An extract of the vitreous body, inhibited the growth of new blood vessels induced by tumors in the rabbit cornea. This extract was delivered by an inert, continuously releasing polymer. The average vessel growth rate in the region surrounding the polymer was 32% less in corneas containing the inhibitory substance than in control corneas.
