Association between Optic Nerve Head Microcirculation and Macular Ganglion Cell Complex Thickness in Eyes with Untreated Normal Tension Glaucoma and a Hemifield Defect

Table 2

Comparisons between normal and defective hemifields for total deviations, optical coherence tomography measurements, and optic nerve head microcirculation parameters.

	Defective hemifield	Normal hemifield
Average TD (dB)	−6.0 ± 6.8	−0.4 ± 1.6	<0.001
Average TD (1/Lambert)	0.4 ± 0.3	1.0 ± 0.3	<0.001
mGCC (μm)	75.6 ± 8.0	88.1 ± 8.3	<0.001
cpRNFL (μm)	74.3 ± 8.4	89.0 ± 11.7	<0.001
MBRA (AU)	18.3 ± 4.5	20.1 ± 5.0	<0.001
MBRV (AU)	39.8 ± 8.0	41.7 ± 9.0	0.003
MBRT (AU)	9.7 ± 2.0	10.3 ± 2.2	<0.001

Statistical significance determined with two-tailed, paired t-tests. AU: arbitrary units; cpRNFL: circumpapillary retinal nerve fiber layer; MBR_A: mean blur rate in all area; MBR_V: mean blur rate in vessel area; MBR_T: mean blur rate in tissue area; mGCC: macular ganglion cell complex; TD: total deviation.
