Blood-retinal barrier function in patients with cone or cone-rod dystrophy. 1986

G A Fishman, and A J Rhee, and N P Blair

We assessed blood-retinal barrier function by vitreous fluorophotometry in 24 patients with either cone or cone-rod dystrophy who were segregated into three subgroups. Compared with a normal population, the patients demonstrated increased vitreous fluorescence (breakdown of the blood-retinal barrier) that positively correlated with peripheral pigmentary changes and an appreciable reduction in electroretinographic scotopic b-wave amplitude. A unique subgroup of three women with supernormal electroretinographic scotopic b-wave amplitudes to a high-intensity stimulus had an abnormal increase in permeability of the blood-retinal barrier even without peripheral pigmentary fundus changes.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010539 Permeability Property of membranes and other structures to permit passage of light, heat, gases, liquids, metabolites, and mineral ions. Permeabilities
D010786 Photoreceptor Cells Specialized cells that detect and transduce light. They are classified into two types based on their light reception structure, the ciliary photoreceptors and the rhabdomeric photoreceptors with MICROVILLI. Ciliary photoreceptor cells use OPSINS that activate a PHOSPHODIESTERASE phosphodiesterase cascade. Rhabdomeric photoreceptor cells use opsins that activate a PHOSPHOLIPASE C cascade.

D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D012162 Retinal Degeneration A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION.
