Aim: To compare macular thickness measurements with spectral-domain (Cirrus HD-OCT) and time-domain (StratusOCT) optical coherence tomography. Method: Macular thickness was measured in nine ETDRS subfields in the same eye of 20 healthy subjects using both instruments. Using Cirrus HD-OCT both the Macular Cube 512×128 and Macular Cube 200×200 protocol, using StratusOCT the Fast Macular Thickness Map protocol was performed. Reproducibility of all three measurement series was assessed and the average of the measurement series was compared on each field. Results: Measurement values obtained by StratusOCT were significantly lower than those obtained by Cirrus HD-OCT (p<0.001) in all subfields. Correlation coefficient between the results obtained by the two protocols of Cirrus HD-OCT was 0.977. Conclusions: By using Cirrus HD-OCT we could observe better repeatability than with StratusOCT. Using Cirrus HD-OCT significantly higher measurement values could be obtained in all subfields than those measured with Stratus. Using different OCT instruments we get significantly different values, therefore care needs to be taken when comparing data. Orv. Hetil., 154(52), 2059–2064.

Purpose. To compare the macular thicknesses in diabetic macular edema (DME) measured with spectral-domain optical coherence tomography (SD-OCT) and time-domain (TD) OCT.Patients and Methods.The average macular thicknesses of 50 eyes of 29 patients with DME were measured using SD-OCT and TD-OCT.Results.The mean macular thicknesses measured with TD-OCT and SD-OCT were401.5±117.8 μm (mean ± SD) and446.2±123.5 μm, respectively. The macular thicknesses measured with the two devices were well correlated (Pearson's product moment correlation,r=0.977,P<0.001). A significant correlation was found between the best-corrected visual acuity and the retinal thickness measured by TD-OCT and SD-OCT (Pearson's product moment correlation, TD-OCT,r=0.34;P<0.05; SD-OCT,r=0.32;P<0.05).Discussion.The mean macular thickness measured with SD-OCT was about 45 μm thicker than that measured with TD-OCT. Attention should be paid when comparing data obtained using different OCT machines.
