Modeling of microglia based on Iba1 marker on retinal tissue in contact with devices with graphene (a). Each different color represent a different microglial. Scale bars are 50 μm. Graph (b) is the statistical analysis of microglial count comparing retinal tissue in contact with the two types of implant and retinal tissue from non-operated eyes. Graph (c) is the comparison of microglial volume between the three conditions. ns indicates p > 0.05, * indicates p ≤ 0.05.
