Does diabetic retinopathy cause permanent vision loss?
1. Statistics on people with diabetic retinopathy
There are two main types of diabetes:
1.1 Insulin dependent diabetes
The prevalence of proliferative diabetic retinopathy in people with type 1 diabetes is negligible up to a 5-year period and increases to about 60% after 20 years. Among people with type 1 diabetes, the rate of macular edema increased from less than 5% shortly after diagnosis to more than 20% over a 25-year period.
1.2 Non-insulin dependent diabetes
The prevalence of proliferative diabetic retinopathy increased from 2% at the time of diagnosis to approximately 20% over a 20-year period. The incidence of macular edema is not significant shortly after diagnosis but increases to more than 10% after 25 years. About half of people with type 2 diabetes are treated with a blood sugar-lowering diet or medication. The incidence of retinopathy in people with type 2 diabetes who do not require insulin treatment increases from 10-20% at diagnosis to more than 60% after 20 years.
The prevalence of proliferative diabetic retinopathy increased from 2% at diagnosis to approximately 5% after 20 years. This is the lowest incidence and progression of retinopathy. The incidence of macular edema increased from less than 3% shortly after diagnosis to more than 10% after 25 years.
A recent study conducted at the US Centers for Disease Control and Prevention (CDC) shows that the prevalence of diabetic retinopathy is at a high level, affecting nearly one-third of adults worldwide. 40 years old with diabetes and more than a third of African-Americans and Mexicans. Specifically:
4.2 million adults have diabetic retinopathy, of which 655,000 are vision-threatening. Compared with Caucasians, the more severe (vision-threatening) form of diabetic retinopathy is 3 times more common in Mexican Americans and nearly 3 times more common in African Americans. Male sex, high A1c levels, long duration of diabetes, insulin use and high systolic blood pressure are factors that are independently associated with the occurrence of diabetic retinopathy. The study was conducted as part of the National Health and Nutrition Examination Survey from 2005 to 2008. The full report was published in the Journal of the American Medical Association.
2. How important is prevention in diabetic retinopathy?
However, vision problems and blindness from diabetic retinopathy can all be prevented through:
Good control of blood sugar and blood pressure Detect and treat eye diseases early To To reduce blindness associated with diabetic retinopathy, health professionals must identify and treat those at high risk before vision loss occurs. Prophylaxis in the form of laser treatment for proliferative diabetic retinopathy and macular edema. Improved access to screening and treatment for diabetic retinopathy may also reduce the risk of diabetes-related vision loss.
3. The role of diabetic retinopathy screening
An annual eye exam can identify diabetic retinopathy early, so it can be treated promptly to prevent vision loss and the risk of blindness. However, about half of people with diabetes don't get regular eye exams. The sensitivity of ophthalmoscopy in screening for diabetic retinopathy increases when the physician is trained and experienced in performing eye exams, and ranges from 50 to 100%. Economic evaluations show that screening for diabetic retinopathy costs less than one year of treatment for one's blindness.
In summary, screening for diabetic retinopathy is both effective to prevent blindness and cost-effective. This prevention effort requires improved screening, timely detection, and initiation of health care. To start treatment, all people with diabetes (except those with type 1 diabetes for less than 5 years) must have an annual eye exam by a trained specialist and must be referred for treatment. suitable.
