Y cells in the cat retina are more tolerant than X cells to brief elevation of IOP.


The responses of X and Y type retinal ganglion cells were extracellularly recorded from the cat optic chiasm or tract before and during brief intraocular pressure (IOP) elevation. The responses of both X and Y cells to stimulus flashes decreased monotonically with increase of IOP. Y cells had significantly higher tolerance to IOP than did X cells. This… (More)
