Diabetic retinopathy alert to blindness crisis
Retinopathy is common in middle-aged and elderly people, and diabetic patients should receive mydriasis examination at least once a year. (Photo/Zhang) Tainan Municipal Hospital recently admitted a 60-year-old female patient named Lin. At the clinic, she reported that she had high blood pressure and diabetes. Although she takes drugs, her blood sugar is not well controlled. One morning, I got up to go to the toilet, and suddenly a mass of black ink gushed out in front of my eyes, and then slowly turned into a black shadow blocking my view. Finally, my vision was almost completely lost, and even the first few fingers could not recognize it. Later, the doctor diagnosed diabetic retinopathy with vitreous hemorrhage, and after several months of treatment, he slowly recovered his vision.
Wang, an ophthalmologist at Tainan Municipal Hospital, said that diabetes is one of the diseases of modern civilization, which will be complicated by pathological changes of multiple organs of the body. The most common complication of eyes is retinopathy. There are usually some punctate bleeding in the early stage, which is called "basic diabetic retinopathy". At this time, it will not affect vision, and there will be no uncomfortable symptoms. Usually found during regular inspections. There is no need to give any treatment at this stage, as long as you follow up regularly.
If proliferative diabetic retinopathy is not treated, it will lead to severe vision loss and near blindness after 5 years.

Finally, due to long-term hypoxia, new blood vessels may be produced.
Dr. Wang said that once new blood vessels appear in the retina, it is called "proliferative diabetic retinopathy" and it needs active treatment at this time. If left untreated, new blood vessels may grow longer and more, which will eventually lead to blood vessel rupture, vitreous hemorrhage or retinal detachment caused by traction, resulting in severe vision loss.
Dr. Wang said that once early proliferative diabetic retinopathy is found, retinal laser treatment should be accepted as soon as possible, and most patients can maintain good vision and quality of life.

In addition to blurred vision, there will be symptoms such as high intraocular pressure, red eye and swelling pain, which will lead to permanent blindness in severe cases, which is the main reason for blindness at the age of 265,438+0-64.
In addition, there are many eye diseases related to diabetes, including diabetic retinopathy, cataract, neovascular glaucoma and diabetic retinopathy, among which diabetic retinopathy is the most common. Therefore, Dr. Wang suggested that diabetic patients should have a mydriasis examination at least once a year regardless of whether they have eye symptoms. As long as it can be found and treated early, most patients can maintain good vision and quality of life.
