METHOD AND DEVICE FOR MONITORING RETINOPATHY

摘要

There is provided a method of monitoring retinopathy in a subject. The method involves measuring autofluorescence of a retina in response to high intensity blue light and infra-red reflectance of the anterior region of an eye in response to high intensity infra-red light of the subject over a total time period to obtain an autofluorescence intensity profile and an infra-red reflectance intensity profile. The autofluorescence intensity profile and infra-red reflectance intensity profile are processed to obtain a pupillary light reflex measurement that is used to assess the retinopathy status of the retina.

1. A method of monitoring retinopathy in a subject, the method comprising:
directing pulses of high intensity blue light at the retina of an eye of the subject subject over a total time period; directing high intensity infra-red light at the anterior region of the eye of the subject over the total time period; measuring autofluorescence of the retina in response to the blue light to obtain an autofluorescence intensity profile; measuring infra-red reflectance of the anterior region of the eye in response to the infra-red light to obtain an infra-red reflectance intensity profile; processing the autofluorescence intensity profile and the infra-red reflectance profile to obtain a pupillary light reflex measurement in order to assess the retinopathy status of the retina.
