A recent study concluded that people with myopia may have twofold to threefold increased risk of glaucoma compared with that of nonmyopic subjects. Nearly 1/3 of all U.S. residents are nearsighted. The study  found that people with higher myopia had a higher risk of glaucoma. It is therefore recommended that nearsighted people, even below age 40, should also have annual eye exams.

The study is not conclusive enough. It shows only that there may be a relationship between myopia and glaucoma, but not how myopia might lead to glaucoma. it is still safe practice for myopic patients to be aware that they may have a higher risk of glaucoma and have regular eye checkup before getting into 50.
