Dye was injected into the eye through the AC or IVT route. sCLNs and dCLNs were collected and measured using a fluorescence plate reader 1 h after injection. RFU, relative fluorescence unit (AC, n = 8; IVT, n = 8). Data are shown as mean s.e.m. *** P = 0.0002, AC sCLN; * P = 0.0167, IVT sCLN; *** P = 0.0009, IVT dCLN.
