“…Over the course of a single day, the IOP of both eyes was measured on four occasions (at 9:00 a.m., 12:00 a.m., 3:00 p.m., and 6:00 p.m.), always after resting for 15 minutes in a seated position [5,12,13]. The measurements were also performed in the sitting position by the noncontact tonometer Canon TX-10 (Canon Inc., Tokyo, Japan), which determines the mean IOP value automatically by taking three measures of the patient's cornea deformation when blowing an air pulse [14].…”

To compare intraocular pressure (IOP) values at different time points, both in the total sample and according to iridocorneal angle aperture, to assess whether IOP fluctuations were constant throughout the day, and to examine correlations with other factors. MethodsOver a single day, the IOP of 34 volunteers was measured at three-hour intervals from 9:00 a.m. to 6:00 p.m. To avoid any IOP value being affected by other measurements, anamnesis, slit-lamp evaluation (with iridocorneal angle measurement), and refractive status were performed after the final measurement. The differences between IOP values at different time points and IOP fluctuation at three-hour intervals were compared by ANOVA and Friedman test, respectively, both for the total group and according to iridocorneal angle aperture. For relationships, Pearson's correlation was performed for parametric variables and Spearman's correlation for nonparametric variables. ResultsSignificant differences were observed in IOP between time points for the total sample (p < 0.001), but not for a narrow-angle group (p = 0.058). No significant differences were found in IOP fluctuations at three-hour intervals either in the total sample or according to angle aperture (all p ≥ 0.332). There was a positive correlation of IOP at different time points (all r ≥ 0.646, all p < 0.001) but no relationship with spherical equivalent, age, or sleep duration (all p ≥ 0.057). IOP at 12:00 p.m. was correlated with a 12:00 p.m. to 3:00 p.m. fluctuation (r = 0.428, p = 0.012); and IOP fluctuation between 9:00 a.m. and 12:00 p.m. was correlated with age (r = 0.485, p = 0.004). ConclusionAs IOP decreases from morning until at least 6:00 p.m., measuring these two values during clinical evaluation is essential for the effective monitoring and prevention of IOP-related diseases.

Purpose To study response to water drinking provocation in primary open angle glaucoma (POAG), ocular hypertensives and glaucoma suspects and establish the role of water drinking provocation test (WDPT) as a relevant supplementary tool in glaucoma management. Materials and methods 319 eyes of 161 patients were included in the study after retrospectively analyzing hospital records of patients who underwent WDPT. The patients were categorized into Group A (POAG on treatment), Group B (treatment-naïve POAG), Group C (Ocular hypertensives), Group D (glaucoma suspects). All patients were asked to drink 1 liter of water within 5 min and intraocular pressures (IOP) were recorded after 20 and 30 min of water intake. The baseline, peak and IOP fluctuation were analysed. A fluctuation of ≥ 5 mm Hg was considered positive response. Results 19 eyes were categorized as Group A, 58 as Group B, 96 and 146 eyes as groups C and D respectively. Baseline IOP in different groups differed significantly. Mean peak IOP was higher in Groups B and C, followed by Groups A and D. Mean IOP fluctuation differed significantly across groups being maximum in Group A (7.0 ± 2.5) and minimum in Group D (4.8 ± 2.9). Positive WDPT response was seen in 89.5% eyes in Group A, 77.6% of those in Group B, 55.2% and 48.6% in Groups C and D respectively. The baseline IOP had a significant positive correlation with the peak IOP across all groups. Conclusion The WDPT is an inexpensive practical tool which serves as an invaluable aid in glaucoma management.
