The term glaucoma encompasses a group of disorders that cause damage to the optic nerve, leading to vision loss or blindness if left untreated.
I think "celebrity glaucoma" is an outstanding turn of a phrase, Rich.
It lowers intraocular pressure in glaucoma patients, decreases spasticity and other neurologic symptoms in multiple sclerosis, and there is evidence that it is useful in a variety of additional medical conditions.

Pigment dispersion syndrome, as you say, is a condition that can lead to glaucoma, which is optic nerve damage from elevated pressure within the eye.
It is convenient to start with the conception that glaucoma is increased tension of the eyeball, plus the causes and effects of such increase; although a broad survey of the facts may reveal a clinical entity to be called glaucoma, without increased tension constantly or necessarily present, and cases of increased intra-ocular tension not to be classed as glaucoma.
When these two factors coexist in their varying combinations, pathological increase of pressure results -- in short, glaucoma.
