|---|---|---|---|
| Primary | Change 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. |
| Primary | Median Change in Visual Acuity 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. |
| Primary | Distribution of Change in Visual Acuity 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. |
| Secondary | Central Subfield Thickness at 2 Years | 2 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. |
| Secondary | Mean Change in Central Subfield Thickness Baseline to 2 Years | Baseline 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. |
| Secondary | Median Change in Central Subfield Thickness Baseline to 2 Years | Baseline 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. |
| Secondary | Overall Central Subfield Thickening Decreased by >=50% Baseline to 2 Years | Baseline 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. |
| Secondary | Central Subfield Thickness < 250 Microns at 2 Years | 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. |
| Secondary | Change in Visual Acuity From Baseline to 3 Years | Baseline 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. |
| Secondary | Change in Visual Acuity From Baseline to 3 Years | Baseline 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 |
| Secondary | Distribution of Visual Acuity Change Baseline to 3 Years | Baseline 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 |
| Secondary | Central Subfield Thickness on Optical Coherence Tomography (OCT) at Three Years | 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. 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. |
| Secondary | Change in Central Subfield Thickness on OCT Baseline to 3 Years | Baseline 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. |
| Secondary | Percentage of Eyes With a Change in Central Subfield Thickness on OCT <250 Microns From Baseline to 3 Years | Baseline 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. |
