简要总结
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.
详细描述
This XyCAM CRE Camera Study is a prospective longitudinal observational cohort imaging study. It is a non-randomized, non-masked, early feasibility study designed to collect retinal imaging data from healthy adults with normal retinal findings and from patients diagnosed with retinal and ocular diseases.
The study will consist of two phases: 1) screening and 2) testing. Patients presenting for routine ophthalmic standard of care evaluations will be screened for eligibility.
Eligible participants will complete four testing visits scheduled approximately 4 months apart (±2 months). At each testing visit, the Principal Investigator (PI) and designated study personnel will document participants' clinical status, obtain intraocular pressure (IOP) and blood pressure (BP) measurements, and acquire repeat XyCAM CRE retinal images. No additional follow-up will be required after completion of Visit 4 procedures.
The XyCAM CRE is an investigational, noninvasive optical imaging system manufactured by Vasoptic Medical, Inc. The device acquires rapid sequential digital retinal images while illuminating the retina with a low-power laser. Proprietary software algorithms analyze the image sequences to estimate retinal blood flow dynamics and generate additional quantitative vascular and structural measurements that may have diagnostic or disease-monitoring value.
The purpose of this study is to investigate the clinical utility of retinal and choroidal blood flow imaging and to evaluate the potential role of XyCAM CRE-derived measurements in the diagnosis and management of ocular disease. Up to 350 participants will be enrolled at Stuart Terry Eye Associates

入选标准
- •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.
排除标准
- •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.
