Boldface indicates statistically significant difference.
*Measured in superior (46°–135°) and inferior (226°–315°) quadrants.
IOP, intraocular pressure; SBP, systolic blood pressure; DBP, diastolic blood pressure; MOPP, mean ocular perfusion pressure; HR, heart rate; RS, retinal sensitivity; RNFLT, retinal never fibre layer thickness; GCCT, ganglion cell complex thickness.
