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.
Dr. Victor Bello

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.

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.
Dr. Ilan Cohen

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.
Dr. Michael Ham
Ophthalmology 27 years experience
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.

Dr. Cynthia Point
Specializes in Internal Medicine
Eye exams: Glaucoma is damage to the optic nerve caused by eye pressures that are too high for the particular eye. It is diagnosed by the eye doctor seeing the optic nerve having a special appearance, and then a test called a visual field test shows loss of vision in the outer part of the field. That is why we all should get eye exams starting at about 40 years of age.

Many types: Typically the types are divided into "causes" or the "drain status" thus primary glaucoma vs. Secondary glaucoma (caused by something that is affecting the drain of the eye) or open angle vs. Closed angle glaucoma basically glaucoma can happen at various pressures that is damaging to the individual patient, so there is no pressure cutoff.
