The Spectralis-Cirrus Study

Comparison of Quality and Reproducibility of Retinal Thickness Measurements in Two Spectral Domain OCT- Machines

Retinal thickness measurement is one of the most important examinations in the follow up of exudative age-related macular degeneration. Prior studies have shown that there are a series of algorithm line failures in OCT examinations. This study is conducted to compare the quality of the examinations of to different spectral domain OCT machines concerning the positioning of algorithm lines. Furthermore the reproducibility of the examinations id tested, both machines provide different techniques to guarantee that in repeated examinations the same location is examined.

Inclusion Criteria:

• Exudative age related macular degeneration

Exclusion Criteria:

• Macular pathologies other than age related macular degeneration (diabetic maculopathy, macular pucker, macular hole,
• Visualization of the macula not possible (dens cataract, vitreous haemorrhage)
• Not consented patients
