Bressler NM, Varma R, Doan QV, et al. Underuse of the Health Care System by Persons With Diabetes Mellitus and Diabetic Macular Edema in the United States. JAMA Ophthalmol. 2014;132(2):168–173. doi:10.1001/jamaophthalmol.2013.6426
Thickening of the center of the retina, diabetic macular edema (DME), is the most common cause of visual loss due to diabetes mellitus. Treatment of DME has improved dramatically, and the prompt diagnosis of DME and referral of these patients have become more critical. Nonetheless, awareness of and care for DME in the US population is uncharacterized.
To characterize eye care and awareness of eye disease among persons with DME in the general US population.
Design, Setting, and Participants
Cross-sectional analysis of data from participants in the 2005 to 2008 National Health and Nutrition Examination Survey 40 years or older with diabetes mellitus and fundus photographs.
Main Outcomes and Measures
Among persons with DME, (1) awareness that diabetes has affected their eyes; (2) report on the last time they visited a diabetes specialist; (3) report on their last eye examination with pupil dilation; and (4) prevalence of visual impairment.
In 2010, only 44.7% (95% CI, 27.0%-62.4%) of US adults 40 years or older with DME reported being told by a physician that diabetes had affected their eyes or that they had retinopathy; 46.7% (95% CI, 27.5%-66.0%), that they had visited a diabetes nurse educator, dietician, or nutritionist for their diabetes mellitus more than 1 year ago or never; and 59.7% (95% CI, 43.5%-75.9%), that they had received an eye examination with pupil dilation in the last year. Among persons with DME, 28.7% (95% CI, 12.7%-44.7%) were visually impaired (defined as visual acuity worse than 20/40 in the eye with DME) based on visual acuity at the initial examination and 16.0% (95% CI, 2.5%-29.4%) based on best-corrected visual acuity.
Conclusions and Relevance
Many persons with diabetes mellitus in the United States are not getting care that can prevent visual impairment and blindness. Strategies to increase awareness are warranted, especially given the recent availability of improved therapies for DME.
