COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Titles & IDs
Public title
A randomised control trial to determine if the review of non-mydriatic retinal images can contribute to a reduction in glycosylated hemoglobin in patients with poor control of their blood sugar diabetic retinopathy
Scientific title
A Prospective randomized control trial to determine if the review of nonmydriatic retinal images in poorly controlled diabetic patients with diabetic retinopathy at the time of endocrinology visit can lower glycosylated hemoglobin (HbA1C).

Study type
Description of intervention(s) / exposure
The “intervention” group will have a nonmydriatic imaging of each retina (45 degrees one field centered between fovea and optic nerve head) following their endocrinologist exam, followed by a brief discussion by a retina specialist about the findings. The patients will be shown their images during this discussion and the following topics will be explicitly discussed with each patient: First, a series of images comprising a spectrum starting from a normal appearing fundus to images of mild and moderate nonproliferative diabetic retinopathy (DR), active proliferative DR and tractional retinal detachment. Second, ongoing blood glucose control will be stressed in order to delay or avoid worsening of their retinopathy and finally a brief summary of the results of the Diabetes Control and Complications Trial (DCCT) and United Kingdom Prospective Diabetes Study (UKPDS) regarding HbA1C control and DR.

Early detection / Screening
Comparator / control treatment
The “control” group would differ in that they will not have the imaging following their endocrinologist exam and will not have a discussion with the retinal specialist. These patients will be evaluated according to their previously determined, regularly scheduled ophthalmology follow up. Diabetic eye care will be otherwise the same in both groups.
