Select the Superficial preset (see Presets "CIRRUS OCT Angiography Presets" on
page 9-4) from the OCT Angiography Analysis screen (for 3x3 and 6x6 scans only) to
bring up tools for observing and measuring vessel density and/or capillary perfusion. (For
ONH Angiography, see Figure 9-3.) Measuring capillary non-perfusion or impaired
capillary perfusion can be useful in case of macular ischemia caused by vascular
pathologies including but not limited to Diabetic Retinopathy.
