Establishing a Surgical Procedure for Rhesus Epiretinal Scaffold Implantation with HiPSC-Derived Retinal Progenitors

Figure 3

The fundus photograph and OCT scan of PLGA scaffold epiretinal fixation. (a) Photography of PLGA scaffold fixation after gas-liquid exchange in the surgery. (b) Fundus photography at one-month post-PLGA scaffold fixation after gas-liquid exchange. (c) SD-OCT photography at one month after PLGA scaffold fixation after gas-liquid exchange. (d) Photography of PLGA scaffold fixation by hydrogel in the surgery. (e) Fundus photography at one week after PLGA scaffold fixation by hydrogel. (f) Fundus photography at one month after PLGA scaffold fixation by hydrogel. (g, j, and m) Photography of PLGA scaffold fixation by retinal tacks in the surgery. (h, k, and n) Fundus photography at one month after PLGA scaffold fixation by retinal tacks. (i, l, and o) SD-OCT at one month after PLGA scaffold fixation by retinal tacks. The two sides of the scaffold were degraded, and the remaining central region was curled.
