A method of monitoring a subject for medical conditions includes causing light to impinge on at least one eye of the subject, directing reflected light from such light beam to photosensors, converting the received reflected light to corresponding electrical signals (202) which are delivered to a processor. Processing the signals by effecting a comparison between stored information (210) regarding the medical condition and the data provided by the monitoring (202) to determine if an undesired medical condition exists and, if so, communicating such result (214). The cycle is repeated at predetermined intervals which may be short or prolonged. The stored information may be information relating to the specific subject or general information regarding normal and abnormal conditions of the eye representative of toxicity. The eyes may be monitored sequentially or simultaneously. Related apparatus is provided.

L'invention concerne un procédé de contrôle d'un sujet, visant à déceler des états pathologiques chez ce dernier. Ledit procédé consiste à : projeter de la lumière sur au moins un oeil du sujet ; diriger la lumière réfléchie de ce faisceau de lumière vers des capteurs optiques ; transformer la lumière réfléchie reçue en des signaux électriques correspondants, lesquels sont acheminés vers un processeur ; traiter les signaux, en comparant les informations stockées concernant l'état pathologique aux données émises lors du contrôle, afin de déterminer la présence d'un état pathologique non souhaité, et, dans ce cas, communiquer ce résultat. Le cycle est répété à des intervalles prédéterminés, qui peuvent être courts ou prolongés. Les informations stockées peuvent être des informations relatives au sujet en particulier, ou des informations générales concernant les états normaux et anormaux de l'oeil et donnant des indications sur la toxicité. Les yeux peuvent être contrôlés successivement ou simultanément. L'invention concerne également un appareil permettant d'effectuer un tel contrôle.
