✦ Synopsis


The concentration of cyclosporine in the vitreous after intravitreal injection of 100 micrograms of either free or liposome-bound cyclosporine was studied in albino rabbits. We found that the half-life of free cyclosporine was about 6 hours and that of liposome-bound cyclosporine was about 3 days. The finding indicates that liposome-bound cyclosporine prolongs the availability of the drug.

The retinal toxicity of intraocular liposome-bound cyclosporine was studied in albino rabbits by means of electrophysiology and histopathology. During a followup period of one month, no histopathological or electroretinographic changes were noted using concentrations of 100, 200 and 500 micrograms i

The concentration of cyclosporine in the aqueous and vitreous humors of albino rabbits was measured, using HPLC at intervals of 24, 48, 96, and 192 hours after subconjunctival injections of 2.5 mg of free or liposome-bound cyclosporine. The aqueous concentration was reasonably high in both groups un
