Immunosuppressive factors in porcine vitreous body
Current Eye Research, 1991High molecular (designated Sv, greater than 3K) and low molecular (designated Sv, less than 3K) fractions were prepared by filtration of porcine vitreous extracts through a membrane filter with a molecular weight cut-off of 3,000 daltons. Both fractions inhibited mitogen-stimulated proliferation of lymphocytes from rat spleen, as determined by [3H ...

Dynamic viscoelasticity of bovine vitreous body
Biorheology, 1984The dynamic mechanical property of the vitreous body was studied as functions of frequency and temperature. The data at different temperatures were found to be superposable onto a single set of master relaxation curves. It was found that the shape of the composite master relaxation curves of the vitreous body resembles that of the network polymer ...

Journal francais d'ophtalmologie, 2012
The most important age-related changes in the vitreous are progressive liquefaction and posterior vitreous detachment (PVD). Optical coherence tomography enables better in vivo visualization of the vitreoretinal interface and has improved our understanding of the process of PVD, but knowledge of the biomicroscopic aspects of these vitreous anatomical ...

Archives of Ophthalmology, 1982
Ultrastructural studies were performed on five cases of asteroid hyalosis of the human vitreous. The large asteroid bodies were composed if intertwined ribbons of multilaminar membranes with a 6-nm periodicity characteristic of complex lipids, especially phospholipids, lying in a homogeneous background matrix. Clumps of dense material were interspersed

Evaluation of Vitreous Body Integrity in Retinitis Pigmentosa by Vitreous Fluorophotometry
Archives of Ophthalmology, 1987We performed vitreous fluorophotometry on 23 eyes of 15 normal individuals and on 29 eyes of 15 patients with retinitis pigmentosa one hour after the systemic administration of sodium fluorescein. The concentration gradient of fluorescein in the posterior vitreous was evaluated from the results of the testing.

Rheology of the vitreous body. Part I: Viscoelasticity of human vitreous
Biorheology, 1992The rheological properties of the vitreous body of the eye are believed to be a function of composition and to differ among species, as well as to vary regionally within the vitreous. These properties are essential to the mechanical functioning of the eye.

LOW‐TEMPERATURE VITREOUS BODIES*
Journal of the American Ceramic Society, 1942A bstract The properties of a series of low‐temperature bodies predominately comprised of clays and nepheline syenite are described. These bodies have a higher alumina content than the usual typical pottery bodies because of the high alumina content of nepheline syenite and ...

FIBROUS COMPONENTS OF THE VITREOUS BODY
Archives of Ophthalmology, 1952THE STRUCTURE of the vitreous body is an old problem which has stimulated the attention of anatomists and ophthalmologists from the earliest time. In spite of the large amount of research work done on the subject, our knowledge of the vitreous structure is still limited.

Therapeutische Umschau. Revue therapeutique, 1990
A variety of pathological changes of the vitreous endanger the function of the retina and are therefore reason for removement of the vitreous body. The most important technique is the pars plana vitrectomy, which allows to perform the surgical manoeuvre on the stabilized eye.
