Collecting Data on Retinal Blood Blood Flow and Blood Vessel Shape/Appearance Using an Investigational Device, XyCAM CRE, and to Then Compare Those Images With Images Collected From a Patient's Routine Clinical Examination.

Plain-language summary
The primary objective of the XyCAM CRE Camera Study is to evaluate retinal blood flow, choroidal blood flow, and retinal structural features and their association with the progression and characterization of retinal diseases using the XyCAM CRE Camera. The XyCAM CRE is an investigational, noninvasive optical imaging instrument manufactured by Vasoptic Medical, Inc.
XyCAM CRE imaging data will be collected and compared with established retinal imaging modalities currently used in ophthalmic clinical practice, including Color Fundus Photography (CFP), Optical Coherence Tomography (OCT), Optical Coherence Tomography Angiography (OCTA), and Fluorescein Angiography (FA). Imaging data obtained from XyCAM CRE and reference modalities will be assessed to investigate correlations, agreement, and differences between measurements in order to evaluate the potential of XyCAM CRE to provide complementary diagnostic and disease management information in retinal disease.
Secondary objectives of the study include:
Comparing image quality and image-derived information obtained from XyCAM CRE with other clinical reference imaging modalities across different operators and a diverse study population representative of the general population; Investigating the relationship between XyCAM CRE imaging data and established clinical indicators of glaucoma, macular degeneration, hypertensive retinopathy, diabetic retinopathy, inherited retinal disease, and retinal vascular disease.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* The Subject present to the ophthalmology/optometry clinic for eye examination. A signed/dated consent form has been obtained from a Subject who is capable of giving informed consent and compliant with the restrictions and requirements if the protocol.
The Subject is 21 years old with binocular vision.
Exclusion Criteria:
* The Subject has significant media opacity (eg: a significant corneal scar) The Subject's medical history or health status suggests that the Subject may have an adverse reaction to administration of tropicamide or fluorescein dye.
The Subject has more than 15 dioptors of refractive error. The Subject is less that 21 years of age. The Subject is unable to follow instructions or otherwise unable to complete the study procedures.
The Subject has medical conditions such as nystagmus that will likely prevent the Subject from being able to hold their gaze steady during imaging, reducing the likelihood that high quality data can be acquired from the Subject.
The Subject is pregnant.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Correlation of XyCAM CRE retinal blood flow measurements with reference retinal imaging modalities in retinal disease
Timeframe: From enrollment through completion of Visit 4 (approximately 12-18 months). Participants will complete four testing visits scheduled approximately 4 months apart (±2 months).
