LALES researchers found that over the four-year interval, Latinos developed visual impairment and blindness at the highest rate of any ethnic group in the country, when compared with estimates from other U.S. population-based studies. Overall, nearly 3 percent of Latinos developed visual impairment and 0.3 percent developed blindness in both eyes, with older adults impacted more frequently. Of Latinos age 80 and older, 19.4 percent became visually impaired, and 3.8 percent became blind in both eyes.
U.S. Latinos were also more likely to develop diabetic retinopathy than non-Hispanic whites. Over the four-year period, 34 percent of Latinos who had diabetes developed diabetic retinopathy, with Latinos aged 40 to 59 having the highest rate. Though increasing age did not play a role, Latinos with a longer duration of diabetes were more likely to develop the disease. In fact, 42 percent of Latinos with diabetes for more than 15 years developed diabetic retinopathy. Also, among participants who had diabetic retinopathy at the beginning of the study, 39 percent showed worsening of the disease four years later.
Researchers found that Latinos who already had visual impairment, blindness, or diabetic retinopathy in one eye when they began the study had very high rates of developing the condition in the other eye during the study. More than half of participants who already had diabetic retinopathy in one eye developed it in the other eye.
"These results underscore the importance of Latinos, especially those with diabetes, getting regular, dilated eye exams to monitor their eye health," Varma said. "Eye care professionals should closely monitor Latinos who have eye disease in one eye because their quality of life can be dramatically impacted if they develop the condition in bo
