【答案解析】The most effective health-promotion measure associated with glaucoma is annual intraocular pressure measurements after 40 years of age. People who are at risk for developing glaucoma, such as those with diabetes or hypertension, African Americans, and people with a family history of glaucoma, should have their intraocular pressure checked annually after 35 years of age. Glaucoma is insidious, basically asymptomatic, and must be diagnosed before the client becomes aware of any vision changes.
