Abstract (en)
[origin: WO2021133402A1] Disclosed herein are methods and apparatus for making a determination about a cataract in an eye in ambient lighting conditions comprising: capturing, using an image capture device, one or more images of the eye of a subject, wherein each said image is captured using only ambient lighting conditions and wherein non-relevant reflections from the eye of the subject are managed while capturing the one or more images; determining, using a computing device in communication with the image capture device, one or more lens opacity qualities in each of the one or more images of the eye of the subject; and making a determination about a presence and/or severity of a cataract, optical distortion or opacity of the eye based on the one or more lens opacity qualities.
