IntroductionPathological high intraocular pressure (IOP) is an important risk factor for glaucoma. The lamina cribrosa (LC) area in the optic nerve head is the initial site of optic nerve injury for glaucoma. LC deformation caused by elevated IOP will compress the retinal ganglion cells (RGC) axons passing through it. thereby leading to the damage of the RGC axons. https://www.roneverhart.com/Zildjian-S-Series-Performer-Cymbal-Set-p9725/
