The Primary objective is to determine the accuracy of the microconvex ultrasound transducer as compared to the linear ultrasound transducer for ultrasound measurement of the optic nerve sheath diameter compared to CT measurements.
To determine the accuracy of the microconvex ultrasound transducer as compared to the linear ultrasound transducer for ultrasound measurement of the ONSD/ETD compared to CT measurements.
To determine the accuracy of the microconvex ultrasound transducer as compared to the linear ultrasound transducer for ultrasound measurement of the eyeball transverse diameter compared to CT measurements.
To determine the level of intra- and inter-rater variability for ultrasound measurement of the optic nerve sheath diameter between the two transducer types.
