With the improvement of people’s living standards, the incidence of diabetes in China is increasing year by year. Diabetic vasculopathy is one of the common complications of diabetes, which causes multi-organ damage such as cardiovascular and cerebrovascular damage, and also causes many eye diseases: a. Diabetic retinopathy is the most serious eye complication of diabetes, which often occurs in patients who have diabetes for a long time, and some patients are first eye Some patients know they have diabetes when they first have trouble seeing clearly and then go to the hospital and find changes in the fundus that are typical of diabetic retinopathy. Patients with diabetes often present to the hospital with sensations such as self-conscious flashes of light and loss of vision. Diabetic retinopathy manifests as microaneurysms, hemorrhages, exudates, macular edema, vitreous hemorrhages, and traction retinal detachment in the retina, which can cause severe vision loss or even blindness. Once the diagnosis of diabetes is confirmed it is necessary to go to the hospital for eye examination, fundus fluoroscopy angiography and OCT examination if necessary. Treatment methods include: laser, vitreous cavity injection, vitrectomy, etc. If treated in time, good vision can be maintained. Diabetic cataract is mainly caused by elevated blood sugar and elevated sugar in the atrial fluid, which changes the osmotic pressure of the crystal, causing swelling, fracture and disintegration of the crystal fiber, and eventually the lens turns from transparent to cloudy. The treatment options are cataract extraction (cataract ultrasound emulsification) and IOL implantation surgery. Refractive abnormalities Myopic refractive error can occur when blood sugar is high, and farsighted refractive error may occur when blood sugar is lowered, and it is often accompanied by astigmatism. Therefore, it is important to control blood sugar. Patients with neovascular glaucoma may have eye swelling, eye pain, photophobia, and may be accompanied by ipsilateral headache, nausea and vomiting. The examination reveals elevated intraocular pressure and neovascularization on the iris surface, which mostly occurs in the late stage of diabetic retinopathy that is not effectively controlled, and the treatment effect of this lesion is poor. Treatment: retinal laser treatment of diabetic retinopathy is the fundamental treatment; anti-glaucoma drugs are taken orally, dotted eyes, or anti-glaucoma surgery is performed to lower the intraocular pressure. Eye neuropathy affects the function of the motoneurysm and abducens nerve, which can lead to ptosis, blurred vision, double vision, headache, dizziness, extraocular muscle paralysis, eye strabismus, etc. The prognosis is generally good. When the blood supply of the optic nerve is damaged, neuroinflammatory reactions may occur, which may result in varying degrees of visual acuity loss or even complete blindness. It manifests as optic papilloedema, ischemic optic neuropathy, and optic nerve atrophy. When suffering from diabetes-related eye lesions, treating diabetes and controlling blood sugar is the basic key, and endocrinologists and ophthalmologists need to work closely together to assist patients with treatment. If you need to undergo eye surgery, it is recommended that you do not operate for the time being when your blood sugar is unstable. Patients with diabetes must have their eyes checked regularly for early detection and treatment. Middle-aged and elderly people without a history of diabetes should also have regular medical checkups to keep an eye on their health.
