Primary Outcome Measures:
  • Complications, including those related to the intravitreal injection, and adverse events, and loss of lines of best-corrected visual acuity, slit lamp findings, lens opacification, intraocular pressure, fundus findings, and laboratory findings.

Secondary Outcome Measures:
  • Stabilization of visual acuity (prevention of loss of three or more lines on the ETDRS chart), stabilization of lesion size, lack of leakage of lesion, or decrease in subretinal fluid
