Abstract[English]
In certain embodiments, an ophthalmic diagnostics system includes a polarization sensitive optical coherence tomography (PS-OCT) device. The system also includes a memory having executable instructions. The system also includes a processor in communication with the memory and configured to execute the instructions to cause the PS-OCT device to emit polarized light to a measurement location on eye tissue of a patient and generate PS-OCT data based on the polarized light. The processor is further configured to execute the instructions to determine birefringent information for the measurement location based on the PS-OCT data and to determine biomechanics information for the measurement location based on the PS-OCT data. The processor is further configured to execute the instructions to determine a correlation between at least a portion of the biomechanics information and at least a portion of the birefringent information.[French]
Dans certains modes de réalisation, un système de diagnostic ophtalmique comprend un dispositif de tomographie par cohérence optique sensible à la polarisation (TCO-PS). Le système comprend également une mémoire comportant des instructions exécutables. Le système comprend également un processeur en communication avec la mémoire et configuré pour exécuter les instructions pour amener le dispositif TCO-PS à émettre une lumière polarisée vers un emplacement de mesure sur un tissu oculaire d'un patient et générer des données TCO-PS sur la base de la lumière polarisée. Le processeur est en outre configuré pour exécuter les instructions pour déterminer des informations de biréfringence pour l'emplacement de mesure sur la base des données TCO-PS et pour déterminer des informations de biomécanique pour l'emplacement de mesure sur la base des données TCO-PS. Le processeur est en outre configuré pour exécuter les instructions pour déterminer une corrélation entre au moins une partie des informations de biomécanique et au moins une partie des informations de biréfringence.
