Structure of the Vitreous

Ox Vitreous Humour. 1. The Residual Protein

“…The insoluble residue may be separated from the soluble constituents by suspending the humour in saline and allowing the soluble substances to diffuse out into the surrounding fluid. Friedenwald and Stiehler (1935) found that the vitreous humour retained its form during prolonged washing in saline and that when it was finally filtered, the filtrate contained no organic material. We found that if an ox vitreous humour were left in the ice chest in saline 322 OX VITREOUS HUMOUR which was changed every few days, all detectable protein and hyaluronic acid had diffused out of the humour within 8-12 weeks.…”

Protein Studies on the Human Vitreous Body

“…Through the ordinary microscope fresh vitreous body demonstrates no structural elements. On the other hand, investigations with the ultramicroscope (Friedenwald and Stiehler, 1935), darkfield microscope, and phase-contrast microscope (Redslob, 1932;Matoltsy and others, 1951;Grignolo, 1952) have not led to any single conclusion, but have given rise to the present view of the vitreous body as a gel, permeated by a net of submicroscopic fibrils.…”

Effects of Biological Stimuli on the Viscosity of the Vitreous

“…not yet completely clear, although a few reports are available (Friedenwald & Stiehler 1935;Von Sallmann 1941;Balazs 1961;Bettelheim & Wang 1976). Its physicochemical properties in pathologic conditions are especially unknown.…”
