Diabetes disease and eye

Diabetes disease can put out of action seeing

The body of diabetics can not use and store sugar properly.High sugar levels can harm nerve layer that provide seeing.This harm in nerve layer is called as diabetic retinopathy.

Diabetic Retinopathy Types

1. Not Proliferative One

In this period,blood and leakage occur from small blood veins in nerve layer of eye.This leakage liquid leads to swelling of nerve layer and occuring deposit called exudative.If there is decrease of seeing,this usually depends on macular edema or maculer ischemia.

Macular edema is severe part of eye to see,and also ,it is the area of small part swelling which is called macular in the centre of nerve layer.Swelling occurs as a result of leakage in blood veins.This situation is major reason of vision loss on diabetics

Macular ischemia occurs when small blood veins choke.Because macular can not be fed with blood that maintains to function properly,vision clouds.

When anormal new veins occur on the eye nerve and nerve layer,this situation is called as proliferative diabetic retinopi.In proliferative retinopi vision loss goes more slowly.Because central and enviromental vision are affected together.



VITREOUS BLEEDING

Vitreous is called as a stuff that fills inside of eye.Vitreous bleeding is not only reason of permanent vision loss.

Traction with retina decolman:When proliferative retinopi occurs,scar tissue shrivels and it draws retina and remove retina from normal position.Wrinkles in macular causes distorted vision.

Neovascular glaucoma:Sometimes,intense embolism in retina leads to anormal vein formation on the iris and eye liquid is pretended to flow to the outside.Pressure in the eye rises and there occurs neovascular glaucam disease called to harm eye nerve.

HOW CAN BE DIAGNOSIS DIABETIC RETINOPI ?

The best way to determine changes in the eye is going to the eye examination.Your oculist can determine your disease before your aware.If your doctor finds diabetic retinopi,he can take colored photos in order to understand if it is necessary for treatment.In this treatment yellow drug is given from the arm and is taken photos of inner eye.With this tratment it is understood in which degree is disease.

Cigarette negative effects on kidney patients

First studies, that indicate negative effects on kidney patients of smoking,have been done on patients who are on type 1 diabetes mellitus.It’s understood that on type 1 diabetic patients who smoke, growing risk of nephropathy is more according to non smokers. Smoking increase growing risk of microalbumunuri significantly, on type 1 diabetic mellitus patients.Moreover,it increases transition to nethropthy period from microalbumunuri period.Biesenbach and his friends appointed that decrease of keratin in clirensin has more reduction on both type 1 and type 2 diabetic mellitus patients from who smoke according to non smokers.


On a research ,which Sawicki and his friends have done,is indicicated that from type 1 diabetic mellitus patients whose blood sugar and blood pressure are got under control, in people quitting smoking,decreasing speed in glomeruler filtration ‘s speed slows down according to those who continue to smoke.This evidence is important in terms of pointing out that: by quitting cigarette patients can benefit from this, even after devoloping of diabetic nethropathy.


Smoking is known to have negative efffects on other kidney diseases except from diabetic netropathy disease.In big epidemiological study, which is big research MRFIT (Multiple Risk Factor Intervention Trial),have been seen that risk of last period kidney disability is more in ones who smoke according to non smoker ones.Smoking incresing effect in growing of kidney disability is indicated on other chronic kidney diseases like chronic glomerulonephritis,polistic kidney disease and lupus nephritis diseases.Besides,smoking can accelerate renal artery stenosis’s and ischemic nephropathy’s development by facilitating atherosclerosis on renal artery and its arms.


Also efforts should be done in order to quit cigarette on patients ,who was started dialysis treatment due to the last period kidney disease.
