Abstract Details


To evaluate the influence of water drinking test (WDT) on central corneal thicknesses (CCT), anterior chamber depth (ACD) and axial length (AL) using optical low-coherence reflectometer.


Abant Izzet Baysal University, Faculty of Medicine, Department of Ophthalmology


30 healthy male adult subjects, with a mean age of 28.13 ± 3.38 years (range, 23 to 39) and having less than 5 diopters of spherical and less than 3 diopters of cylindrical refractive error, participated in this study. The CCT, ACD and AL were measured using optical low-coherence reflectometer (Lenstar LS 900, Haag-Streit AG, Koeniz, Switzerland) before, 15, 30 and 45 min after water loading. Repeated measures analysis of variance test was used for statistical analysis.


Thirty eyes were included in the study. We did not observe any statistically significant changes in CCT, ACD and AL (p values were 0.214, 0,802 and 0.714). An increase in IOP was observed during WDT but only IOP increase between 0 and 15 min was statistically significant (p=0.004). Pearson correlation analysis test did not identify any significant correlation for changes in IOP, CCT, ACD and AL between 0 and 15 min (p values were ranging between 0.138-0.649).


This study revealed increase in IOP after WDT. However, CCT, ACD and AL did not differ significantly during WDT. There was no association of changes in IOP, CCT, ACD and AL.
