If raised IOP is not the only determinant of glaucoma, what are the other factors? JFW | T@lk 16:59, 15 Apr 2005 (UTC)

Glaucoma is now generally defined as a progressive optic neuropathy characterized by damage to the optic nerve and visual field loss. This definition is more widely accepted given that someone can have have elevated IOPs without neuropathy or neuropathy without elevated IOPs. --AED 17:14, 15 Apr 2005 (UTC)

So what is the neuropathy due to, if not pathologically raised IOP? And why can raised IOP without neuropathy not be termed "glaucoma"? JFW | T@lk 10:03, 17 Apr 2005 (UTC)

1) We don't know what causes glaucomatous neuropathy. 2)Raised IOP without neuropathy is not termed "glaucoma" a) because "glaucoma" implies damage to the OHN, b) because an elevated IOP without ONH damage is simply an elevated IOP, and c) because an elevated IOP (usually > 21mmgHg) is termed "ocular hypertension". --AED 04:07, 18 Apr 2005 (UTC)

I've observed on some occasions that staring directly into certain light sources (specifically, a fluorescent tube at close range) can cause what feels like a surge in pressure within the eyes, most unpleasant. Is there anything to support that some forms of eye stimulation can (briefly) affect intraocular pressure? --Iskunk 08:49, 23 July 2006 (UTC)
