Excitatory synaptic transmission in the mammalian CNS and retina is mainly mediated through L-glutamate. The effect of MK-801, a non-competitive antagonist of the NMDA subtype of glutamate receptor was studied on rat retinal ganglion cells in hypertensive eyes. MK-801 was administered intraperitoneally to the first group, 1 day before the increase, and in the second group, 2 days after the intraocular pressure (IOP) elevation. Phosphate-buffered saline was administered to the control group. Animals were sacrifice 2 and 4 weeks post-IOP increase. The retinal ganglion cells were counted and compared between control (right) and experimental (left) eyes. The data presented here suggests that MK-801 has neuroprotective properties.
