| blood-aqueous barrier | The anatomical mechanism that prevents exchange of materials between the chambers of the eye and the blood. The tight junctions of the nonpigmented epithelium of the ciliary body, the junctions of the iris tissues, and iris blood vessels constitute the blood-aqueous barrier. Lipid-soluble substances such as oxygen and carbon dioxide penetrate the barrier at a high rate. Sodium, larger water-soluble ions, proteins, and other large and medium-sized molecules are restricted. (12 Dec 1998) |

| benzalkonium chloride | A mixture of alkylbenzyldimethylammonium chlorides in which the alkyls are long-chain compounds (C8 to C18); a surface-active germicide for many pathogenic nonsporulating bacteria and fungi. Aqueous solutions of this agent have a low surface tension, and possess detergent, keratolytic, and emulsifying properties that aid the penetration and wetting of tissue surfaces. (05 Mar 2000) |
