This is what the inside of your eyes look like. Cornea – Is like a window – it let’s light in. Iris – Coloured part of your eye Pupil – Black hole in the iris Sclera – White part of the eye Lens – Focuses like a camera pupil Retina – Is like a movie screen which shows you the picture Optic nerve – Is like a cord that carries the pictures from your DVD player to your TV Aqueous humour – fluid around the lens Vitreous humour – Jelly-like fluid in the eyeball to keep it in shape.
This is a healthy eye Your eyes are like a camera, the light goes through the lens and focuses the picture on the back of the eye. This upside down picture is sent to your brain which turns it the right way up.

Diabetes in the eye If you have bad sugars, this means you could have bad eyes. The veins that carry the blood in your eyes are like rivers. Your diabetes has made lots of tiny rivers in your eyes, so these rivers are very weak. When they break, blood spills into the back of your eyes. It doesn’t hurt so you won’t know that your eyes are bleeding. After sometime your eye goes blurry and it keeps getting worse until you can’t see anymore, everything will go black. The doctor can’t help you see again once it is gone.
Diabetic Retinopathy Not looking after your diabetes can make your eye sick. The blood vessels in your eyes can burst and you will have bleeding in your eye, this will make your eyesight bad.
This is what you might see when looking at things Floaters or Spots Blurred Vision Dark or Empty Spots
Stages of Diabetic Retinopathy Stage 1 Stage 2 Mild Nonproliferative Retinopathy Moderate Nonproliferative Retinopathy The veins are like rivers with weak banks that collapse and start to leak. In stage 1 you wont notice any difference with your sight. The veins are swelling and collapsing more. In stage 2 you still might know it is happening, you will still be able to see.
Stages of Diabetic Retinopathy Stage 3 Severe Nonproliferative Retinopathy Stage 4 Proliferative Diabetic Retinopathy Your veins are blocked and leaking blood. Stage 3 you will have problems seeing. Lots of bleeding in your eyes. Stage 4 you will have bad sight.
Treatment Good news the doctor can use special equipment to stop you from going blind like laser treatment and injections. Laser takes about 10 minutes, you will see a red light, you have to sit very still and look straight into that red light. Laser works by zapping the river banks in your eyes so the river doesn’t overflow, doesn’t make you see any better but stops it from getting worse. The eye specialist can help your eyes with regular treatment, he can’t make you see any better but he can stop it from getting worse. So the sooner you have treatment the better you will be able to keep the sight you have. You will get drops in your eyes to numb them so you shouldn’t feel anything. Next you will be given an injection or laser treatment to stop the bleeding in your eyes. Sometimes you might need both injection and laser. Just remember this is going to help you to keep seeing.
