1. Definition of diabetic retinopathy
What is diabetic retinopathy?


When diabetes is prolonged, blood vessels break down and there is a small bleeding at the end, a condition called non-proliferative diabetic retinopathy. If this becomes severe, it can develop into proliferative diabetic retinopathy, which causes bleeding towards the vitreous.

 

In order to deal with blood before it occurs, it is necessary to find out the cause of the bleeding in advance and treat it, which is called angioscopy, which is a test that looks at the movement of blood vessels. If you look at people with severe diabetes, just before they bleed, when they do a lithography test, they see a tissue called a cloud of neovascularizationNew blood vessels are very easy to burst and bleed. In this case, treatment is carried out immediately.

 

However, in addition to the bleeding mentioned above, there are other forms of diabetic retinopathy. The central part of the retina of the eye is called the macula, and when this macula is taken with a machine called OCT, the normal macula looks like the top right. However, if you have diabetes for a long time, your blood vessels can swell like this. As a result, it has a swollen appearance as shown in the bottom right of the OCT photo, and when this happens, the eyesight decreases a lot. This is called diabetic macular edema. This is also a type of diabetic retinopathy and is a candidate for treatment.

 

2. Treatment of diabetic retinopathy
Diabetic retinopathy, how is it treated?

There are several treatments for three types of diabetic retinopathy: non-proliferative diabetic retinopathy, proliferative diabetic retinopathy, and diabetic macular edema.

 

When our eyes become abnormal and the oxygen that should be delivered to each tissue is not delivered properly, it sends strange signals. He's hungry, so he sends a signal to make blood vessels. Then the blood vessels start to multiply, but this is not the blood vessels that proliferate under normal conditions, so they are supposed to proliferate along the wall, but they proliferate toward the middle of the eye, toward the void. Therefore, because these neovascularities are suspended in the middle of the vitreous, they are very fragile and prone to bursting. These are called retinal neovascularizations, and they are observed in the form of clouds on the angiogram. So, if this is observed, laser or injection treatment is performed to minimize the possibility of future bleeding.

 

What kind of laser is it, to be precise, it is called laser photocoagulation. When the eye is irradiated with a laser to the retinal tissue of the optic cells that are impervious to blood, the neovascularization gradually degenerates over a period of several months.

 

However, if the timing of the laser procedure is missed and the bleeding is severe, surgery will be performedSurgery is performed to insert instruments directly into the eye and perform excision. Silicone oil is also placed in the eye to prevent the possibility of rebleeding after surgery.

 

Next, we're going to look at the case of macular edema. If you have diabetic macular edema, you may be treated with injectionsThere are about six types of injectable drugs for macular edema so far. The injections approved by the authorities are Lucentis, Eylia Biovue, Macaid, and Ozerdex, and there is also an unapproved drug called Avastin, which is very widely used. Each of these drugs has its own advantages and disadvantages, and each patient has a different level of listening, so it is best to leave the choice of drug to the judgment of a specialist.

 

However, if this macular edema is not treated, it can cause permanent damage to the optic cells, and in this case, injection treatment does not improve vision. If this is the case, unfortunately there is nothing more we can do for you. Therefore, it is important to receive injection treatment in advance and check the condition through regular check-ups to prevent this from happening.

 

3. Diabetes and floaters
Is it related to floaters?

Retinal neovascularization usually occurs in diabetics, but neovascularization can actually occur in other parts of the eye. There's also something called choroidal neovascularization. Or there is a disease called retinal vein occlusion, which has findings similar to that of a diabetic patient, and neovascularization can also occur.

5. Eye Supplements and Diabetic Retinopathy
Can eye supplements help?

Among the things that are generally recognized as preventing the progression of diabetic retinopathy, the ingredients called dobesylate and calcium dobesylate are recognized. These medicines are helpful, and commercially available antioxidant supplements are primarily helpful for patients with age-related macular degeneration, but they have not been definitively proven to help patients with diabetic macular edema or diabetic retinopathy.

 

However, as the two diseases progress to the later stages, the damage to the retina itself is similar, so I don't think it's harmful to take it. So if you want to eat it, it's okay to eat it.
