- Incidence of Serious Adverse Events. [ Time Frame: 24 mos ]Record the serious adverse events, both ocular and non-ocular to gather long-term safety data.
- Mean Changes in Visual Acuity [ Time Frame: 24 mos from study baseline ]Mean changes in visual acuity. Visual acuity is measured using standard ETDRS (Early Treatment Diabetic Retinopathy Study) charts which measure visual acuity in terms of letters( ETDRS Letters) read at a distance of 4 meters away from the chart. The ETDRS letters Score can be from 0 to 100, with 0 representing poor vision and 100 representing best vision.
- Mean Change in Retinal Thickness [ Time Frame: 24 mos from study baseline ]Mean change in retinal thickness as measured by OCT (Optical Coherence Tomography).
