    Dense B-scan Optical Coherence Tomography Angiography

    Purpose To describe a novel imaging technique, we call “dense B-scan optical coherence tomography angiography” (DB OCTA) in which thin dense raster scans are used to produce highly resolved structural B-scans with superimposed flow signal that provide precise correlation between retinal microstructure and blood flow. Design Observational case series Methods Normal eyes and eyes with macular findings of interest were imaged with DB OCTA in which 150-400 OCT B-scans were acquired within a narrow area (from a single line to 1°) with a width of 10 to 30°. B-scans containing 5-7 consecutive frames were processed for OCTA signal and then ...
