Warning Signs and Silent Progression

Glaucoma may have few early symptoms, so routine eye exams are important for detecting optic nerve damage early.
Glaucoma most often occurs in adults over 40, but it can also affect young adults, children, and infants. Many patients have few or no symptoms in the early stages.
The first sign is often loss of peripheral or side vision, which can go unnoticed until the disease is advanced. This is why complete eye exams are important every one to two years, especially for patients with risk factors.
The brain can compensate for early side vision loss, so a patient may continue reading, driving, or working without realizing that glaucoma damage has started. Objective tests are needed to detect early optic nerve and visual field changes.
If symptoms or risk factors are present, your doctor may check visual acuity, eye pressure, corneal thickness, drainage angle, optic nerve health, OCT scans, and visual fields.
