ClinConnect Summary

This clinical trial is focused on using a new device called the holographic Doppler laser to take detailed images of the blood vessels in the eye. By studying these images, researchers hope to better understand various eye conditions that are related to blood flow problems, which can help in making accurate diagnoses. The trial is currently recruiting participants who are 18 years or older, and it includes those with specific eye conditions, such as glaucoma or diabetic retinopathy, as well as individuals without any known eye problems.

Participants in this study will have the opportunity to contribute to important research while experiencing minimal risks. They will need to provide informed consent, meaning they understand the study and agree to take part. Those who participate will undergo eye examinations using the new device to capture images and videos of their eye's blood vessels. It’s important to note that there are certain criteria that would exclude someone from participating, such as having specific medical devices or conditions that could be affected by the imaging process. This trial aims to improve our understanding of eye health and could lead to better treatments in the future.
