Twenty-Four-Hour Variation of Intraocular Pressure in Primary Open-Angle Glaucoma Treated with Triple Eye Drops

Table 2

Comparison of background factors between diurnal and nocturnal types of IOP profile. Data are expressed as mean ± SD. Significant differences in spherical equivalent, variation of IOP and IOP at 10:00 were observed between diurnal and nocturnal types.

Age (y)	51.9 ± 10.5	56.1 ± 14.1	0.18
Spherical equivalent (D)	−5.7 ± 4.0	−4.0 ± 4.0	0.014
Mean deviation (dB)	−10.8 ± 8.6	−11.7 ± 9.3	0.81
24-hour fluctuations of IOP (mmHg)	3.1 ± 1.1	4.2 ± 2.0	0.01
IOP at 10:00 (mmHg)	14.1 ± 2.4	12.7 ± 2.4	0.01
