Comparison of ophthalmic variables between cases and control.

Variables	Groups		value
	Cases (); (mean ± SD)	Control (); (mean ± SD)
VA	0.41 ± 0.29	1.00 ± 0.00	0.001
RE (D)	3.51 ± 1.88	1.88 ± 1.11	0.001
FVS (dB)	25.92 ± 6.88	33.48 ± 1.75	0.001
CDRP	66.00 ± 16.98	28.50 ± 5.80	0.001
IOP (mmHg)	19.55 ± 2.08	11.65 ± 1.64	0.001
AVFMD (dB)	−9.63 ± 10.58	0.07 ± 1.54	0.001
AVFPSD (dB)	4.13 ± 6.96	1.64 ± 0.45	0.001

VA = visual acuity in decimal system; RE = refractive error; FVS = foveal visual sensitivity; CDRP = cup-disc ratio in percent; IOP = intraocular pressure; AVFMD = automated visual field mean deviation; AVFPSD = automated visual field pattern standard deviation.
