My dad has had diabetes for a long time. A few days ago, his vision suddenly deteriorated. When the doctor examined him, the doctor told that a blood vessels had ruptured. He has prescribed medicines. How does the vessel ruptures? Can the problem be treated with laser or surgery?

With the help of laser rays, the hole can be sealed-off, which stops the leakage and resoles the swelling. The laser is also applied to prevent the detachment of the retina. However, it is important not to delay the treatment by laser. Since most people start treatment too late, so the benefit is minimal.

How to know about damage by diabetese?

The only method for prevention is regular check-up by some physcian. And whenever there is a doubt go to eye specialist. Best way is annual check-up.

When the defect has been started then different test become compusory. OCT, FFA, etc

My father is feeling that his eyesight is continuously deteriorating. He has diabetes and he doubts that his eyesight is getting worse due to diabetes. How diabatese damages eyes?

Worrisome aspect of diabetes is that the damage caused by it appears very late. And usually when it comes into knowledge, it is too late. The time for best treatment may already have passed!

• If the diabetese is properly controlled and kept under constant control, it has very little effect on the eye. However, if it is not properly controlled, then the eyes can be affected in several ways as follows:
  1. In old age, because the retina and blood supply system becomes weak and diabetes also weakens them, the chances of getting worse at this age are also higher.
  2. Diabetes damages the lens of the eye which is actually transparent but becomes opaque. The common name for this disorder is cataract.
  3. Worst damage occurs in the retina. The walls of retinal blood vessels are damaged and they start to leak and break.
  4. Due to this, the blood components leak into various parts of the retina and cause swelling of different portions of the retina. This leads to decrease in retinal sensitivity to light and decrease in vision. At this stage, generally glasses do give any benefit.
  5. Many blood vessels are blocked and results into stoppage in blood supply for different portions of the retina. If the macular vessels are affected, then vision is severely decreased. If blood supply of other parts is only affected, then vision may not be decreased at this stage. They lead to formation of membranes, which contract. The vessels in these membranes frequently rupture and cause recurrent bleedings in the eye.
  6. Diabetes can damage the cornea.
  7. If the optic nerve is damaged, the eye may become completely blind.
  8. A very devastating complication is neovascular glaucoma. This is a preventable complication but when it gets established then very very difficult to treat!

?What is the effect of diabetes on retina

The visual system cannot function properly due to impaired retina.

1. Many blood vessels are blocked due to diabetic damage, which leads to ischemia of many parts of the retina. This results into lack of oxygen supply which leads into formation of membranes on the retina and into the vitreous. These membranes that form on the retina reduce vision. The blood vessels in these membranes are very fragile, which repeatedly rupture and bleed, which clots on the retina or cloudifies the vitreous and causes reduction of vision.
2. These membranes contract and cause detachment of retina; they may make breaks in the retina leading to detachment of retina. These consequences may lead to permanent loss of vision especially if not managed timely.

Does the operation of retina is successful? People are warning us. We are also afraid that the operation of the retina will not be benficial and the vision will be completely lost. It is heard all over that the retinal disease is incurable?

The problem of retinal impairments is very important in Pakistan. The main reason for this is that there are very few places for its treatment, and there are very few doctors trained to treat it. As a result, people develop a frustrated and careless attitude towards treatment of retinal disorders, so the disease goes on progressing far beyond. When the treatment is approached the disease is really incurable. In fact, the delay in initiating treatment makes the cure uncertain. However, even at that stage it is possible to at least reduce the amount of disability.

With the emergence of innovative methods of treatment, 90% of patients can now be treated successfully, but many of them have to undergo a second or third operation. It is extremely difficult to predict about the prognosis.

Most of such patients do not benefit from laser treatment. Intravitreal injections are mostly dangerous and there is risk of development of tear in the retina due to these injection.

Most of these patients need vitrectomy operation.
