Data are presented as mean ± standard deviation for all subjects in each group. RPC-VD = radial peripapillary capillary vessel density; Control or C = control eyes; TAO = thyroid-associated ophthalmopathy; DON = dysthyroid optic neuropathy; NDON or N = non-DON; EDON or E = equivocal DON; ST = superior temporal; SN = superior nasal; TU = temporal upper; TL = temporal lower; IT = inferior temporal; IN = inferior nasal; NL = nasal lower; NU = nasal upper; P values in bold indicate statistical significance
