Representative OCTA images of the control, NDON, EDON, and DON groups. a–d Peripapillary vessel density maps from eyes representative of control, NDON, EDON, and DON groups. e–h P-RNFL in the Garway-Heath map sectors (radius = 1.00 mm from the optic disc boundary) i–l Circum-papillary vascular density of the RPC layer with the Garway-Heath map sectors. OCTA, optical coherence tomography angiography; DON, dysthyroid optic neuropathy; NDON, non-DON; EDON, equivocal DON; p-RNFL, peripapillary retinal nerve fiber layer; SN, superior nasal; ST, superior temporal; NU, nasal upper; NL, nasal lower; IT, inferior temporal; IN, inferior nasal; TL, temporal lower; TU, temporal upper
