Title
(EN) METHOD AND DEVICE FOR MEASURING RETINAL STRAY LIGHT
(FR) PROCEDE ET DISPOSITIF DE MESURE DE LA LUMIERE PARASITE RETINIENNE
Abstract
(EN)
The present invention provides a method and device of measuring the retinal stray light in the eye of a subject, comprising presenting to the subject a flickering stray light from a stray light source; presenting to the subject compensation light so as to undercompensate said part of the flickering stray; presenting to the subject compensation light, the compensation light flickering with a modulation depth so as to eventually overcompensate the flickering light being imaged on the retina; and determining from the results of a sequence of comparisons using different parameter values between the resulting retinal light flickering as perceived by the subject for the undercompensated test area and the eventually overcompensated test area a stray light parameter.
(FR)
La présente invention se rapporte à un procédé et à un dispositif permettant de mesurer la lumière parasite rétinienne dans l'oeil d'un sujet, ledit procédé consistant à présenter audit sujet une lumière parasite tremblotante émise par une source de lumière parasite; à présenter au sujet une lumière de compensation afin de sous-compenser ladite partie de la lumière parasite tremblotante; à présenter au sujet une lumière de compensation, ladite lumière de compensation tremblotant avec une profondeur de modulation permettant de sur-compenser éventuellement la lumière tremblotante formant une image sur la rétine; et à déterminer un paramètre associé à la lumière parasite à partir des résultats d'une séquence de comparaisons effectuées au moyen de valeurs de paramètres différentes entre la lumière rétinienne résultante tremblotant de la manière perçue par le sujet pour la zone d'essai sous-compensée et éventuellement la zone d'essai sur-compensée.
