensor (18), whose signals are processed by system B and converted into an audible tone emitted by speaker (34). |
