Diabetes is dangerous for its long and serious complications.For example, visual impairment due to diabetes is very mnogoorazny suffer all structures of the eye.It is no coincidence more than half of the Visually Impaired (and according to some sources - 80%) - diabetics.
Such short-term visual impairment in diabetes as farsightedness and nearsightedness, occur from time to time due to variations in the level of sugar.
Depending on the amount of change of intraocular fluid, which affects the shape of the eye lens - it can become a concave and convex.Accordingly, vision deteriorates vision and distance and near.
Such violations are generally of short duration and can alternate even within one day.When sugar levels returned to normal, they disappear.
After 20 years of living with diabe
cells of the macula are powered from the choroid, which lies deeper.In typical diabetic angiopathy macula breaks down food, which is fraught with the loss of the ability to read or distinguish small objects, though in the future it does not lead to blindness.
effective method to combat macular edema of the retina is to compensate metabolic disorders (carbohydrate, fat and protein), and blood pressure control.In addition, the disease is amenable to medical and surgical treatment.
Resistant clouding of the lens, or cataract, diabetic patients develops in two times more frequently than in healthy people.
Depending on the type of diabetes the haze may be different, even translucent, practically does not reduce its vision or reduces slightly.Such a condition may remain stable for many years.
With the rapid progression of the process may turbidity removal of the lens and replacing it with an artificial one.
This complication is affected retina of the eyeball.The reason - the defeat of the vessels of the retina, which leads to the breakdown of the blood supply to the eye.The result of this persistent violation becomes a significant deterioration and even loss of vision.There are several stages of the disease.
At the first stage of the disease there are isolated cases of occlusion of small vessels of the retina (nonproliferative diabetic retinopathy).At this stage there is not any visual impairment, and this can last for years.
In the second stage ends with blockage of small blood vessels bleeding, and their number can be called significant (preproliferative diabetic retinopathy).
The third stage is called proliferative diabetic retinopathy.Plugged capillaries are more and more, as well as zones of circulatory disorders of the retina.Feeling "hunger", the body triggers the growth of new vessels - the process of neovascularization.
newly formed blood vessels are growing rapidly, and they are extremely fragile and brittle, which can lead to intraocular hemorrhages of different severity.
If bleeding in the retina and vitreous body are small, they can dissolve.Massive hemorrhage in the eye cavity (hemophthalmus) lead to irreversible scarring in the vitreous body and can continue to cause retinal detachment.
Depending on the extent of this process, the central vision is affected.If the newly formed vessels continue to grow in front of my eyes, I blocked the outflow of intraocular fluid way, and then there is glaucoma.
Even if you do not notice until changes or vision loss due to diabetes, visit an ophthalmologist regularly - twice a year.
In a sudden and sharp deterioration of vision due to diabetes - to the doctor immediately!
Follow all recommendations and destination of your ophthalmologist.
monitor the level of blood sugar, because it affects your vision.
