Title
(EN) PROCESS FOR ADJUSTING TREATMENT PARAMETERS FOR RETINA PHOTOTHERAPY BASED ON RPE MELANIN LEVELS
(FR) PROCÉDÉ D'AJUSTEMENT DE PARAMÈTRES DE TRAITEMENT POUR LA PHOTOTHÉRAPIE RÉTINIENNE SUR LA BASE DE TAUX DE MÉLANINE DANS L'EPR
Abstract
(EN)
A process for safely providing retinal phototherapy includes generating first and second light beams of a different wavelength. The first and second light beams are applied to a retinal pigment epithelium (RPE) and choroid of an eye The amount of light reflected from the eye from the first light beam and the second light beam is measured, such as using a reflectometer. A level or concentration of the melanin within the eye is calculated using the measured amount of light reflected from the eye from the first and second light beams. When the content or density of melanin in the RPE exceeds a predetermined amount, one or more treatment parameters of the retinal phototherapy is adjusted.
(FR)
L'invention concerne un procédé pour fournir en toute sécurité une photothérapie rétinienne, ledit procédé comprenant la génération d'un premier et d'un second faisceau lumineux d'une longueur d'onde différente. Le premier et le second faisceau lumineux sont appliqués à un épithélium pigmentaire rétinien (EPR) et à la choroïde d'un oeil, la quantité de lumière réfléchie par l'oeil, provenant du premier faisceau lumineux et du second faisceau lumineux, étant mesurée, par exemple à l'aide d'un réflectomètre. Un taux ou une concentration de mélanine dans l’œil est calculé au moyen de la quantité mesurée de lumière réfléchie par l'œil, provenant du premier et du second faisceau lumineux. Lorsque la teneur en mélanine ou la densité de mélanine dans l'EPR dépasse une quantité prédéterminée, un ou plusieurs paramètres de traitement de la photothérapie rétinienne sont ajustés.
