Abstract
Three weeks after a single intravitreal injection of ethylcholine aziridinium ion (AF64A), there was a significant depletion of retinal acetylcholine (ACh) content. The depletion was accompanied by an increase of [ 3H]quinuclidinyl benzilate binding sites and a greater than control conversion of myo-[ 3H]inositol to inositol monophosphate following incubation with ACh. These changes are consistent with receptor supersensitivity due to AF64A-induced denervation.
