Summary

Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye.

The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many microstructures of the eye: photoreceptors, vessels, nerve bundles in the retina, cells and nerves in the cornea.

The use of a high-speed acquisition imaging system makes it possible to detect functional measurements such as the speed of blood flow. The combination of data from multiple imaging systems to obtain multimodal information is of great importance for improving the understanding of structural changes in the eye during a disease.

The purpose of this project is to observe structures that are not detectable with routinely used systems.

Description

The goal of the project is the capture and analysis of images with the IMA-MODE systems, in order to evaluate the performance of these systems compared to the existing clinical imaging devices used at the National Hospital of Ophthalmology.

This project should identify the best techniques to image the eye, and select the most promising techniques to evolve towards a possible development of a medical device.
