Retina is a part of the central nervous system (CNS) responsible for visual perception and processing. The retina is a complex organ and, like the CNS, it is also an immune privilege site, which has a blood retinal barrier (BRB) - the inner BRB formed by tight junctions of the endothelium and the outer BRB form by the retinal pigment epithelium (RPE). Retinal capillaries are covered by pericytes at a ratio of 1:1 with endothelial cell, which is the highest pericyte coverage in the entire vascular system. Retinal neurons are arranged in three distinctive layers - the photoreceptor layer or outer nuclear layer (ONL), which anchors at RPE, the bipolar layer or inner nucler layer (INL), and the ganglion cell layer (GCL).
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
