Changes of Peripapillary Region Perfusion in Patients with Chiasmal Compression Caused by Sellar Region Mass

Table 4

Comparison of pVD and pRNFL thickness between patients with or without absolute central visual deficit and healthy controls.

	Group 1	Group 2	Group 3	value (1 versus 2)	value (1 versus 3)	value (2 versus 3)
pVD (%)	47.39 ± 7.48	52.42 ± 3.42	53.31 ± 2.21	0.027	<0.001	0.273
pRNFL thickness (μm)	96.63 ± 18.61	114.25 ± 19.82	118.41 ± 9.48	0.015	<0.001	0.178

Group 1, patients with an absolute defect in the central visual field. Group 2, patients without an absolute defect in the central visual field. Group 3, healthy controls. pVD = peripapillary vessel density. pRNFL = peripapillary retinal nerve fiber layer. Bold values are statistically significant values ().
