To compare the reproducibility of macular thickness measurements using Stratus OCT and state–of–the–art high speed, ultrahigh resolution OCT (spectral OCT, SOCT).
One randomly chosen eye of fifteen healthy subjects was scanned 3 times per day in 3 visits by single operator with Stratus OCT and SOCT. A Stratus OCT fast macular scan (6 radial scans, each with 128 A–scans) and a SOCT radial scan (24 radial scans, each with 1483 A–scans) were acquired. Intrasubject–intravisit and intrasubject–intervisit coefficient of variance (COV) and intraclass correlation coefficient (ICC) of overall macular thickness were computed for Stratus OCT and the 2 sets of SOCT data; comparing all 24 SOCT linear scans and using only 6 SOCT linear scans which corresponds to the Stratus OCT location.
Overall macular thickness reproducibility data are listed in the Table.
The SOCT demonstrated reproducible intra and intervisit measurements of macular thickness.
