“Diabetes can trigger the eye disease.” Why should we raise this question? Because diabetes is a systemic metabolic diseases, metabolic disorders can cause全身各器官a series of metabolic abnormalities, resulting in microvascular and large vessel nervous system lesions . Eyes, can be seen from the outside in, front-to-multiple sites affected by the disease.
The most common eye disease caused by diabetes is diabetic retinopathy, in addition the more common are cataracts, eye nervous system disease, glaucoma and cornea, conjunctiva, eyelids and other parts of the lesion. Common are the following circumstances:
1. Diabetic retinopathy
This is the earliest symptom of diabetes is diabetes most common and most serious complication is one of the important reasons leading to blindness, in the four major eye disease leading to blindness, to occupy first. It is estimated that people with diabetes in our country, approximately 35% of people have retinopathy, and its incidence rate increased with the growth duration and age increased. In general, the course of more than 10 years, 50% of the patients had retinopathy; disease duration of more than 20 years, 80% of the patients had retinal lesions.
2. A sudden drop in visual acuity
Optic neuropathy caused by diabetes, is a part of cranial nerve lesions, often ischemic in nature. Manifestations of a sudden drop in visual acuity, visual field defects, fundus examination showed optic nerve edema or atrophy, if accompanied by other cranial neuropathy may occur in other relevant symptoms.
3. As the objects in pairs, or strabismus
In addition to optic neuropathy caused by diabetes, it can also cause oculomotor nerve, trochlear nerve, abducens nerve lesions. Decrease vision often occurs, depending on the material in pairs, headache, nausea, symptoms such as eyelid lift can not afford. Cranial neuropathy can be a single place, can simultaneously; can be monocular, binocular can happen. Diabetes caused by the occurrence of cranial nerve lesions, generally considered to be due to nutrition of their nerves caused by small blood vessels occur microthrombus. At the same time diabetic patients than normal increase in plasma fibrinogen, plasma enhanced coagulation, increased blood viscosity, platelet adhesion to the vascular wall opportunities and the chance of an increase in platelet aggregation with each other. Because infarct size is small, even if the CT scan or MRI is also difficult to detect infarct.
4. Glaucoma morbidity was significantly higher than normal population
In patients with diabetes in the same intraocular pressure of glaucoma cases, glaucoma than those without diabetes in patients with glaucoma, the optic nerve more susceptible to retinal damage. Up to a certain degree of diabetic retinopathy, retinal ischemia and the state can produce neovascular glaucoma. Such difficult to control intraocular pressure of glaucoma, blindness, high rate.
5. Eyelids can also be changed
Diabetic patients with low resistance, high incidence of pyogenic infections, often recurring boils swollen eyelid, sty, blepharitis, etc., often long treatment. Because fat metabolic disorders, diabetes, a higher incidence in patients with eyelid yellow tumor, usually located inside the upper eyelid, bilateral symmetry, yellow skin, spots, light uplift.
6. Bulbar conjunctiva changes
Bulbar conjunctiva in patients with diabetes are often visible small blood vessels to expand, diameter uneven, some showed cord-like or irregular. May also have small blood vessels rupture and bleeding, manifested as conjunctival reddening. This phenomenon can occur in diabetic patients, but also can occur in elderly people in general do not need special treatment, a few days to absorb on their own.
