Which type of diabetes causes diabetic retinopathy?
The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.
What causes diabetic retinopathy?
Diabetic retinopathy is caused by high blood sugar due to diabetes. Over time, having too much sugar in your blood can damage your retina — the part of your eye that detects light and sends signals to your brain through a nerve in the back of your eye (optic nerve). Diabetes damages blood vessels all over the body.
What are the two types of diabetic retinopathy?
Now, getting to the types of diabetic retinopathy; it is classified into two major types, i.e. ‘Non Proliferative Diabetic Retinopathy (NPDR)’ or ‘Early Diabetic Retinopathy’ and ‘Proliferative Diabetic Retinopathy (PDR)’ or ‘Advanced Diabetic Retinopathy’.
Do all type 1 diabetics go blind?
Nearly 98% of patients with type 1 diabetes and 78% with type 2 diabetes are expected to develop minimal retinal damage after having diabetes for more than 15 years.
Which type of diabetes causes blindness?
Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye (retina). It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight.
Do all type 1 diabetics get retinopathy?
Vision-threatening retinopathy is rare in type 1 diabetic patients in the first 3–5 years of diabetes or before puberty. During the next two decades, nearly all type 1 diabetic patients develop retinopathy.
How does presbyopia occur?
Presbyopia is caused by a hardening of the lens of your eye, which occurs with aging. As your lens becomes less flexible, it can no longer change shape to focus on close-up images. As a result, these images appear out of focus.
What causes blurred vision in type 2 diabetes?
In a person with diabetes, fluid can move into and out of the eye due to high blood sugar levels. This can cause the lens of the eye to swell. As the shape changes, blurriness results, because the lens is the part that focuses light onto the back of the eye.
When does diabetic retinopathy occur?
Although retinopathy usually does not appear for approximately five years after a type 1 diabetes diagnosis, it may already be present when type 2 diabetes is diagnosed. After 15 years of having diabetes, 98 percent of those with type 1 diabetes and 78 percent of those with type 2 have some degree of retinal damage.
Is it possible to reverse diabetic retinopathy?
Can diabetic retinopathy be reversed? No, but it doesn’t have to lead to blindness, either. If you catch it early enough, you can prevent it from taking your vision. That’s why it’s vital to have regular visits with an Ophthalmologist or Optometrist who’s familiar with diabetes and retina treatment.
Does metformin affect vision?
Now researchers have also observed that metformin (which is sold under brand names such as Glucophage, Glumetza, and Fortamet) may also decrease the likelihood of age-related macular degeneraton (AMD) — a leading cause of vision loss among people age 50 and older.
Can lowering blood sugar improve vision?
While high blood sugar can change the shape of the lens in your eye, low blood sugar doesn’t and this particular vision issue can be corrected sooner by getting your blood sugar back to normal from a meal or snack.
Can someone with type 1 diabetes live a long life?
While the lifespan of people with type 1 diabetes has increased progressively since the advent of insulin therapy, these patients still experience premature mortality, primarily from cardiovascular disease (CVD). However, a subgroup of those with type 1 diabetes survives well into old age without significant morbidity.
How long can you live with type 1 diabetes?
The investigators found that men with type 1 diabetes had an average life expectancy of about 66 years, compared with 77 years among men without it. Women with type 1 diabetes had an average life expectancy of about 68 years, compared with 81 years for those without the disease, the study found.
Can diabetes Type 1 be fatal?
People with type 1 diabetes must take insulin daily. If left untreated, the excess sugar in the blood can cause severe damage to the body and may even be fatal. Complications that may result from type 1 diabetes include: Heart disease.
