Removal of the natural vitreous body from the eye and its substitution with a tamponade agent may be necessary in cases of complicated retinal detachment. Many materials have been variously proposed and tested over the years in an attempt to find an ideal vitreous substitute. This review highlights the evolution of research in the field of vitreous replacement and chronicles the main advances t...

Ten eyes of nine patients were treated for very disturbing vitreous floaters with the technique of Nd-YAG laser vitreolysis. The Scanning Laser Ophthalmoscope (SLO) was used to objectivate the position, the size and the motility of the vitreous floaters with respect to the patient's visual axis, which can be precisely located with the SLO. With this technique it was possible to define more prec...

PURPOSE The aim of this study was the assessment of vitreous humor as a potential DNA for forensic human postmortem identification. MATERIAL AND METHODS Vitreous humor samples were collected using two alternative approaches from 25 corpses of either sex during autopsies. DNA was extracted by standard organic method. Recovered DNA was quantitiated fluorometrically. AmpFlSTR SGM Plus kit and AB...

AIM The aim of the paper was to present the efficacy and indications for application of conventional surgical treatment of retinal detachment by using external implants, that is,application of encircling band and buckle. MATERIAL AND METHOD This study comprised patients from the University Eye Clinic in Skopje. A total of 33 patients were diagnosed and surgically treated in the period between...

Vitreoretinal surgery has advanced in numerous directions during recent years. The removal of the vitreous body is one of the main characteristics of this surgical procedure. Several molecules have been tested in the past to fill the vitreous cavity and to mimic its functions. We here review the currently available vitreous substitutes, focusing on their molecular properties and functions, toge...

Since iLlijrner (l), the proteins of the vitreous body have been generally classified as residual and soluble proteins. The former includes those elements of the gel which can be collected as a residue after filtration or as a sediment after high speed centrifugation (more than 50,000 X g). The latter refers to the proteins in the liquid vitreous, the viscous fluid remaining after removal of th...

V itreous is a remarkable structure. It is 98% water, but owing to the 2% structural macromolecules, vitreous maintains an exquisite gel structure. Those structural macromolecules are hyaluronan, which is a glycosaminoglycan of repeating disaccharide units, and collagen. Because hyaluronan is very hydrophilic and absorbs water, where it goes, water follows. Hylauronan is also organized within a...
