Showing the number and percentage of patients on glaucoma medication and mean values±SD of mean deviation (MD) and pattern SD (PSD) of patients in the groups of ocular hypertension (OHT), high-tensions glaucoma (HTG) and normal-tension glaucoma (NTG)

	OHT	HTG	NTG	P value
Prostaglandin analogues	31 (58.5%)	37 (78%)	23 (69.7%)	0.260
β-blockers	7 (13.2%)	20 (42.5%)	11 (30.5%)	0.058
CA-inh	5 (9.4%)	17 (36.1%)	10 (27.7%)	0.053
α agonist	3 (5.7%)	4 (8.5%)	1 (2.8%)	0.837
Mean Deviation	−1.46±1.90	−7.60±8.45	−6.79±6.28	<0.001
Post hoc p value	<0.001	1.000
Pattern Standard Deviation	1.99±1.36	8.40±10.75	6.58±3.88	<0.001
Post hoc p value	<0.001	0.199

P values express the difference between the groups. When applicable post hoc p values are between NTG and the other groups.
