oCular Examination at Cell RESolution With Optical TransmissionTomography


Sponsor

Centre Hospitalier National d'Ophtalmologie des Quinze-Vingts

Enrollment

300 participants

Start Date

Nov 12, 2024

Study Type

INTERVENTIONAL

Conditions

Summary

Understanding the pathogenesis of eye diseases has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems, such as optical coherence tomography (OCT), are limited in terms of resolution, acquisition speed or access to certain eye functions. Our team has participated in the development of a new generation of imaging technology known as optical transmission tomography (OTT), which enables imaging of the anterior parts of the eye with high cellular resolution, a wide field of view and reduced examination delay.

Interventions

DEVICEOptical Transmission Tomography (OTT)

Multiple imaging sessions added by research using the systems described (OTT) will be carried out by two different operators at different positions during these sessions.

DEVICEOptical Coherence Tomography (OCT)

Multiple imaging sessions (OCT) already used in standard of care will be performed by two different operators at different positions during these sessions.

DEVICESpecular Microscopy (SM)

Multiple imaging sessions (SM) already used in standard of care will be performed by two different operators at different positions during these sessions.
