Stratus Versus Cirrus OCT in AMD

December 4, 2007 updated by: The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery

Reliability of Threshold Algorithm in Age-Related Macular Degeneration: Stratus Versus Cirrus OCT

The Cirrus OCT provides due to the spectral domain technology a 2-fold resolution than Stratus OCT generated in a comparable amount of time. Due to this higher resolution the retinal surface and the retinal pigment epithelium can be identified more clearly, a significantly reduced number of algorithm failures is expected
