Immunohistochemical analyses of VEGF-A. Immunostaining of VEGF-A was found in two different patterns. b Controls with PPADS treatments showed a positive immunoreactivity in GCL, INL and PIS. a Controls without treatment and c, d diabetic animals showed staining in structures which may be small vessels (arrows). GCL ganglion cells layer; INL Inner nuclear layer; PIS photoreceptor inner segment; DBT diabetic; PPADS animals treated with pyridoxalphosphate-6-azophenyl-2′,4′-disulfonic acid
