OCT Angiography

OCT angiography is a novel imaging technology designed to create a map of retinal blood vessels. It is commonly utilised by Dr Chauhan  for conditions that affect retinal vasculature, and is the first of its kind to be used within clinical practice in Victoria.

The information OCT angiography provides is similar to traditional fluorescein angiography, and in some circumstances displays comparably higher resolution of retinal blood vessels. These images are captured in the same way as regular OCT images taking only a few seconds to acquire, whilst not requiring dye injections associated with fluorescein angiography

As with standard OCT imaging, OCT angiography is used in the diagnosis and ongoing treatment of retinal conditions such as macular degeneration and diabetic retinopathy, and can be repeated as required without discomfort.
