Abstract
Foscarnet sodium is an antiviral drug for the treatment of CMV retinitis, currently in the form of twice-weekly intravitreal injection. Here we developed foscarnet calcium microcrystals as the drug depot, and using the rabbit model we demonstrated that the injected microcrystals maintained a therapeutically relevant drug concentration in the vitreous for more than 3 months.
