We found that BMD stimulates the production of NGF, BDNF and bFGF, all of which induce RGC survival, in Müller glial cells.24, 37 Taken together, in addition to lowering IOP, BMD may prevent glaucomatous retinal degeneration by stimulating multiple pathways including glia–neuron interactions. Here, FGF2 is linked to retinal degeneration.
