Comparison of Fluorescein Clearance Test (FCT) Between FCT at Baseline and FCT at 1 Month After BTX-A Injection in Homolateral and Contralateral Eye

	Baseline (n= 30)	1-Month Follow-Up (n=27)	P
Homolateral eye
Basal tear secretion (mm), median (Q1,Q3)†	3.5 (2,6)	5 (1,9)	0.424
Delayed tear clearance (%)#	20 out of 26 (76.92%)	24 out of 26 (92.31%)	0.103
Reflex tear (%)#	17 out of 26 (65.38%)	11 out of 26 (42.31%)	0.083
Contralateral eye
Basal tear secretion (mm), median (Q1,Q3)†	2.75 (1,7)	3 (1,6)	0.308
Delayed tear clearance (%)#	16 out of 26 (61.54%)	21 out of 26 (80.77%)	0.059
Reflex tear (%)#	16 out of 26 (61.54%)	17 out of 26 (65.38%)	0.706
