Changes of Peripapillary Region Perfusion in Patients with Chiasmal Compression Caused by Sellar Region Mass

Figure 1

A rectangle scanning area of 4.54.5 mm centered on the optic nerve head was measured. (a) The software automatically divides the round annular area, which was defined as peripapillary, into eight sectors, including nasal superior (NS), nasal inferior (NI), inferior nasal (IN), inferior tempo (IT), tempo inferior (TI), tempo superior (TS), superior tempo (ST), and superior nasal (SN). (b) The software evaluated the peripapillary vessel density (pVD) and RNFL thickness of the radial peripapillary capillaries (RPC) layer, which extends from the layer between the internal limiting membrane (ILM) to RNFL. The color map shows the vessel density (c) and the RNFL thickness (d). (e) The vessel density and RNFL thickness of each sector were quantified.
