ListOutcomeTime frameDescription
PrimaryChange In Visual Acuity [Measured With Electronic-Early Treatment Diabetic Retinopathy Study (E-ETDRS)]Baseline to 2 Years.Baseline to 2 Years
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method. A positive change denotes an improvement. Best value on the scale 97, worst 0.
PrimaryMedian Change in Visual Acuity Baseline to 2 YearsBaseline to 2 Years
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method. A positive change denotes an improvement.
PrimaryDistribution of Change in Visual Acuity Baseline to 2 Yearsbaseline to 2 years
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method.
SecondaryCentral Subfield Thickness at 2 Years2 Years
Median central subfield thickness at two-years. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield.
SecondaryMean Change in Central Subfield Thickness Baseline to 2 YearsBaseline to 2 years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. The average of 2 baseline central subfield thickness measurements was used for analysis.If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield. Negative change denotes and improvement.
SecondaryMedian Change in Central Subfield Thickness Baseline to 2 YearsBaseline to 2 Years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. The average of 2 baseline central subfield thickness measurements was used for analysis.If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield. Negative change denotes an improvement.
SecondaryOverall Central Subfield Thickening Decreased by >=50% Baseline to 2 YearsBaseline to 2 Years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield.
SecondaryCentral Subfield Thickness < 250 Microns at 2 Years2 Years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield.
SecondaryChange in Visual Acuity From Baseline to 3 YearsBaseline to 3 year
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method. A positive change denotes an improvement.
SecondaryChange in Visual Acuity From Baseline to 3 YearsBaseline to 3 year
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method. A positive change denotes an improvement. Best Value on the scale=97, Worst Value=0
SecondaryDistribution of Visual Acuity Change Baseline to 3 YearsBaseline to 3 years
Change in best correct visual acuity letter score as measured by a certified tester using an electronic visual acuity testing machine based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method. A positive change denotes an improvement. Best value on the scale=97, worst=0
SecondaryCentral Subfield Thickness on Optical Coherence Tomography (OCT) at Three Years3 years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield.
SecondaryChange in Central Subfield Thickness on OCT Baseline to 3 YearsBaseline to 3 years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. The average of 2 baseline central subfield thickness measurements was used for analysis.If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield. Negative change denotes an improvement.
SecondaryPercentage of Eyes With a Change in Central Subfield Thickness on OCT <250 Microns From Baseline to 3 YearsBaseline to 3 years
Overall central subfield change from baseline. Optical coherence Tomography (OCT) images were obtained by a certified operator using the Zeiss Stratus OCT machine. The average of 2 baseline central subfield thickness measurements was used for analysis.If the automated thickness measurements were judged by the reading center to be inaccurate, center point thickness was measured manually, and this value was used to impute a value for the central subfield. Negative change denotes an improvement.
