Structural and functional markers of neuro-retinal complications in adolescents with early type 2 diabetes

Name of Applicant

Aparna Bhan

Institutions involved

Hospital for Sick Children

Investigator: Dr. Carol Westall

Funding source

Canadian Institutes of Health Research (CIHR)

Inclusion Criteria

  • Subjects from ages 12 to 30 years
  • Individuals without AND individuals with type 1 diabetes

Participation involves one 3-hour session involving various non-invasive vision tests. Participants should be comfortable with getting eye drops (dilation), which may cause blurry vision for 2 to 3 hours.

Participants will be compensated for their time. This is also an opportunity for high school students to earn community service hours.


Some patients with diabetes develop a condition called diabetic retinopathy. Diabetic retinopathy affects vision, and is difficult to treat once it starts. Our team is looking for new ways to identify changes in the eye before diabetic retinopathy begins. We are using a brand new instrument that allows us to see individual cells in the eye. We are also using several other tools to test eye function. Looking at structure and function, together, we hope to solve the puzzle of diabetic retinopathy.
