Secondary Outcome Measures:
  • Mean change of VA over time [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects underwent focal or grid laser [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects underwent vitrectomy [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • Mean VA over time and distribution of mean VA at each time point [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects who experience a ≥ 10 letter improvement of visual acuity in ETDRS chart from baseline over time [ Time Frame: 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects who experience a ≥ 15 letter improvement of visual acuity in ETDRS chart from baseline [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects who experience a ≥ 5 letter improvement of visual acuity in ETDRS chart from baseline [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects who experience a ≥ 0 letter improvement of visual acuity in ETDRS chart from baseline [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects exhibiting a decrease in retinal thickness at the center point by 25% and 50% using OCT [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • The mean change in NEI-VFQ 25 scores from baseline [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: No ]
  • Adverse Events, Serious Adverse Events, Laboratory events [ Time Frame: 24 and 54 weeks ] [ Designated as safety issue: Yes ]
