The vitreous after C3F8 gas instillation: Long-term histologic findings after spontaneous reabsorption of the gas in rabbit eyes

Perfluoropropane gas (C₃F₈) was injected intravitreally into rabbit eyes to displace the vitreous. Histologic examination by light and scanning electron microscopy revealed the vitreous material slowly expanded up to a nearly normal configuration during a follow-up of 6 months. Neither posterior vitreous detachment nor liquefaction of the vitreous could be observed.Presented at the XVth Meeting of the Club Jules Gonin, Copenhagen, 10–15 August 1986
