Fig 1.
Examples of Topcon SS-OCT reports for each scan in a healthy eye.
(A) Wide scan report, (B) standard macula scan report and (C) standard disc scan report. Wide report provides both macular and circumpapillary parameters.
Table 1.
Demographics and ocular data including macular ganglion cell layer plus inner plexiform layer (mGCIPL), mGCIPL plus nerve fiber layer (mGCC) and total retinal layer (TRL) measurements by swept source optical coherence tomography (SS-OCT) wide scan and standard macula scan, and circumpapillary retinal nerve fiber layer (cpRNFL) measurements by SS-OCT wide scan and standard disc scan of normal subjects and glaucoma patients.
Table 2.
Repeatability of wide and standard macula scan measurements of macular thickness, and wide and standard disc scans for circumpapillary retinal nerve fiber layer (cpRNFL) thickness parameters.
Fig 2.
Dot plot graphs with the values from the wide and standard macular/disc scan measurements.
Total (average) thickness of (A) ganglion cell layer plus inner plexiform layer (mGCIPL) and (B) macular ganglion cell layer (mGCC), measured by wide scan (X axis) and standard macula scan (Y axis), and total (average) thickness of (C) circumpapillary retinal nerve fiber layer (cpRNFL), measured by wide scan (X axis) and standard disc scan (Y axis), in normal and glaucoma groups are shown.
Fig 3.
Bland-Altman plots of each macular layer thickness (mGCIPL, mGCC and TRL) and cpRNFL thickness.
The plots also show significant correlations in cpRNFL, mGCIPL and mGCC thickness that the difference (Wide–Standard macula or disc) is larger as the measurement value becomes thicker.
Table 3.
Agreement between wide and standard macula scan measurements for macular thickness parameters, and wide and standard disc scan for circumpapillary retinal nerve fiber layer (cpRNFL) thickness parameters.
Table 4.
Comparison of areas under the receiver operating characteristic curves (AUCs) between wide and standard macula scans of macular thickness parameters and between wide and standard disc scans of circumpapillary retinal nerve fiber layer (cpRNFL) thickness parameters for assessing glaucoma.
