Figure 3.

Micrograph of Hematoxylin- and Eosin-stained porcine retina after subretinally transplanting white PLGA membrane (B). The membrane is degrading in a spongiform manner disrupting and partly destroying the outer retina with no preserved photoreceptor segments and a flattened, disrupted, or completely missing outer nuclear layer. The inner nuclear layer is relatively intact and there is no sign of severe inflammation in either retina or choroid. Retina adjacent to the membrane appears intact. Vitreous body is indicated by “A” and sclera by “C”.
