My question is regarding the biological nature of the separation between the vitreous humour and aqueous humour of the human (or mammal) eye. What connects the two in terms of the passive transport of proteins between the two? Is there a single membrane?
If so what is the name of this membrane and is it the only thing separating the aqueous from the vitreous? What is the anatomical difference between the aqueous and the vitreous?
Apologies, I am far from a biologist.
Specifically what sort of transport is arrow 9 in the figure below representing? And is backward transport (from the aqueous to the vitreous) possible?
Any links to papers detailing this mechanism would be highly appreciated, I can only find references to experimental readings of concentrations, but nothing about the transport process itself.
