|
increased intraocular pressure results in damage to the retina and optic nerve with loss of vision
|
Detailed explanation-1: -If that system is blocked or isn’t functioning well, the pressure inside the eye (intraocular pressure) builds, which in turn damages the optic nerve. With the most common type of glaucoma, this results in gradual vision loss. Glaucoma is a group of eye conditions that damage the optic nerve.
Detailed explanation-2: -Ocular hypertension, defined as a chronic, mild elevation of IOP, can lead to slowly progressive changes in visual function and optic nerve appearance.
Detailed explanation-3: -Most cases are caused by a build-up of pressure in the eye when fluid is unable to drain properly. This increase in pressure then damages the nerve that connects the eye to the brain (optic nerve).
Detailed explanation-4: -Elevated intraocular pressure (IOP) is the greatest known risk factor for glaucoma, 1 the second most common cause of blindness worldwide. A rise in IOP leads to an elevated pressure gradient across the lamina cribrosa, predisposing the retinal ganglion cell (RGC) axons to damage at this site.
Detailed explanation-5: -Glaucoma is associated with characteristic damage to the optic nerve and patterns of visual field loss which principally involves the loss of retinal ganglion cells (RGCs).
