Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With Vitreous Cell Count of 0 [ Time Frame: Week 4 ]
    The study eye was dilated and the investigator used an instrument to count the number of visible cells in the vitreous, the jelly-like fluid that fills the back of the eye, using the following scale: 0 (no cells) best, +1 (1-10 cells), +2 (11-30 cells), +3 (31-50 cells) and +4 (>50 cells) worst.
