New pupillometric method for the screening of visual pathologies

A new pupillometric method for the screening of visual pathologies, using the pupillary response for an automatic, objective and rapid examination of the visual field

Market Challenges
Prevalence and incidence of pathologies impacting vision are increasing constantly. Early detection of these diseases would improve patient management and enable a reduction of related health costs. The diagnosis of retina pathologies involves a visual field test to establish which areas of the retina are affected, or not, by the disease. However, this test has some important limitations:
• It can take more than 10 minutes and be tiring and stressful
• Il addition, it is a subjective task, requiring a sustained attention and depending on the understanding of the task and the choice (often implicit) of a response criteria. Thus, this examination is unsuitable for certain types of patients, such as infants or people suffering from dementia
• Finally, the results often depend on the practitioner’s experience

Innovative solution
The invention is a new pupillometric method for the screening of visual pathologies, using the pupillary response for an automatic, objective and rapid examination of the visual field.

Development status
A first prototype has been produced, and tests have been conducted on 45 patients (RP, Stargadt, Leber) and 15 healthy subjects.
