The apparatus comprises means for producing a beam of optical radiation over all of a patient's prima and modulation means to modulate the radiation. The apparatus may comprise a pair of earpieces 10 joined by a band 12 to fit on a patient's head. Each earpiece 10 may be provided with an inwardly directed light source 14 comprising a plurality of light emitting diodes (LEDs) which may be battery powered or powered from an electrical mains supply by way of a combined plug and transformer 16, a cable 18 and a control box 20. The control box 20 may comprises a switch 22 whereby the dc power to the light sources 14 is turned on to irradiate the patient's outer ears with radiation of a selected wavelength and may comprise a rotary control 24 for adjusting the length of time it is on. |
