What this trial studies

This clinical trial investigates the effectiveness of the XyCAM RI and XyCAM FC, FDA-cleared retinal blood flow imaging instruments, in managing glaucoma. The study aims to determine if blood flow measurements can differentiate between early-stage glaucoma and matched controls, while also validating the simultaneous capture of stereo fundus photography and ocular blood flow monitoring. Participants will undergo a series of imaging tests, including blood flow imaging and standard clinical assessments, to gather comprehensive data on their ocular health. The trial will involve both healthy controls and patients diagnosed with moderate to severe glaucoma.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 and older with binocular vision, either healthy controls or those recommended for glaucoma assessment or diagnosed with moderate to severe glaucoma.

Not a fit: Patients with significant media opacity, previous ocular surgeries (other than uncomplicated cataract extraction), or other ocular diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of glaucoma assessments and improve patient management strategies.

How similar studies have performed: Other studies utilizing advanced imaging techniques for glaucoma assessment have shown promise, indicating potential success for this novel approach.
