Indications
DISCOVISC Ophthalmic Viscosurgical Device Injection is used for:
CHONDROITIN SULFATE
For the treatment of osteoarthritis
HYALURONIC ACID
Used to treat knee pain in patients with joint inflammation (osteoarthritis). It is usually used in patients who have not responded to other treatments such as acetaminophen, exercise, or physical therapy. Hyaluronic acid may also be used in plastic surgery to reduce wrinkles on the face or as a filler in other parts of the body. May be used in ophthalmology to assist in the extraction of cataracts, the implantation of intraocular lenses, corneal transplants, glaucoma filtration, retinal attachment and in the treatment of dry eyes. Finally, hyaluronic acid is also used to coat the bladder lining in treating interstitial cystitis

Mechanism of Action
HYALURONIC ACID
Hyaluronic acid functions as a tissue lubricant and is thought to play an important role in modulating the interactions between adjacent tissues. Hyaluronic acid is a polysaccharide which is distributed widely in the extracellular matrix of connective tissue in man. It forms a viscoelastic solution in water which makes it suitable for aqueous and vitreous humor in ophthalmic surgery. Mechanical protection for tissues (iris, retina) and cell layers (corneal, endothelium, and epithelium) are provided by the high viscosity of the solution. Elasticity of the solution assists in absorbing mechanical stress and providing a protective buffer for tissues. This viscoelasticity enables maintenance of a deep chamber during surgical manipulation since the solution does not flow out of the open anterior chamber. In facilitating wound healing, it is thought that it acts as a protective transport vehicle, taking peptide growth factors and other structural proteins to a site of action. It is then enzymatically degraded and active proteins are released to promote tissue repair. Hyaluronic acid is being used intra-articularly to treat osteoarthritis. Cell receptors that have been identified for hyaluronic acid fall into three main groups: cd44, receptor for hyaluronan-mediated motility (rhamm) and intracellular adhesion molecule-1 (icam-1). Cd44 mediates cell interaction with hyaluronic acid and the binding of the two functions as an important part in various physiologic events, such as cell aggregation, migration, proliferation and activation; cell-cell and cell-substrate adhesion; endocytosis of hyaluronic acid, which leads to hyaluronic acid catabolism in macrophages; and assembly of petircellular matrices from ha and proteoglycan. Cd44 has two important roles in skin, regulation of keratinocyte proliferation in response to extracellular stimuli and the maintenance of local hyaluronic acid homeostasis. Icam-1 is known mainly as a metabolic cell surface receptor for hyaluronic acid, and this protein may be responsible mainly for the clearance of hyaluronic acid from lymph and blood plasma, which accounts for perhaps most of its whole-body turnover. Ligand binding of this receptor, thus, triggers a highly coordinated cascade of events that includes the formation of an endocytotic vesicle, its fusion with primary lysosomes, enzymatic digestion to monosaccharides, active transmembrane transport of these sugars to cell sap, phosphorylation of glcnac and enzymatic deacetylation. Icam-1 may also serve as a cell adhesion molecule, and the binding of hyaluronic acid to icam-1 may contribute to the control of icam-1-mediated inflammatory activation
