Comparison of mean pre-OCT-A features of the eyes of patients in the study group and the eyes of the subjects in the control group (study group, n = 58; control group, n = 60).

BCVA (decimal)	0.99 ± 0.067	1.00 ± 0.00	0.232
CAS	0.10 ± 0.41	0.00 ± 0.00	0.051
IOP (mmHg)	16.88 ± 2.28	15.02 ± 2.56	0.001
SE (D)	−0.25 ± 0.90	−0.09 ± 3.75	0.200
PROP (mm)	12.31 ± 1.70	11.58 ± 0.49	0.002
CCT (μm)	549.64 ± 29.31	546.35 ± 33.96	0.575
AXL (mm)	23.02 ± 1.03	22.63 ± 0.42	0.008

Statistical analysis was calculated by independent samples t-test, statistically significant, BCVA: best-corrected visual acuity, CAS: clinical activation score, IOP: intraocular pressure, SE: spherical equivalent, PROP: proptosis level, CCT: central corneal thickness, AXL: axial length, BUT: breakup time, and sc: second.
