RGC functional deficits in glaucoma are improved by galantamine. (a) Visual evoked potentials (VEP) recorded from galantamine-treated normal brains were indistinguishable from those treated with PBS or without treatment. (b) At 3 weeks after OHT surgery, galantamine administration led to marked preservation of the VEP responses (ANOVA, *P<0.001). (c) At 5 weeks after OHT surgery, both PBS-treated and galantamine-treated glaucomatous eyes showed complete obliteration of the VEP response. Daily application of Timolol drops on the cornea was sufficient to restore the VEP response in galantamine-treated eyes but not in PBS-treated eyes (ANOVA, *P<0.001)
