Annular Array Ultrasound in Ophthalmology
United States30 participantsStarted 2011-10
Plain-language summary
The objective of this research is to improve the care of ocular disease and disorders, in particular the changes in the eye associated with diabetes, by providing clinicians with dramatically improved ultrasonic images of the entire eye. The research combines advanced high-frequency, high-resolution ultrasonic annular arrays transducers with new processing techniques designed to overcome several limits that have been reached with conventional high frequency ultrasound systems. The investigators propose that diagnosis of eye diseases using annular arrays can be more effective than the conventional ultrasound images by at least 50%; i.e., that for every 2 posterior vitreous detachments detected conventionally, 3 will be detected with the annular arrays.

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.
1This study compared a 20MHz annular array ultrasound to a standard 10MHz single-element ultrasound for detecting posterior vitreous detachment — could you explain what that difference in technology might mean for how accurately my eye condition gets diagnosed?
2Since this trial is already completed, have the results been published, and if so, do they suggest that the newer annular array ultrasound is more reliable for detecting posterior vitreous detachment in people with diabetic retinopathy like me?
3Is the 20MHz annular array ultrasound being used in your practice or at this facility, and should I ask for it specifically when getting an ultrasound evaluation of my eyes?
4Given that this was a diagnostic study — not a treatment trial — how would getting a more precise ultrasound image actually change the treatment decisions you'd make for my condition?
5For someone with both diabetic retinopathy and a possible posterior vitreous detachment, what are the standard imaging tools you currently use, and is there any reason to seek out a center that has access to this newer annular array technology?

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
Change in detection of posterior vitreous detachment: 20MHz annular array versus 10MHz single element
Timeframe: Subjects will be examined with both the 20MHz annular array and 10MHz single element ultrasound during the same exam, approximately 30 minutes in duration.
