Review
Various pharmacologic vitreolysis agents, including hyaluronidase, urea, plasmin, dispase, tissue plasminogen activator and chondroitinase have been tested. Pharmacologic vitreolysis can avoid the complications of surgery such as cataract, endophthalmitis, retinal hemorrhage, tear or detachment, and anesthesia related complications. Hyaluronan is a major macromolecule of vitreous. It is a long, unbranched polymer of repeating disaccharide (glucuronic acid beta (1,3)-N-acetylglucosamine) moieties linked by beta 1-4 bonds. Hyaluronan is covalently linked to a protein core, to form a proteoglycan. It plays a pivotal role in stabilizing the vitreous gel. Hyaluronidase cleaves glycosidic bonds of hyaluronic acid and, to a variable degree, other acid mucopolysaccharides of the connective tissue. Dissolution of the hyaluronic acid and collagen complex results in decreased viscosity of the extracellular matrix. This in turn increases the diffusion rate of erythrocytes and exudates along with phagocytes through the vitreous and facilitates red blood cell lysis and phagocytosis.

The long list of substances used by ophthalmologists for vitreous replacement can be reduced to only three for four. Their use depends upon the surgical procedure. After trauma or cataract extraction and in vitreous surgery, saline is the best substitute; it is rapidly replaced by aqueous humour and no inflammatory reaction occurs. Retinal detachment surgery requires a highly viscous material, harmless to ocular tissues, and these criteria are met by Healon H. Whenever highly viscous hyaluronic acid is available, it should be used instead of saline or air (Regnault and Brégeat, 1973). Sulphahexafluoride gas has also been used to treat these difficult cases of retinal detachment but further experience is needed before a definite conclusion can be reached.

Review
The vitreous is a part of the ophthalmological pathology not well enough known and explored. For the moment it is considered the poor relative of the examination of the posterior pole. The new technical progresses had brought though many usefull information in interpreting the vitreoretinal changes.
