The primary outcome will be an assessment of post-injection intraocular toxicity related events including increased inflammation, increased intraocular pressure, significant decreases in BCVA, cataract formation, retinal detachment, and intraocular hemorrhage. The secondary outcomes will be an improvement of 15 letters in best-corrected visual acuity (BCVA, ETDRS) from baseline to year 3, and decreases in retinal thickening and area of leakage.
