Diurnal IOP fluctuation in PACG and POAG patients.

<p><b>(A)</b> The mean diurnal IOP profiles of 31 PACG patients. <b>(B)</b> The mean diurnal IOP profiles of 22 POAG patients. <b>(C)</b> The diurnal IOP profile of PACG group. The IOP at 08:00 was significantly higher than that at 20:00 (<i>p</i> = 0.001) and 24:00 (<i>p</i> = 0.001). <b>(D)</b> The diurnal IOP profile of POAG group. The IOP at 08:00 was significantly higher than that at 16:00 (<i>p</i> = 0.004), 20:00 (<i>p</i> = 0.004) and 24:00 (<i>p</i> < 0.001) and the IOP at 24:00 was significantly lower than 12:00 (<i>p</i> < 0.001), 16:00 (<i>p</i> = 0.004) and 20:00 (<i>p</i> = 0.002). <b>(E)</b> The frequency of peak diurnal IOP measured in PACG patients. The measurement at 8:00 was higher than that at 20:00 (<i>p</i> = 0.003) and 24:00 (<i>p</i> = 0.001). <b>(F)</b> The frequency of peak diurnal IOP measured in POAG patients. The measurement at 08:00 was higher than that at 16:00 (<i>p</i> = 0.003) and 24:00 (<i>p</i> = 0.001). <b>(G)</b> The frequency of trough diurnal IOP counted in PACG patients. <b>(H)</b> The frequency of trough diurnal IOP counted in POAG patients.</p
