GFP expression in monkey retina. Montages of photographs taken in vivo of monkey retinas 1 month after subretinal injection of AAV2 or AAV8 at 1010 or 1011 genome copy (GC) doses. Blue light was used for GFP excitation; GFP expression, green areas. Clockwise from top left: animal 18204, right eye; 18155, left eye; 18221, right eye; 18226, left eye.
