Glaucoma and Age-related Macular Degeneration (AMD)
Two of the most common causes of blindness in the United States
Risk factors:– AGE: especially over the age of 60– Family history– Race

Glaucoma
Glaucoma: – Fluid builds up in the
eye, so that the eye pressure rises
– This higher eye pressure can damage the optic nerve over time
