Etymology
Greek glaukoma named a cataract or clouding of the lens. The English term was first used before cataracts and glaucoma were distinguished, so its older meaning was broader than the modern diagnosis.
In context
Glaucoma is most common in African Americans over the age of 40; people over 60, and in people with a family history of glaucoma.
