How is glaucoma diagnosed?

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.

Eye exams: Glaucoma is the irreversible loss of peripheral vision, diagnosed by a visual field and examination of the optic nerve and nerve fibers.. Glaucoma is classified by the angle formed near the root of the iris-- open or closed angle glaucoma, which are treated differently. Some forms of glaucoma have normal pressure and may be associated with sleep apnea, migraines, vasospasm or decreased blood flow.

Eye exam: Through a combination of tests including structural (disc photo, optical coherence tomography) and visual function (visual field) that demonstrates progressive damage to the optic nerve over time. Typically, measuring intraocular pressure is involved since it is our main treatable risk factor for worsening disease.

Eye examination : A comprehensive eye examination including a dilated funduscopic examination is essential to diagnosing glaucoma. Additional testing thereafter, if indicated, would also be performed. Many people diagnosed with glaucoma have no symptoms. A positive family history, traumatic eye injury, steroid medication use, inflammatory eye disease, congenital abnormalities, aging are among some instigators.
