Design and implementation of a testing and validation optical phantom device for ocular oximetry
Early detection of eye diseases, such as glaucoma and diabetic retinopathy, can help prevent blindness. These diseases are related to the supply of oxygen to the retina. Early diagnosis is therefore possible using retinal oximetry based on spectroscopic techniques. Currently, retinal oximetry can be performed with a device based on the concept of retinographs, common in optometry. However, these devices are bulky and heavy. The design of a handheld retinal oximetry device is necessary in order to meet the requirements of use in the context of medical emergencies.
We are currently working on the design and development of a portable retinal oximetry device in collaboration with a company. This prototype aims at a clinical implementation for the diagnosis of various degenerative diseases. This device must be tested in the laboratory to guarantee its performance. A key component of device validation is the creation of an optical phantom that mimics the characteristics of the eye. This work presents several challenges, but its completion will greatly facilitate testing of the device, as well as research and development in the field of ocular oximetery in the future.

Optical Engineering research lab
Led by Prof. Simon Thibault, PhD, Ing., the Optical Engineering research lab (LRIO in french) at Université Laval is the only Canadian laboratory offering post-graduate training in optical design. Our goal is to develop solutions in different fields of study within modern optics, working on both theoretical and practical applications for astronomy, space exploration, medical application, security and surveillance, teledetection, machine vision, industrial inspection, military systems and lighting.
Zilia is developing a groundbreaking technology bound to redefine the way we prevent, diagnose, and treat various ocular, neurological, and systemic conditions. The company has been collaborating with LRIO for several years.
