Abstract

Le dispositif comprend une lentille de contact scléral (1) pour placer et maintenir le dispositif sur l'oeil, ainsi qu'un système optique doté d'au moins une source lumineuse discrète, par exemple une fibre optique (9) ou une diode électroluminescente, et au moins un récepteur de lumière, par exemple une fibre optique (10) ou un photodétecteur, montés dans un support (6) sur ladite lentille de contact scléral (1). On peut utiliser le dispositif pour l'analyse spectrophotométrique de la rétine (31), ce qui permet son utilisation dans une grande diversité de techniques de diagnostic et de contrôle. Dans une autre réalisation (figs 5 et 6) on peut utiliser le dispositif pour la pupillométrie infrarouge. On prévoit d'autres dispositifs de détection disposés sur la lentille de contact (1).
