      Optical coherence tomography angiography findings in diabetic retinopathy
      Introduction : Diabetic retinopathy (DR) is a common complication of diabetes and a leading cause of blindness in working age population. Fluorescein angiography is still the gold standard in the evaluation of retinal vascular perfusion and diagnosis of macular ischemia. However, it is a costly, time-consuming procedure and it requires intravenous injection of contrast agent, exposing patients to potential side effects. Optical coherence tomography angiography (OCTA) is a novel, non-invasive imaging ...

    1. With CIRRUS FastTrac, I can place a highest resolution 20x B-Scan precisely on the area I am treating at each successive visit to see the fine details of the patient’s response to treatment...It’s also very helpful for removing any eye motion from the larger cube scans without disturbing my patient flow because it works so quickly. My initial experience is that FastTrac is about 30 percent faster than other tracking methods I have used.
