What this Trial Is About
Many retinal pathologies are of vascular origin. In order to better understand their pathophysiology and make an accurate diagnosis, it is essential to visualise and quantify blood flow. The holographic Doppler laser (LDH) is a new medical device currently being developed by physics researchers at the Institut Langevin. The 1st prototype of this device is currently being used as part of research involving humans with minimal risks and constraints at the Hôpital National de la Vision des Quinze-Vingts (NCT04129021). In order to better visualise, understand and quantify the vascular anomalies suspected in the fundus of patients undergoing ophthalmology treatment , we would like to acquire images/videos with a 2nd LDH prototype, within the ophthalmology clinical investigation platform at the Hôpital Fondation Adolphe de Rothschild.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Age 18 years or older
- Provided informed consent to participate in the study
- Affiliated with or beneficiary of social insurance
- No known eye disease other than refractive disorder (for participants without ocular pathology)
- Undergoing ophthalmology consultation for optic nerve pathology in at least one eye (e.g., glaucoma, optic neuritis, hereditary optic nerve diseases)
- Undergoing ophthalmology consultation for retinal and/or choroidal pathology in at least one eye (e.g., diabetic retinopathy, age-related macular degeneration)
- Undergoing ophthalmology consultation for retinal vascular pathology in at least one eye (e.g., central retinal artery occlusion, central retinal vein occlusion, ocular ischemia syndrome)
You will not qualify if you...
- Unable to maintain a stable sitting position
- Contraindications to holographic Doppler laser including:
- Implanted medical electronic device (e.g., pacemaker)
- History of photosensitivity
- Received photodynamic therapy within the last 3 months
- Viral conjunctivitis or other infectious disease
- Skin lesions on the neck or forehead preventing chin strap contact
- High risk of damage from optical radiation (e.g., aphakic patients or patients with reduced light sensitivity due to disease of the back of the eye)
