Abstract |
PURPOSE This study was performed to compare macular retinal thickness measured by four different optical coherence tomography (OCT) devices. METHODS: Macular retinal thicknesses were measured in 32 healthy eyes of 32 subjects by using Cirrus HD-OCT (Carl Zeiss Meditec, Inc., Dublin, CA, USA), Spectralis OCT (Heidelberg engineering, Heidelberg, Germany), Topcon DRI OCT (Topcon Corp., Tokyo, Japan), and RS-3000 Advance OCT (Nidek, Co., Ltd., Gamagori, Japan). Macular retinal thickness measurements were compared among the devices. RESULTS: Average macular retinal thickness ranged 288.7 to 313.3 µm (p < 0.01). Differences in average macular retinal thickness among the devices ranged from 0.7 to 27.3 µm; the limit of agreement (LoA) ranged from 9.7 to 24.4 µm. Among the devices, comparison between Spectralis OCT and RS-3000 Advance OCT showed the smallest difference in average macular retinal thickness (mean, 0.7 µm) and the narrowest LoA (−6.4 to 3.3 µm). CONCLUSIONS: Macular retinal thickness measured by four different OCT devices showed different values. However, values obtained by Spectralis OCT and RS-3000 Advance OCT showed good agreement. |
