What this Trial Is About

Researchers are evaluating advanced ophthalmic imaging techniques to better understand eye conditions that can lead to blindness. This study focuses on using high-resolution and high-speed imaging systems to capture detailed images of eye microstructures like photoreceptors, blood vessels, and nerve bundles. The goal is to observe eye structures that are not visible with standard clinical imaging technologies and improve knowledge of structural changes during eye diseases. The study involves two main imaging approaches: high-resolution retinal imaging through adaptive optics with full-field optical coherence tomography, and retinal imaging using laser Doppler holography. Participants will undergo these imaging procedures, which require placing the forehead and chin on supports while fixing on a test pattern. Each imaging session lasts less than half an hour, with possible repeated acquisitions to cover the desired eye area. The imaging protocols may be adjusted based on the participant’s eye condition and the specific system used. During the study, participants will have their eye structures visualized and the reproducibility of imaging data measured over time, up to five years. The researchers will compare these advanced imaging results with those from routine clinical systems. The study includes both patients with various eye pathologies and healthy volunteers. Participants will be monitored for safety, and the study collects detailed imaging data to evaluate the effectiveness of these new imaging technologies.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Implementation

Duration - Single session or multiple sessions as determined by the study protocol

Participants undergo high-resolution retinal imaging using adaptive optics, full-field optical coherence tomography, and holographic systems. The imaging sessions involve positioning the head with support and focusing on test patterns, with each exam lasting less than half an hour and including frequent breaks. The exact imaging protocol varies based on individual pathology and system used.

1 or more visits depending on imaging requirements

Long-term Monitoring

Duration - Up to 5 years from date of inclusion

Participants are monitored to assess the reproducibility of imaging data and the visualization of ocular structures over time compared to routine systems.

Follow-up visits as scheduled over the monitoring period
