A new medical study has revealed that people who suffer from depression are more likely to have self-reported vision loss. According to the study, which was published in the JAMA Ophthalmology journal, researchers analyzed data from more than 10,000 adults aged 20 and older who took part in the US National Health and Nutrition Examination Survey between 2005 and 2008. The rate of depression was about 11 percent among people with self-reported vision loss and about 5 percent among those who did not report vision loss. After accounting for a number of factors, including age, sex and general health, researchers concluded there was a significant association between self-reported vision loss and depression. The study did not, however, show that one causes the other.
