Figure 2
Changes in optic nerve sheath diameter. Values are expressed as estimated mean ± standard error values from linear mixed model. *The linear mixed model revealed that there were statistically significant between-group differences in changes in ONSD according to time (model corrected for age, gender, height, weight, end-tidal sevoflurane and carbon dioxide levels, and peak inspiratory pressure; PGroup × Time = 0.045). T0, before starting the pump; T1, 3 min after starting the pump; T2, 10 min after starting the pump; T3, 70 min after starting the pump.
