State about the blood ocular barriers of the eye?

Blood Ocular Barrier:

All vascular beds of the eye are highly permeable to lipoid soluble substances (oxygen, carbon dioxide) and to water. The transport of material occurs through endothelial pores but some transport across endothelium occurs by the process of pinocytosis. The blood ocular barriers primarily are:

a. Blood retinal barrier

b. Blood aqueous barrier

The permeability of these barriers can be measured by ocular flurophotometry for which several instruments have been developed. The most commonly used method employ fluorescein and indocyanine.
