Has anyone been put on medication for simply being a glaucoma suspect?

Generally not: In most cases, once testing indicates someone has glaucoma, they are no longer considered suspect and are started on treatment. However, sometimes the tests aren't conclusive, but the optic nerve appears to have glaucoma related damage. In this case, a doctor may start you on medicine, but still call you a suspect.

Yes: Based on risk analysis high risk suspects can be treated as in the ocular hypertension treatment study.
