Integrated knowledge of diabetes caused by eye disease
Diabetic eye complications are not only common, but often many patients are blind due to failure to take timely and effective treatment. For any diabetic patients, you must conduct regular ophthalmology examinations. Don’t just go to the doctor if you have visual disorder or other eye discomfort.
In fact, the damage caused by diabetes in the eyes is very extensive. Diabetic retinopathy is one of the most severe microvascular complications in people with diabetes, and it is also the main cause of blindness. Cataract is a common ophthalmosis of the transparency of the eyes. Diabetes can promote the occurrence and development of cataracts, especially in the state of long -term hyperglycemia toxicity. The refractive change of the eye is also an abnormal abnormalities in patients with diabetes. Patients often feel blurred vision, mostly short -term or excessive, which is related to the severe fluctuations of blood sugar. When the low decrease is faster, it is manifested as a hyperopia. This lesion can return to normal within a few weeks of diabetes. The incidence of glaucoma is also significantly higher in patients with diabetes. The onset of primary open -angle glaucoma may be related to the hardening of the small beams of the front room, and the outflow of the housing water is not smooth.
Newborn vascular glaucoma mostly occurs in diabetic hyperopia retinopathy. Eye neuropathy: Eye movement nerve damage is diabetic vascular neuropathy, and eye muscle paralysis often occurs suddenly. Among them, moving eye nerve injury is the most common, manifested as the upper eyelid drooping, limited eye movement, and resurgence; followed by exterior nerve, manifested as an external eye paralysis. Eye movement nerve injury is generally good, but the course of disease may last more than 8 weeks.
Neuritis reactions may occur when the nourishing blood vessels in the optic nerve, manifested as visual nipple edema, and the optic nerve atrophy occurs in the late stage. Clinically manifested as a decrease in vision to varying degrees or even blindness. Eye autonomic neuropathy can cause pupils to regulate the light reflection regulatory obstacles, and to adapt to dark adaptation and poor light adaptation; there will also be regulatory obstacles to lacrimal gland secretion, dry eyes or easy to cry.
Diabetic eye disease is a variety of complications caused by diabetes in the eyes. It is like diabetes can cause heart, brain, liver, bile, kidney, gastroats, bladder, skin, oral, bone, muscles, etc. The same damage can cause vision, intraocular pressure, eyelids, conjunctivals, cornea, iris, anterior calamus, ciliary body, crystal, vitreous, etc., especially retinal damage. Therefore, during prevention and treatment, the treatment of diabetes is the fundamental, and the treatment of eye damage is symptomatic. The occurrence time of various chronic complications of diabetes generally starts after 5 years of diabetes. The morning and evening and severity of them are directly related to the control of blood sugar control, blood lipids, and blood pressure. Therefore
* For patients with type 1 diabetes, they should check various chronic complications of diabetes once a year after 5 years of onset.
* For type 2 diabetic patients, because when they find diabetes, diabetes have been often used for many years. Therefore, they should check the occurrence of chronic complications once a year when they discover diabetes.
Diabetic eye disease is one of the most common chronic complications. It can reduce the vision of patients and eventually lead to blindness. The blindness rate is 25 times that of normal people. The most important cause of blindness in the world is diabetic eye disease, and patients must not be ignored. Diabetes can cause various eye diseases, such as corneal ulcers, glaucoma, vitreous bleeding, etc., but the most common and most impact on vision is the two types of diabetic retinopathy and cataract.
Prevention of diabetic retinopathy
* Control blood sugar
* Control blood pressure
* Control blood lipids
* Quit smoking
* Avoid strenuous exercise when there are retinopathy, otherwise it will easily cause fundus bleeding and pay attention to the lesion lesions.
* Regularly undercutial examination: Type 1 Diabetes is checked once a year after 5 years of onset, and type 2 diabetes should be checked once a year after diabetic.
Early detection of diabetic retinopathy
When diabetic patients have the following manifestations, they should find ophthalmologists to check their eyes as soon as possible, because these performances indicate that you may already have diabetic retinopathy:
* Visual vague
* Poor vision at night
* There is a shadow floating in front of the eyes
* Scope of vision of both eyes (vision) shrinks
After arriving at the hospital, the doctor will check the common methods of retinal lesions to check::
* Vision: It is the easiest way, but many early retinal lesions do not affect vision. Therefore, vision examination alone cannot accurately evaluate the retinal lesions.
* Eye mirror examination: The most commonly used method is that after the pupils, doctors directly observe the changes in the bottom of the retina with the bottom mirror, which can initially evaluate the degree of retinal lesions.
* Found fluorescent radiography: The most accurate method is that after intravenous injection of the film, the degree of retinal lesions accurately observed the degree of retinal lesions with a special camera can accurately install the retinal lesions. And decide whether to perform laser optical treatment.
Introduction to the treatment of retinal disease
The role of laser light therapy:
* It can solidify the bleeding point to prevent the retina from bleeding
* Close neonatal blood vessels to prevent further development of retinopathy
* Save vision further deterioration
Diabetes is one of the risk factors that cause cataracts.Regardless of type 1 diabetes or type 2 diabetes, the risk of cataracts has increased significantly.Cataracts caused by diabetes are different from senile cataracts. Diabetic cataracts can occur in adolescent patients and develop rapidly.But sometimes the two are not easy to distinguish, because some patients with diabetes have both diabetic cataracts and senile cataracts.A person has a cataract, as if the lens of a car camera is opaque.The following performance prompts may have cataracts:* Visual cannot be clear
* Clouds in front of the eyes
* Sunshine, the light is not dazzling

* Changing glasses, vision improvement is not obvious
* Decrease vision.
