Vessel Imaging Study (VIS)

This study is now closed to enrollment

Why we are doing this study:
This study will be testing a new feature of an existing imaging device (Spectralis OCT) to noninvasively assess the flow of blood through the blood vessels at the back of the eye.

Who can be in the study?
You may be eligible to participate if you are 22 years of age or over and have:

  • A retinal vascular disease,
  • Or healthy eyes (no eye diseases and good vision).

Further screening questions will be asked prior to scheduling an appointment.

What the study involves:
Participants will be assessed using procedures typical of a comprehensive eye examination (including dilation) and aim to verify that the eyes meet the requirements to be grouped in one of the categories being studied. If the doctor deems it necessary or if you are randomly assigned to, your eyes may be dilated.
Eligible participants will have one eye scanned by each of 3 test devices. The entire visit is expected to take 3-4 hours and may be split over 2 visits if necessary.

Will you directly be compensated from the study?
Participants will be compensated up to $150, but there is not expected to be any direct benefit.

Other things you should know about the study:
If applicable, participants cannot receive any ocular treatments during the course of their study participation in the event the visit is split over 2 visits.
