The effects of iodate and iodoacetate on the retinal adhesion. 1980

F S Ashburn, and A R Pilkerton, and N A Rao, and G E Marak

Sodium iodate and sodium iodoacetate were employed as biological probes to evaluate component forces contributing to the strength of retinal adhesion to the retinal pigment epithelium (RPE). Iodate treatment produced a rapid reduction in the strength of adhesion, which was complete within 1 hr without evidence of concurrent structural change. The adhesive strength reduction produced by iodoacetate required 8 to 12 hr, corresponding to the appearance of early structural changes in the photoreceptor outer segments, although delayed metabolic disturbances in the RPE might also have been involved. The study suggests that metabolic activity in the RPE may account for a portion of the strength of adhesion and that structural changes in the photoreceptor outer segments may also contribute to the forces of adhesion.

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
D000268 Adhesiveness A property of the surface of an object that makes it stick to another surface. Adhesivenesses
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
