    1. Comparison of Optical Coherence Tomography Retinal Thickness Measurements in Diabetic Macular Edema with and without Reading Center Manual Grading from a Clinical Trials Perspective.

      Title: Comparison of Optical Coherence Tomography Retinal Thickness Measurements in Diabetic Macular Edema with and without Reading Center Manual Grading from a Clinical Trials Perspective. Invest Ophthalmol Vis Sci. 2008 Jun 19; Authors: Glassman AR, Beck RW, Browning DJ, Danis RP, Kollman C Purpose: To analyze the value of reading center error correction in automated Optical Coherence Tomography (OCT) retinal thickness measurements in eyes with diabetic macular edema (DME). Methods: 6,522 Zeiss Stratus OCT scans obtained in 7 DRCR.net studies were analyzed. The Reading Center evaluated whether the automated center point measurement appeared correct, and when not, it ...

    2. Comparison of Time-Domain OCT and Fundus Photographic Assessments of Retinal Thickening in eyes with Diabetic Macular Edema.

      Abstract Purpose: To explore the correlation between optical coherence tomography (OCT) and stereoscopic fundus photographs (FP) for the assessment of retinal thickening (RT) in diabetic macular edema (DME) within a clinical trial. Methods: OCT, FP and best-corrected visual acuity (VA) measurements were obtained in both eyes of 263 participants in a trial comparing two photocoagulation techniques for DME. Correlation coefficients (r) were calculated comparing RT measured by OCT, RT estimated from FP, and VA. Principal variables were centraler subfield retinal thickness (CSRT) obtained from the OCT fast macular map and DME severity assessed by a reading center using a 7-step ...
