What are the differences between blood retinal barrier and blood aqueous barrier?

Blood Retinal Barrier:

Blood retinal barrier is present in retina. In retina there are two tight junctions, outer blood retinal barrier is present between retinal pigment epithelial cells and inner blood retinal barrier is present between endothelial cells of retinal capillaries. Normally a defect of blood retinal barrier exists at the level of optic disc where the water soluble substance may enter the optic disc by diffusion from extra vascular space of thechoroid.

Blood Aqueous Barrier:

Blood aqueous barrier is present in anterior segment of the eye. There are two tight junctions one between the endothelial cells of iris capillaries and the other at the level of non-pigment layer of ciliary epithelium.
