11/11/2022 0 Comments Stratus optical coherence tomographyTherefore a conversion formula is necessary to compare Stratus and Cirrus OCT CRT values, and this has been determined in our study. The commercially available optical coherence tomogram (Stratus OCT III) designed for posterior segment imaging can be used for central corneal thickness (CCT) measurement. Stratus OCT and Cirrus OCT use a different posterior reference line within the hyper-reflective band of the outer retina. For RV the formula Cirrus OCT RV=3.098+0.98 × Stratus OCT RV was calculated. The correlation was significantly influenced by the height of the CRT values (p<0.0001), but not by whether correction was necessary. An optical coherence may be changes in alignment between the two sets of scans tomography-guided, variable dosing regimen with intravitreal resulting from fixation instability, making it difficult to ensure ranibizumab (Lucentis) for neovascular age-related macular degen- that the same retinal area is scanned each time. For CRT the formula Cirrus CRT=58.63+0.94 × Stratus CRT was calculated. Stratus and Cirrus OCT CRT were significantly correlated (p<0.0001). OCT examinations of 104 eyes of 104 patients were reviewed and corrected when necessary. A linear model with Stratus OCT CRT as fixed factor and Cirrus OCT CRT as dependent variable was applied to calculate the conversion formula. The reports generated by the Stratus fast. Our aim was to determine a formula to convert Stratus OCT (TD OCT) to Cirrus OCT (SD OCT) retinal thickness.Ĭentral retinal thickness (CRT) and retinal volume (RV) were obtained by the macular thickness program of Stratus OCT and the cube 512 × 128 program of Cirrus OCT in patients with exudative age-related macular degeneration (AMD). The cross sectional optical coherence tomography images have an important role in evaluating retinal diseases. Reproducibility of Optovue RTVue Optical Coherence Tomography Retinal Thickness Measurements and Conversion to Equivalent Zeiss Stratus Metrics in Diabetic. Spectral domain optical coherence tomography (SD OCT) is of increasing importance and is gradually replacing time domain OCT (TD OCT). RESULTS: Using Stratus optical coherence tomography, we found significantly lower values in both macular thickness and volume over outer superior, outer nasal, outer inferior, inner temporal and inner inferior regions in highly myopic eyes with early to moderate glaucoma than in the control group.
