In 2017, the prevalence of diagnosed diabetes increased from 13.2% among adults aged 45–64 to 20.1% among those aged 65–74 and 19.8% among those aged 75 and over (1). Compared with adults without diabetes, adults with diabetes are more likely to develop eye disorders and vision loss from eye disorders (2,3). Moreover, duration of diabetes is a risk factor for the progression of visual problems (3,4). This report compares the age-adjusted percentages of adults aged 45 and over with diagnosed diabetes who were told by a doctor or other health professional that they had cataracts, diabetic retinopathy, glaucoma, or macular degeneration and vision loss due to these disorders, by years since their diabetes diagnosis.Keywords: cataracts, glaucoma, diabetic retinopathy, National Health Interview SurveyCataracts and vision loss due to cataracts increased with increasing duration since diabetes diagnosis among adults aged 45 and over with diagnosed diabetes.* Among adults aged 45 and over with diagnosed diabetes, 32.2% had cataracts, and 9.2% had vision loss due to cataracts (Figure 1).* Adults aged 45 and over who have had diagnosed diabetes for 10 years or more were more likely to have cataracts (35.9%) than those having diagnosed diabetes for less than 10 years (27.2%).* Adults who have had diagnosed diabetes for 10 years or more were more likely to have vision loss due to cataracts (10.4%) than those having diagnosed diabetes for less than 10 years (7.3%).Figure 1.

Access data table for Figure 4.SOURCE: NCHS, National Health Interview Survey, 2016–2017.SummaryThis report examined four eye disorders among adults aged 45 and over with diagnosed diabetes and found that the most commonly reported eye disorder affecting this population was cataracts, followed by diabetic retinopathy, glaucoma, and macular degeneration. Similarly, vision loss among this population was most commonly due to cataracts, followed by diabetic retinopathy, macular degeneration, and glaucoma. Adults who have had diagnosed diabetes for 10 years or more were more likely to report each of these eye disorders. In addition, adults who have had diagnosed diabetes for 10 years or more were more likely to report vision loss due to cataracts, diabetic retinopathy, and macular degeneration than those having diagnosed diabetes for less than 10 years.Vision loss is a severe condition that often has a negative impact on a person’s quality of life and mental health (5). Because eye disorders are a frequent complication from diabetes, the American Diabetes Association recommends that patients with type 1 diabetes have an initial dilated and comprehensive eye examination by an ophthalmologist or optometrist within 5 years after receiving a diabetes diagnosis (4). Adults with type 2 diabetes are recommended to have this initial examination at the time of their diagnosis. The frequency of subsequent examinations depends on the patient’s glycemic control and evidence of diabetic retinopathy (4).DefinitionsCataracts: Based on a positive response to the survey question, “Have you ever been told by a doctor or other health professional that you had cataracts?” A follow-up question asked if the respondent had ever lost any vision because of cataracts.Diabetic retinopathy: Based on a positive response to the survey question, “Have you ever been told by a doctor or other health professional that you had diabetic retinopathy?” A follow-up question asked if the respondent had ever lost any vision because of diabetic retinopathy.Diagnosed diabetes: Based on a positive response to the survey question, “Have you ever been told by a doctor or other health professional that you have diabetes or sugar diabetes?” Women were asked to exclude diagnosis received only during pregnancy.Glaucoma: Based on a positive response to the survey question, “Have you ever been told by a doctor or other health professional that you had glaucoma?” A follow-up question asked if the respondent had ever lost any vision because of glaucoma.Macular degeneration: Based on a positive response to the survey question, “Have you ever been told by a doctor or other health professional that you had macular degeneration?” A follow-up question asked if the respondent had ever lost any vision because of macular degeneration.Years since diabetes diagnosis: Defined as the respondent’s age at interview minus the age given to the question, “How old were you when a doctor first told you that you had diabetes or sugar diabetes?” Age at diabetes was unknown for 2.3% of sample adults in the analysis.Data source and methodsData from the National Health Interview Survey (NHIS) were used for this analysis. NHIS is a multipurpose health survey conducted continuously throughout the year by the National Center for Health Statistics (NCHS). Interviews are conducted in person in respondents’ homes, but follow-ups to complete interviews may be conducted over the telephone. NHIS consists of four main components: the Household, the Family, the Sample Adult, and the Sample Child. These components include both a core set of questions that remain relatively unchanged from year to year as well as supplemental questions that are not asked every year. During 2016‒2017, NHIS supplementary questions included expanded content on vision. Data for this analysis came from the 2016–2017 NHIS Sample Adult core component and the supplementary questions on vision. For more information about NHIS, including the questionnaire and annual supplements, visit the NHIS website.All analyses used weights to produce national estimates. Estimates on eye disorders in this report are nationally representative of the civilian noninstitutionalized population of adults aged 45 and over with diagnosed diabetes living in households across the United States. The sample design is described in more detail elsewhere (6). To control for the effect of age on the years since diabetes diagnosis, estimates were age adjusted using the projected 2000 U.S. population from the U.S. Census Bureau as the standard population (7). Estimates for adults aged 45 and over were age adjusted using age groups 45–49, 50–64, and 65 and over. The percentages of vision loss due to each of these eye disorders are among adults aged 45 and over with diagnosed diabetes, not among those with a specific eye disorder. Point estimates and their estimated variances were calculated using SAS-callable SUDAAN version 11.0 (RTI International, Research Triangle Park, N.C.) to account for the complex sample design of NHIS. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. All estimates presented meet NCHS guidelines for the presentation of proportions (8).About the authorsAmy E. Cha, Maria A.
