AB  - The measurement of the optic nerve sheath diameter (ONSD) by ultrasonography 
      (USG) is particularly important for intracranial pressure (ICP) monitoring when 
      invasive measurements are not possible or are contraindicated. Standard USG 
      (SUDs) devices can be bulky and may break down the workflow. The validity and 
      reliability of pocket-sized USG devices (PSUDs) compared to SUDs for ONSD 
      measurement has not been investigated, yet. We compared the reliability and 
      validity of PSUDs with SUDs for ONSD measurement. 35 patients were included in 
      the study. ONSD measurements with PSUDs and SUDs were performed by two clinicians 
      as three different measurements in both sagittal and transverse axis of the eye. 
      There was agreement between mean transverse ONSD (mtONSD), mean sagittal ONSD 
      (msONSD), and mean ONSD(mONSD) values measured with each device according to 
      Bland-Altman test (p = 0.166, p = 0.135, p = 0.066, respectively) with no 
      proportional bias (p = 0.544, p = 0.868, p = 0.929, respectively). Intraclass 
      correlation coefficients (ICC) were found to be greater than 0.7 for mtONSD, 
      msONSD, and mONSD values measured by SUD (ICC = 0.790, ICC = 0.817, and 
      ICC = 0.844, respectively). Similarly, for mtONSD, msONSD, and mONSD values 
      measured by PSUD, ICC were found greater than 0.7 (ICC = 0.763, ICC = 0.814, and 
      ICC = 0.843, respectively). There was no statistically significant difference 
      between mtONSD and msONSD (p = 0.441 for SUD and p = 0.893 for PSUD). There was a 
      good correlation between mtONSD and msONSD (r = 0.767 for SUD and r = 0.816 for 
      PSUD). The total variance between three different measurements in the transverse 
      and sagittal axis was +/- 0.6 mm. PSUDs can be used with similar validity and 
      reliability as SUDs for ONSD measurement.
