How Does Glaucoma Cause Vision Loss?

Glaucoma is one of the leading causes of blindness in the world, and 50% of people who have it don’t even know they do.

SICK is a new series that looks at how diseases actually work inside our body. We'll be visiting medical centers and talking to top researchers and doctors to uncover the mysteries of viruses, bacteria, fungi and our own immune system. Come back every Tuesday for a new episode and let us know in the comments which diseases you think we should cover next.
