The Influence of Brightness on Functional Assessment by mfERG: A Study on Scaffolds Used in Retinal Cell Transplantation in Pigs

Figure 4

Micrograph of Hematoxylin- and Eosin-stained porcine retina after subretinally transplanting blue PLGA membrane (B). The membrane is degrading in a spongiform manner disrupting and partly destroying the outer retina. The disruption seems to vary, but no photoreceptor segments are preserved. The outer nuclear layer is relatively well preserved in a few places but generally flattened and disorganized or missing. The inner nuclear layer is relatively intact. No sign of severe inflammation in retina or choroid. Retina adjacent to the membrane appears intact. Vitreous body is indicated by “A” and sclera by “C”.
