- Percentage of Participants Who Had Sustained Moderate Visual Loss (SMVL) as Defined as a Visual Acuity Loss of ≥15 Letters Measured Twice During a 6-month Period [ Time Frame: Baseline through 36 months ]SMVL is defined as a ≥15-letter decrease from baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) that the participant sustained during the last 6 months of study participation (Months 30-36). Participants who discontinued the study early may have had SMVL if there was a 6-month period of ≥15 letters lost in VA ending with the last visit at which VA was assessed. ETDRS visual acuity uses an eye chart with 5 letters per line. The scores range from 0 (no letters read correctly) to 100 (all letters read correctly). Percentage of participants = (number of participants who had SMVL) / (number of participants who were randomized) * 100.
- Percentage of Participants Who Developed Center Involved or Imminently Threatened Diabetic Macular Edema (DME) [ Time Frame: Baseline through 36 months ]DME is the accumulation of extracellular fluid in the retinal tissue of the macular area, which can reduce the ability for fine visual discrimination. Percentage of participants = (number of participants who developed center involved or imminently threatened DME) / (number of participants who had no center involved or imminently threatened DME at baseline) * 100.
- Percentage of Participants Who Experienced the Development of Proliferative Diabetic Retinopathy (PDR) [ Time Frame: Baseline through 36 months ]Percentage of participants = (number of participants who experienced the development of PDR) / (number of participants who were randomized) * 100.
- Change From Baseline up to 36 Months in the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) [ Time Frame: Baseline, up to 36 months ]NEI-VFQ-25 consisted of 25 questions and was used to measure the influence of visual disability and symptoms on general health of participants. The possible total score range for the NEI-VFQ-25 was from 0 (worst possible outcome) to 100 (best possible outcome).
- Change From Baseline up to 36 Months in Mental and Physical Components of the Medical Outcomes Study 36-Item Short Form (SF-36) Health Status Questionnaire [ Time Frame: Baseline, up to 36 months ]SF-36 is a health-related survey that assesses participant's quality of life and consists of 36 questions. There are 2 component scores, mental component score (MCS) and physical component score (PCS). MCS score consisted of social functioning, vitality, mental health, and role-emotional scales. PCS score consisted of physical functioning, bodily pain, role-physical, and general health scales. Both MCS and PCS have scores ranging from 0 to 100 with higher scores indicating better mental or physical health.
