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

Table 5

Multivariate linear regression analysis of the effects of tumor diameter and symptom duration on BCVA, pVD, and pRNFL thickness.

	BCVA		pVD		pRNFL thickness
	β	p	β	p	β	p
Transverse diameter	−0.050	0.058	−0.074	0.849	0.947	0.418
Anteroposterior diameter	−0.021	0.366	−0.139	0.686	−0.781	0.449
Vertical diameter	0.051	0.029	−0.098	0.772	−0.876	0.390
Symptom duration	−0.001	0.935	0.065	0.618	0.498	0.208

BCVA = best-corrected visual acuity. pVD = peripapillary vessel density. pRNFL = peripapillary retinal nerve fiber layer. Bold values are statistically significant values ().
