According to a new study from the University of Pennsylvania in Philadelphia, depression may be associated with more severe dry eyes disease and overall symptoms. Dry eye disease is a common condition that occurs when tears cannot provide enough lubrication for the eyes.
Tears are necessary for maintaining the eye’s health and for providing clear vision. Dry eyes can often be a chronic problem, particularly in older adults. When you blink, tears spread across the eye’s front surface, known as the cornea. Tears provide lubrication, washing away any foreign matter, reducing the risk of eye infection, and keeping the eye’s surface smooth and clear.
People with dry eyes may experience irritated, scratchy, gritty, or burning eyes. It may also give a feeling of something in the eyes, blurred vision, and excess watering. There are many known causes and risk factors of dry eye disease, but this new study sheds light on a new possible association.
The study published online in JAMA Ophthalmology examined the association between depression and the severity of dry eye disease symptoms and signs. These included markers of inflammation in a secondary cross-sectional and longitudinal analysis of data from the dry eye assessment and management study. This study involved patients with moderate to severe symptoms and signs of dry eye disease. There were a total of 535 patients who were followed for one year.
The study found that patients who screened positive for depression had worse dry eye disease symptoms. Participants’ dry eye disease was based on the Ocular Surface Disease Index (OSDI) and Brief Ocular Discomfort Index. A lower Mental Component Summary Score indicated depression.
Study authors concluded the study by saying, “Identifying depression and considering treatment, including systemic medications, may be useful in managing patients with dry eye disease. Patients with more severe dry eye disease concerns or sign measurements may benefit from comorbid psychiatric screening.”
More research is needed to understand the connection between depression and dry eye disease. There is currently no evidence to suggest that depression leads to dry eye disease or vice versa.
Eye and Brain Health
Studies such as this draw attention to the importance of eye health in an aging population. Poor vision can significantly affect every aspect of daily life. So, it’s essential to help support strong and healthy vision as you age. 20/20 Vision contains a unique formula of important vitamins and nutrients to help protect macular health and maintain eyesight.
