What is glaucoma?

Dr. Sarab Alfata
Family Medicine 21 years experience
Eye disease: Eye disorder in which the optic nerve suffers damage, permanently damaging vision in the affected eye(s) and progressing to complete blindness if untreated. It associates with increased pressure of the fluid in the eye
Dr. Robert Chang
Specializes in Ophthalmology
Eye disease: There are many types of glaucoma, but the final common pathway is the progressive loss of ganglion cells (faster than age-related loss) and resultant increase in "cupping" of the optic nerve, leading to loss of vision. The cause of glaucoma can be multifactorial and is typically divided into mechanical and vascular issues.
Dr. Richard Bensinger
Ophthalmology 53 years experience
Impaired eye fluid: Glaucoma is a condition in the inside of the eye, in which the fluid (aqueous humor) cannot get out at a low enough pressure to prevent the pressure from causing loss of the nerves and blood vessels at the back of the eye which causes vision to be lost. Measured will be eye pressure, corneal thickness, visual field, and disc structure. These are all part of the diagnosis.
Dr. Yash Khanna

Increased pressure: It is associated with increase fluid pressure in the eye and causes damage to the optic nerve in a characteristic pattern.If not treated properly it can lead to blindness.
Dr. Harold Peltan

Glaucoma: Glaucoma is a family of conditions that cause withering of the optic nerve and corresponding defects in the visual field. It may or may not be associated with increased eye pressure.
Dr. Robert Kwok
Pediatrics 34 years experience
Eye pressure problem: Glaucoma is an eye disorder that damages the eye’s optic nerve, which is the main nerve attached to the back of the eyeball. It usually happens when fluid builds up in the eyeball and increases the pressure inside the eye, thus damaging the optic nerve. Glaucoma is a cause of blindness for people over age 60. Blindness from glaucoma usually can be prevented with medical care.

What are the stages of glaucoma?

Dr. Robert Chang
Specializes in Ophthalmology
Spectrum: It can be divided into pre-perimetric disease (before anything shows up on visual field testing), and perimetry disease (once you have visual field abnormalities), and at that point glaucoma can be divided into mild, moderate, and severe based on how abnormal the field is. Usually it's end stage when central vision is also diminished.
A 30-year-old member asked:

Is there an "opposite" of glaucoma?

2 doctor answers5 doctors weighed in
Dr. Glenn Pomerance
Ophthalmology 48 years experience
In a way, yes!: If the pressure of the eye is too low, the opposite of glaucoma where it is too high, damage and loss of sight may be associated. If the pressure drops due to injury, say, then the low pressure is an effect of the loss of function rather than being the cause of the loss of function. This is called phthisis bulbi (pronounced "ty-sis bulb-eye". Hopefully i made the difference clear!

Many things: Age, genetics, cup:disc ratio (how optic nerve looks), eye pressure, thickness of the cornea (called pachymetry), ass'd medications (chronic steroids most common), other eye diseases, history of trauma.
