In brief: 3 factors
Glaucoma is an optic nerve problem, usually consisting of high pressure in the eye, evidence of damage to the nerve on exam and on testing (oct or HRT test) and evidence of damage to the peripheral or 'near central' vision on a visual field test.

In brief: Glaucoma
Glaucoma is defined as damage to the anterior portion of the optic nerve from pressure in the eye.
" optic atrophy". This pressure is usually elevated above the typical pressure of the healthy human eye, but sometimes can happen with normal pressures.

In brief: Optic nerve damage
Glaucoma represents a spectrum of conditions which result in progressive damage to the optic nerve inside the eye.
Glaucoma is dangerous becuase it is often assymptomatic and can lead to blindess. See your eye doctor regularly since early diagnosis and treatment can minimize or prevent optic nerve damage and limit glaucoma-related vision loss.

In brief: Optic nerve pressure
Glaucoma is a form of optic nerve disease, where elevated pressures &/or poor circulation cause damage inside the eye leading to loss of peripheral vision and blindness if left untreated.
In most cases, lowering iop can stop progression and prevent vision loss.

Because Glaucoma is so insidious, so sneaky and so devastating, the public needs a "Lay definition" that avoids "medicalese:. So I would answer: A condition of the eye that often but not always is characterized by elevation of the eye pressure. Eventually resulting in loss of peripheral vision and blindness, by damaging the optic nerve. If allowed to progress the damage is irreversible.
