Retinal Thickness and Volume Estimates Given by Time Domain and Spectral Optical Coherence Tomography

Retinal Thickness and Volume Estimates Given by Time Domain and Spectral Optical Coherence Tomography

The purpose of the present study is to determine if the retinal thickness estimates of the Stratus OCT, the 3D OCT-1000, and the CirrusHD OCT are comparable in diabetic and in healthy individuals (OCT=Optical Coherence Tomography).

Inclusion Criteria:

• diabetic retinopathy in the diabetic group
• healthy retinas in the healthy group

Exclusion Criteria:

• not able to cooperate
• retinal disease other than macular oedema
• severe media opacities (e.g. cataract)
• prior macular laser photocoagulation except for large oedemas
