Evaluation of the Effect of Hypercapnia on Vascular Function in Normal Tension Glaucoma

Table 1

Demographic comparison of patients with normal tension glaucoma (NTG) and healthy volunteers (control).

	NTG; ()	Controls; ()	value
Age (years)	58.72 ± 10.0	57.5 ± 9.6	0.71
Sex (M : F)	11 : 9	9 : 9
Ax. L (mm)	24.03 ± 1.22	23.6 ± 0.89	0.27
IOP (mmHg)	16.6 ± 2.97	14.31 ± 3.2	0.12
MAP (mmHg)	103.45 ± 13.53	95.96 ± 12.88	0.11
HR (b/min)	66.7 ± 13.06	72.75 ± 14.59	0.22
CVS disease	8	3	0.092
Hypovol/Hypoten	5	0	0.018
Vasospasm	11	3	0.008

Results are mean ± standard error mean and were compared using -test. Male to female ratio (M : F); intraocular pressure (IOP) in millimetres of Mercury (mmHg); axial length (Ax. L) in millimetres (mm); mean arterial blood pressure (MAP); heart rate (HR) in beats per minute (b/min); cardiovascular disease (CVS disease); history of hypovolaemia or hypotension (Hypovol/Hypoten).
