Repeatability and reproducibility of vessel density measurements on optical coherence tomography angiography in diabetic retinopathy

Understanding the precision of measurements on and across optical coherence tomography angiography (OCTA) devices is critical for tracking meaningful change in disease. The purpose of this study is to investigate the repeatability and reproducibility of vessel area density and vessel skeleton density measurements from various commercial OCTA devices in diabetic eyes. Patients were imaged three consecutive times each on three different OCTA...
