What is Diabetic Retinopathy?
Diabetic retinopathy is a medical condition in which damage occurs to the retina due to complications from diabetes. The retina is responsible for transferring the image from the eye to the brain, and damage to the retina can negatively impact vision. There are two main types of diabetic retinopathy - non-proliferative and proliferative.

Non-proliferative retinopathy involves small swelling and weak areas in the retina's blood vessels, which can leak fluid or bleed into the retina. This causes damage to the photoreceptors and vision loss over time if not treated. Proliferative retinopathy occurs when new blood vessels grow on the surface of the retina or into the vitreous gel. These new blood vessels are abnormal and fragile, and can rupture, causing vision loss or total blindness.

Risk Factors and Prevalence

The main risk factor for developing diabetic retinopathy is having diabetes - especially type 1 diabetes or uncontrolled type 2 diabetes. The longer a person has had diabetes, the higher the risk. Other risk factors include having had diabetes in pregnancy, high blood pressure, high blood lipid and cholesterol levels, obesity, smoking, and kidney disease.

Diabetic retinopathy is actually on the rise globally due to the growing diabetes epidemic. In the US, diabetic retinopathy affects over 7 million people and is the leading cause of blindness among working-age adults. It is estimated that over 1 in 3 Americans with diabetes have some stage of diabetic retinopathy. This high prevalence carries significant economic and productivity costs.

Impact on Workforce Productivity

Vision loss or blindness due to Diabetic Retinopathy significantly impacts individuals' ability to work and contributes to lost productivity. Even at early or mild stages, individuals may experience blurred or decreased vision that makes tasks like reading, using computers, or driving difficult. As the disease progresses, more severe vision impairments can make many job functions impossible without accommodations.

The impact on the workforce is two-fold. First, individuals dealing with vision problems from diabetic retinopathy face decreased work performance, job changes, reduced hours or responsibilities, and missed time from work for doctor visits and treatments. This leads to lost productivity for employers. Second, as more people either become disabled or blind from advanced diabetic retinopathy, it means a decreased workforce and tax revenues from lost wages.

Studies have estimated the total annual cost of diabetic retinopathy in the US due to lost productivity and wage earnings to be over $500 million. Those with proliferative or severe vision-threatening retinopathy face especially high risks of job loss and unemployment due to more advanced impairments. This has ripple effects through the economy and stresses public support systems.

Early Screening and Treatment Critical

The good news is that proper management and treatment of diabetes along with early screening for retinopathy can help prevent or delay much of the associated vision loss and workforce impacts. The American Diabetes Association recommends that all individuals with diabetes receive a comprehensive dilated eye exam at least once per year.

During an eye exam, an optometrist or ophthalmologist uses special instruments and eye drops to dilate the pupil so they can thoroughly examine the retina for any signs of non-proliferative or proliferative retinopathy. If caught early, before significant vision loss occurs, lasers, injections or surgery may successfully treat or repair damaged areas to stabilize or improve vision.

Promoting diabetes control through lifestyle modifications like diet, exercise, medication adherence and regular check-ups is key to reducing the risk of vision-threatening retinopathy developing at all. Employers can support employees through insurance coverage of annual diabetic eye exams and by offering wellness programs that focus on diabetes prevention and management. Identifying and treating any cases of undiagnosed or uncontrolled diabetes is also important for workforce health.

Rising Healthcare and Societal Costs

In summary, diabetic retinopathy poses a growing threat not only to the health of individuals but also to workforce productivity, business costs, and broader economic impacts as its prevalence climbs in step with increasing rates of diabetes. Vision loss from this disease costs the US hundreds of millions annually already and risks rising further without improved prevention, screening, and treatment access. Employers have a stake in supporting employees’ eye and overall health to protect the bottom line while minimizing lost time, talent and earnings due to a largely avoidable cause of vision impairment and disability. Broader policy efforts to control diabetes and expand access to quality healthcare can help stem its damaging societal and economic consequences.
