what causes glaucoma?

Mostly unknown: A few cases of glaucoma occur due to trauma, inherited problems and anatomical underpinnings. The majority - 'open angle glaucoma'- is largely age related with no known cause.
Dr. Michael Ham
Ophthalmology 27 years experience
Genetics and age: The two largest factors contributing to the development of glaucoma are age and genetics. Other than that, trauma, steroid usage, anatomical conditions (narrow angles, pseudoexfoliation syndrome, pigmentary dispersion syndrome of the iris, cataracts), prior surgery, can all cause glaucoma. The underlying cause of glaucoma is to much pressure on the optic nerve causing it to die off.
Dr. George Yang
Ophthalmology 27 years experience
Pressure imbalance: Ultimately, glaucoma is a pressure imbalance where the pressure inside the eye is too high for the eye, leading to nerve damage. Pressure is an equilibrium of fluid being made in the eye and fluid flowing out of the eye. Treatments for glaucoma either decrease fluid production, increase fluid outflow, or increase the effective space within the eye.
Dr. Douglas Liva
Ophthalmology 40 years experience
Usually elevated IOP: Glaucoma is an optic neuropathy that is associated with several risk factors including elevated intraocular pressure, a thin cornea, family history, increased optic nerve cupping, myopia and being African American . It is not always associated with elevated intraocular pressure. Normal tension glaucoma results in similar optic nerve pathology with normal eye pressure. Treatment is lowering the IOP

Dr. Richard Bensinger
Ophthalmology 52 years experience
Age, heredity, injur: Glaucoma has multiple causes. Most, called open angle, are age related with no actual known cause. Some glaucomas are present at birth and are related to immature anatomy or inherited issues. Others related to disturbance of the anatomy in people who are farsighted. And some are due to trauma. Other conditions also contribute. Sort yours out with your ophthalmologist.

Vision loss: Blurriness can also be caused by extremely high eye pressure and corneal edema, inflammation, side effects from medications or surgery. If your vision has become blurry you should definitely consult with your eye physician asap. It may be reversible.

Coffee and glaucoma : Presumably your concern is the risk of caffeine causing glaucoma. The eye pressure raising effects of caffeine have been known in the literature, the effect is small and not a usual risk factor for causing glaucoma.
Dr. Jon Fishburn
Ophthalmology 30 years experience
Provided original answer
There is a modest IOP raising effect which is not clinically significant as shown in a paper by Eve Higginbottham.

No, but ...: Angle closure glaucoma, which is rather uncommon (less than 1% in the U.S.) could occur with mid-pupil dilation; some near effort causes moderate pupil constriction. Primary open angle glaucoma is not caused by lifestyle choices or by visual effort.
