PURPOSE: Our purpose was to compare the @entity5 sizes of small @entity3193 using ultra-widefield imaging (UWF) and different optical coherence tomography systems. METHODS: Thirteen @entity3193 were measured using automatic and manual segmentation techniques, including enhanced depth imaging spectral-domain optical coherence tomography (EDI-SDOCT) and 1050  nm swept source OCT (SSOCT), to compare to measurements obtained using the Optos projection ultra-widefield fundus (UWF) imaging technique. Segmentation artifacts were evaluated for all 13 cases, alongside an additional 12 @entity3193 , using SSOCT. RESULTS: In @entity5 eyes, segmentation artifacts for the choroid-sclera interface were found in 42  % of SSOCT scans. EDI-SDOCT can underestimate @entity5 dimensions and differs up to -8.41  % compared to UWF imaging and by 1.25  % compared to SSOCT cases. The horizontal length of the nevi showed an average difference between EDI-SDOCT and SSOCT of        9.38  %. Measured markers showed an average difference in length of        12.51  %. The average @entity5 thickness showed a difference of        11.47  %. Comparisons between EDI-SDOCT/UWF, SSOCT/EDI-SDOCT, and marker EDI-SDOCT/SSOCT showed significant mean differences of -122   m (CI: -212 to -31   m, p   =   0.013), 134   m (CI: 65-203   m, p   =   0.0012), and -193   m (CI: -345 to -41   m, p   =   0.017), whereas SSOCT/UWF showed no significant difference with a measurement of 13   m (CI: -69-95   m, p   =   0.74). CONCLUSIONS: @entity1347 requires much caution, because a @entity5 can trigger many artifacts. It would be beneficial to monitor @entity3193 using the same type of OCT technology, because a @entity5 is displayed differently.
