Things to know about eye disease leading to blindness

This week marks World Glaucoma Day, a silent disease that leads to blindness. It has been researched that black people are at higher risk of contracting the disease, however, it tends for one to easily detect early the disease.

With the theme, ‘The world is bright, save your sight’, here are some things to know about glaucoma.

• Glaucoma is a group of eye conditions that damage the optic nerve. The optic nerve sends visual information from the eye to the brain and is vital for good vision. Damage to the optic nerve is often related to high pressure in the eye. But glaucoma can happen even with normal eye pressure.

• Glaucoma can occur at any age but is more common in older adults. It is one of the leading causes of blindness for people over the age of 60.
