Glaucoma screenings are vital diagnostic evaluations used to detect early signs of glaucoma—a group of eye diseases that damage the optic nerve and can lead to permanent vision loss. Often called the “silent thief of sight,” glaucoma typically develops without noticeable symptoms until significant damage has occurred. Routine screenings are the best way to identify the condition early and begin treatment before vision is affected. A glaucoma screening may include:
- Measurement of intraocular pressure (tonometry)
- Evaluation of the optic nerve using imaging or visual inspection
- Visual field testing to detect peripheral vision loss
- Pachymetry to measure corneal thickness
- Gonioscopy to examine the drainage angle of the eye
- Review of personal and family history of glaucoma
Did You Know…
that glaucoma is one of the leading causes of irreversible blindness worldwide—but early detection can prevent vision loss in most cases? Since symptoms often go unnoticed until damage has occurred, regular screenings are crucial, especially for adults over 40 and those with a family history of the condition.
Frequently Asked Questions
Who should get screened for glaucoma?
It is recommended for everyone to be regularly screened for glaucoma but especially anyone over age 40, particularly those with a family history of glaucoma, high eye pressure, diabetes, or certain ethnic backgrounds (such as African, Hispanic, or Asian descent). Your eye doctor will advise how often based on your risk factors.
Does a glaucoma screening hurt?
No, glaucoma screening is painless. While some tests may involve a brief puff of air or light pressure on the eye, they are quick and non-invasive.
What happens if glaucoma is detected?
If signs of glaucoma are present, your doctor may recommend additional testing and begin a treatment plan to manage the condition. This may include prescription eye drops, oral medications, laser treatment, or surgery to reduce eye pressure and prevent further damage.
