Vitreous Substitution With Gases

Archives of Ophthalmology, 1975
The effects of vitreous substitution with air, a sulfur hexafluoride-air mixture, an octafluorocyclobutane-air mixture, and physiological saline were compared in owl monkeys. Each gas caused an increase in ocular vascular permeability greater than that caused by saline, as measured by vitreous inflow of serum protein labeled with iodine I 131 and ...

Biocompatibility of Polyvinylalcohol Gel as a Vitreous Substitute

Current Eye Research, 2006
Polyvinylalcohol (PVA) hydrogel cross-linked by gamma irradiation was assessed as a possible vitreous substitute. From a series of experiments, rise of intraocular pressure and inflammatory changes in the vitreous cavity after operation were observed in some cases. Crab-eating macaques were used for this experiment. PVA gels were injected into vitreous

VITREOUS SUBSTITUTE

Retina, 1984
We studied a synthetic hydrogel, PHEA [poly(2-hydroxyethyl acrylate)], experimentally. The material is transparent, autoclavable , highly viscous, nonabsorbable, easily injectable, cohesive, and does not fragment on passage through small-gauge needles.

Vitreous Substitutes

Vitreous substitutes are required in numerous vitreoretinal surgical procedures, including retinal detachment repair. Current vitreous substitutes – namely gases and oils – are suboptimal, inconvenient and inefficient for patient recovery. Herein we examine polymeric hydrogels derived from synthetic or natural sources as alternative vitreous ...

Polygeline as a Vitreous Substitute

Archives of Ophthalmology, 1966
In a previous article the experimental replacement of vitreous by polygeline (Haemaccel, Great Britain and Germany) in rabbits was discussed. 1 Since the results of these experiments were favorable, the author applied the solution clinically in cases of retinal detachment. Material and Method The commercially available 3.5% solution of polygeline was
