4. Glaucoma
• Glaucoma causes damage to your eye's optic
nerve and gets worse over time.
• Glaucoma is often associated with a buildup
of pressure inside the eye. Glaucoma tends
to be inherited and may not show up until
later in life.
• If damage to the optic nerve from high eye
pressure continues, glaucoma will cause
permanent loss of vision.

5. Glaucoma
The increase in the eye pressure
will damage the optic nerve

8. Glaucoma is a Blinding Disease
• Glaucoma is a leading causes of adult
blindness in the US. The national rate is
1.9% for the U.S. population age 40 and
older.
• If damage to the optic nerve from high
eye pressure continues, glaucoma will
cause permanent loss of vision.
• Without treatment, glaucoma can cause
total permanent blindness within a few
years.

9. Glaucoma Vision Loss

10. Who is at Risk?
• People over the age of 50
• People with hypertension
• People with a family history of glaucoma
• Very near-sighted people
• African-Americans
• People on corticosteroids
• Diabetics
• People who have had a serious eye injury

11. What are the Symptoms of
Glaucoma?
• Seeing halos around lights
• Vision loss
• Redness in the eye
• Eye that looks hazy
• Nausea or vomiting
• Pain in the eye
• Narrowing of vision (tunnel vision)

12. How is Glaucoma Diagnosed?
• Eye exam
• Eye pressure
• Side vision test
• Optic nerve test
• Glaucoma tests are painless and take very
little time.

15. Treatment
• Medications: eye drops
 To reduce the formation of fluid in the front
of the eye or increase its outflow.
• Laser Surgery: trabeculoplasty,
iridotomy, & cyclophotocoagulation
• Microsurgery: Trabeculectomy,
Glaucoma drainage implants (GDI), etc.

18. Summary
• Glaucoma is a very common cause of
blindness and visual impairment worldwide
• Clinical examination with visual field testing
and optic nerve imaging can identify patients
with optic nerve damage
• Early treatment, before development of
advanced optic nerve damage is crucial
• Glaucoma cannot be prevented, but if it is
diagnosed and treated early, the disease can
be controlled
