  • Boldface indicates statistically significant difference.

  • *Measured in superior (46°–135°) and inferior (226°–315°) quadrants.

  • †Calculated as Pearson correlation coefficient, with p<0.05 considered to be statistically significant.

  • RNFLT, retinal never fibre layer thickness; GCCT, ganglion cell complex thickness; RS, retinal sensitivity; TA, temporal artery; TV, temporal vein.
