Codes and Frequencies
For all sample adults in 2002, 2008 and 2016, and for sample adults in 1999 and 2003 who were ever told by a doctor or other health professional that they had diabetes (other than during pregnancy) (DIABETICEV), DIAEYEXAMO reports responses to the question, "When was the last time you had an eye exam in which the pupils were dilated?"
Pupil dilation allows an optometrist or ophthalmologist to see the retina, optic nerve, and blood vessels at the back of the eye. Eye examinations while the pupils are dilated may reveal early signs of glaucoma or cataracts, which are more common among diabetics than among the general population. Such examinations are also needed to diagnose diabetic retinopathy, a disease in which diabetes affects the circulatory system of the retina, leading to damage to the blood vessels and, in some cases, blindness. The American Diabetes Association recommends that diabetics see an eye care professional at least once a year for a dilated eye examination.
Using IPUMS NHIS, researchers can identify persons diagnosed with some of the eye diseases likely to be uncovered during a dilated eye examination. These diseases include cataracts (CATARACTEV, CATARACTYR), glaucoma (GLAUCOMAEV, GLAUCOMAYR), and diabetic retinopathy (DIARETINEV, DIARETINYR).
Other diabetes-related questions were periodically included in the survey; see DIABETICEV for a summary of these variables currently in IPUMS NHIS.
Apart from universe changes, this variable is comparable over time. To make DIAEYEXAMO in 2002 and 2008 fully comparable with 1999 and 2003, users should use DIABETICEV to recode sample adults in 2002 who were not ever told that they had diabetes to "Not in Universe" (NIU).
