| retinol-binding protein | <molecular biology> Proteins which bind with retinol. The retinol-binding protein found in plasma has an alpha-1 mobility on electrophoresis and a molecular weight of 21,000-22,000. The protein has one binding site for retinol and is responsible for the transport of vitamin A. The retinol- protein complex (molecular weight 80,000 to 90,000) circulates in plasma in the form of a protein-protein complex with prealbumin. The retinol-binding protein found in tissue has a molecular weight of 14,000 and carries retinol as a non-covalently-bound ligand. (03 Jul 1999) |
| retinopapillitis | Inflammation of the retina extending to the optic disk. (05 Mar 2000) |
| retinopapillitis of premature infants | <ophthalmology, paediatrics> A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterised by vascular dilatation, proliferation, and tortuosity, oedema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (03 Jul 1999) |
