Table 4 The correlation between peripapillary vessel density and glaucomatous related factors

From: Peripapillary vessel density measurement of quadrant and clock-hour sectors in primary angle closure glaucoma using optical coherence tomography angiography

  Peripapillary vessel density
r P
Age (year) -0.213 0.181
Sex 0.092 0.569
IOP (mmHg) -0.178 0.264*
Mean OPP (mmHg) 0.098 0.544
RNFL thickness (μm) 0.753 <0.001
VF MD (dB) 0.691 <0.001*
  1. Unless otherwise illustrated, correlation analysis was made by using Pearson correlation test
  2. IOP intraocular pressure, OPP ocular perfusion pressure, RNFL retinal nerve fiber layer, VF MD visual field mean deviation
  3. *Correlation analysis was made by using Spearman correlation test
