The Blood-Retinal Barrier (BRB) is a situation of restricted permeability which is present between the blood and the retina. This barrier has a well defined anatomic substrate, particular permeability characteristics and appears to play a role of major importance in the pathophysiology and therapeutics of retinal disease.

THE BLOOD-RETINAL BARRIER IN BERLINʼS EDEMA
Retina, 1987The pathogenesis of Berlin's edema is uncertain; but one possible factor is breakdown of the blood-retinal barrier. The authors evaluated 10 affected patients with the use of vitreous fluorophotometry and fluorescein angiography. The aqueous humor dye concentration was elevated in the affected eye, compared with the unaffected eye.

Outward permeability of the blood-retinal barrier
Graefe's Archive for Clinical and Experimental Ophthalmology, 1992To characterize quantitatively the active transport mechanism of the blood-retinal barrier (BRB), we estimated the inward (Pin) and outward permeability (Pout) of the BRB in monkey eyes using vitreous fluorophotometry. Pin values for fluorescein (F) and fluorescein glucuronide (FG) were simulated by computer in separate experiments following ...

Proper retinal function requires the presence of a well-defined blood-retinal barrier (BRB). In many of the leading causes of medical blindness this BRB is compromised. Indeed, retinopathy of prematurity and age related macular degeneration both include production of aberrant vessels with poor barrier properties.

THE BLOOD‐RETINAL BARRIER PERMEABILITY IN DIABETIC PATIENTS
Acta Ophthalmologica, 1981By the of aid an extended corpus vitreum fluorophotometric technique, the blood‐retinal barrier permeability for fluorescein was studied in diabetologically well characterizied patients with insulin dependent diabetes mellitus. The method, which involves simultaneous determination of the fluorescein concentration in corpus vitreum and plasma, is ...

Inner Blood-Retinal Barrier Regulation in Retinopathies
2019The neural retina is protected from the blood circulation by the presence of a highly selective inner blood-retinal barrier (iBRB). The presence of sophisticated tight junctions (TJs) between the endothelial cells (ECs) of the iBRB helps mediate the very low passive permeability of the tissue, permitting entry of nutrients into the retina but excluding

The Blood-Retinal Barrier in Diabetes During Puberty
Archives of Ophthalmology, 1994To assess the alteration of the blood-retinal barrier in patients with type I diabetes during puberty.A 7-year prospective study evaluated retinal changes occurring in diabetic children during puberty. Patients between the ages of 10 and 20 years underwent annual ophthalmologic examinations that included fluorescein angiography and vitreous ...

The Inner Blood-Retinal Barrier
2013The inner blood-retinal barrier (inner BRB) is created by complex tight junctions of retinal capillary endothelial cells. Although this barrier prevents the free diffusion of substances between the circulating blood and the neural retina, the inner BRB efficiently supplies nutrients to the retina and removes endobiotics and xenobiotics from the retina ...

Shear stress modulates inner blood retinal barrier phenotype
Experimental Eye Research, 2019The vascular endothelium responds to the shear stress generated by blood flow and changes function to maintain tissue homeostasis and adapt to injury in pathological conditions. Shear stress in the retinal circulation is altered in patients with retinal vascular diseases, such as diabetic retinopathy.

Alteration of the Blood-Retinal Barrier by Dipyridamole
Archives of Ophthalmology, 1986To the Editor. —Platelet hypersensitivity and increased prostaglandin levels have been implicated in the development of diabetic retinopathy. 1 Dipyridamole is an inhibitor of thromboxane A 2 synthesis and platelet aggregation. Microangiopathy and a breakdown of the blood-retinal barrier have been correlated with fluorescein leakage into the posterior
