Answer

Laboratory studies of HbA1c levels are important in the long-term follow-up care of patients with diabetes and diabetic retinopathy.

Imaging studies used in the diagnosis of diabetic retinopathy include the following:

  • Fluorescein angiography: Microaneurysms appear as pinpoint, hyperfluorescent lesions in early phases of the angiogram and typically leak in the later phases of the test

  • Optical coherence tomography scanning: Administered to determine the thickness of the retina and the presence of swelling within the retina, as well as vitreomacular traction

  • B-scan ultrasonography

See Workup for more detail.
