Abstract: Method, system and computer program for measuring light diffusion in the eyeball or in the ocular region. The method comprises: projecting a punctiform light beam onto the retina; correcting low-order ocular aberrations of the eye; capturing and recording an image of the retinal plane formed after reflection of the punctiform light beam on the retina and a double passage through the ocular media of the eye; and at the same time as capturing the image of the retinal plane, performing a high- and low-order ocular aberration measurement in the plane of the pupil and performing a light diffusion measurement, combining ocular aberration measurement information with information on the image of the retinal plane. The system and the computer program are adapted for implementing the method.

Abstract: The invention relates to a method and system for the objective measurement of ocular accommodation. A double-pass ophthalmoscopic system is used which incorporates a periscope allowing the patient to binocularly see real objects in an open field and images of the retinal plane to be recorded on a CCD camera. The method includes obtaining, for different values of accommodation stimulation, a set of retinal images corresponding to different focal values in the retina, obtaining the different focal positions in the retina by moving the two lenses incorporated in the ophthalmoscopic system. The image with the best optical quality is obtained for each set of images and by associating the selected image with the known value of the accommodation stimulation it is possible to objectively measure the accommodation.
