Fig 1.
Diurnal IOP fluctuation in PACG and POAG patients.
(A) The mean diurnal IOP profiles of 31 PACG patients. (B) The mean diurnal IOP profiles of 22 POAG patients. (C) The diurnal IOP profile of PACG group. The IOP at 08:00 was significantly higher than that at 20:00 (p = 0.001) and 24:00 (p = 0.001). (D) The diurnal IOP profile of POAG group. The IOP at 08:00 was significantly higher than that at 16:00 (p = 0.004), 20:00 (p = 0.004) and 24:00 (p < 0.001) and the IOP at 24:00 was significantly lower than 12:00 (p < 0.001), 16:00 (p = 0.004) and 20:00 (p = 0.002). (E) The frequency of peak diurnal IOP measured in PACG patients. The measurement at 8:00 was higher than that at 20:00 (p = 0.003) and 24:00 (p = 0.001). (F) The frequency of peak diurnal IOP measured in POAG patients. The measurement at 08:00 was higher than that at 16:00 (p = 0.003) and 24:00 (p = 0.001). (G) The frequency of trough diurnal IOP counted in PACG patients. (H) The frequency of trough diurnal IOP counted in POAG patients.
