Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change From Baseline in Pre-injection Intraocular Pressure for Study Eye Every 4 Weeks	Intraocular pressure (IOP) was measured using applanation tonometry Goldmann, Tonopen or approved alternative). The same method of intraocular pressure measurement was used in each participant throughout the study. For the measurement of intraocular pressure, a local anesthetic combined with fluorescein was applied topically to the eye being tested (example: one drop of oxybuprocain plus fluorescein). In the below table, pre-injection intraocular pressure for study eye was reported.	Baseline, Weeks 4, 8, 12, 16, 24, 32, 40, 48, 52
Other	Change From Baseline in Systolic Blood Pressure at Week 52	Systolic blood pressure was measured in a consistent and standardized way according to locally established practice.	Baseline, Week 52
Other	Change From Baseline in Diastolic Blood Pressure at Week 52	Diastolic blood pressure was measured in a consistent and standardized way according to locally established practice.	Baseline, Week 52
Other	Change From Baseline in Heart Rate at Week 52	Heart rate was measured in a consistent and standardized way according to locally established practice.	Baseline, Week 52
Other	Change From Baseline in Body Temperature at Week 52	Temperature was measured in a consistent and standardized way according to locally established practice.	Baseline, Week 52
Primary	Change From Baseline to Week 52 in NEI VFQ-25 Total Score	National eye institute 25-item visual function questionnaire (NEI VFQ-25) is a condition-specific measure which was designed to capture the specific impact of vision loss on health-related quality of life (HRQoL). The calculation for NEI VFQ-25 sub-scale scores and total score was performed according to the "NEI VFQ-25 Scoring Algorithm - August 2000". The NEI VFQ-25 consists of a base set of 25 vision-targeted questions representing 11 vision-related constructs, plus an additional single-item general health rating question. All items are scored so that a high score represents better functioning. Each item is then converted to a 0 to 100 scale so that the lowest and highest possible scores are set at 0 and 100 points, respectively. In this format scores represent the achieved percentage of the total possible score, e.g. a score of 50 represents 50% of the highest possible score.	Baseline, Week 52
Secondary	Change From Baseline to Week 52 in the NEI VFQ 25 Near Activities Subscale	NEI VFQ-25 is a condition-specific measure which was designed to capture the specific impact of vision loss on HRQoL. The calculation for NEI VFQ-25 sub-scale scores and total score was performed according to the "NEI VFQ-25 Scoring Algorithm - August 2000". Items within each sub-scale are averaged together to create the 12 sub-scale Scores. Items that are left blank (missing data) are not taken into account when calculating the scale scores. Sub-scales with at least one item answered can be used to generate a sub-scale score. Hence, scores represent the average for all items in the subscale that the respondent answered.The NEI VFQ-25 near activities subscale was scored from 0-100 with a score of 0 being the worst outcome and 100 being the best outcome. Near activities are defined as reading ordinary print in newspapers, performing work or hobbies requiring near vision, or finding something on a crowded shelf.	Baseline, Week 52
Secondary	Change From Baseline to Week 52 in the NEI VFQ 25 Distant Activities Subscale	NEI VFQ-25 is a condition-specific measure which was designed to capture the specific impact of vision loss on HRQoL. The calculation for NEI VFQ-25 sub-scale scores and total score was performed according to the "NEI VFQ-25 Scoring Algorithm - August 2000". Items within each sub-scale are averaged together to create the 12 sub-scale Scores. Items that are left blank (missing data) are not taken into account when calculating the scale scores. Sub-scales with at least one item answered can be used to generate a sub-scale score. Hence, scores represent the average for all items in the subscale that the respondent answered. The NEI VFQ-25 distant activities subscale was scored from 0-100 with a score of 0 being the worst outcome and 100 being the best outcome. Distant activities are defined as activities requiring distance vision, such as recognizing faces or reading street signs.	Baseline, Week 52
Secondary	Change From Baseline to Week 52 in Best Corrected Visual Acuity (BCVA) (Early Treatment Diabetic Retinopathy Study [ETDRS] Letter Score])	Visual function was assessed using the ETDRS protocol (Early Treatment Diabetic Retinopathy Study Research Group 1985) starting at 4 meters. The values might range from 0 to 100. A higher score represents better functioning.	Baseline, Week 52
Secondary	Change From Baseline to Week 52 in Central Retinal Thickness (CRT) Measured by Optical Coherence Tomography (OCT)	Retinal and lesion characteristics were evaluated using spectral domain optical coherence tomography (OCT). For all visits where the OCT procedure was scheduled, images were captured and read by the investigator. All OCTs were electronically archived at the study sites as part of the source documentation.	Baseline, Week 52
Secondary	Proportion of Participants Progressing to Greater or Equal to (>=) 61 on the ETDRS Diabetic Retinopathy Severity Scale (DRSS) as Assessed by Fundus Photography (FP)	The ETDRS DRSS was assessed by FP according to the following scale for both eyes. The following severities are possible.; 10 = Diabetic retinopathy (DR) absent, 14 = DR questionable, 15 = DR questionable, 20 = Micro-aneurysms only, 35 = Mild Non-proliferative diabetic retinopathy (NPDR), 43 = Moderate NPDR, 47 = Moderately severe NPDR, 53 = Severe NPDR, 61 = Mild Proliferative diabetic retinopathy (PDR), 65 = Moderate PDR, 71 = High-risk PDR, 75 = High-risk PDR, 81 = Advanced PDR: fundus partially obscured, center of macula attached, 85 = Advanced PDR: posterior fundus obscured, or center of macula detached, 90 = cannot grade, even sufficiently for level 81 or 85.	Baseline, Week 52
