Abstract

The subject of the blood-retinal barrier (BRB) is important in understanding the pathology of various retinal diseases as well as in their treatment. There is a voluminous literature on the BRB and its derangement. The retina is transparent so that the light travels unhindered to the photoreceptors. Therefore, for proper visual function of the retina, as well as for physiological integrity of the retinal vessels and retinal homeostasis, the presence of an efficient BRB is essential. To do that, the BRB regulates movement of fluids and molecules between the blood and the retina. Also for drug delivery to the retina, the presence of a BRB becomes an important consideration [1].
