Description
GLAUCTESTYRS reports the amount of time since the last glaucoma test. Interviewers asked, "About how long has it been since [you/person] had a test for glaucoma - (this is) sometimes referred to as an eye pressure test?"
According to the 1973 and 1982 Field Representative's Manuals, this question was part of a survey section dealing with the use of preventive care services. For the preventive care supplement, in both 1973 and 1982, interviewers were directed to interview persons directly rather than relying on proxy reporting; see CXRAYRS for more information.

Other variables in the 1973 and 1982 surveys that report time since specific types of preventive care include: CXRAYRS (for chest x-ray), EKGYRS (for electrocardiogram), and EYEXAMYRS (for vision test).
For 1973, responses to the question on years since last glaucoma test were topcoded at 10+ years in the NHIS public use files created by the National Center for Health Statistics. Single year responses up to 40+ years for years since last glaucoma test are available for 1982, in GLAUTESTYREX.
Information on whether individuals were ever diagnosed as having glaucoma is available in 1999 and 2002 (GLAUCOMAEV). In 2002 only, a follow-up question identified those who had glaucoma in the past 12 months (GLAUCOMAYR).
