The most common cause of blindness in diabetic patients is diabetic retinopathy. The condition cannot be treated with oral medicines and eye drops. If the patient has diabetic retinopathy, laser surgery is done. Corticosteroid injections are given in the eye. Some anti vascular proliferative medicines are also useful. If the patient has cataract, eye surgery is done.
If there is glaucoma, it is treated with anti-glaucoma medicines. If you want to know about how to cure diabetic blindness, you must consider the following treatment methods and laser surgeries.
Treatment Methods for Diabetic Blindness
Laser Surgery for Diabetic Retinopathy
If the patient has diabetic retinopathy up to the third stage of the eye disease, treatment is not required. However, treatment is needed if the patient has macular edema. For preventing diabetic retinopathy progression, the patient has to control blood sugar. There is also a need to control blood pressure and cholesterol.
For the treatment of proliferative retinopathy, laser surgery is done. The surgery helps in shrinkage of abnormal blood vessels. In this procedure, the area situated far from the macula is burned with laser. More than two sessions of surgery are required for this. There may be side vision loss due to the surgery, but it helps in saving the remaining eyesight.
Diabetic patients should get regular dilated eye exams, as the laser surgery is more effective before the bleeding of the new blood vessels starts. Laser surgery can be done if the bleeding has already begun, depending on the amount of bleeding. If there is severe bleeding, vitrectomy surgery may be required. In this type of surgery, blood from the eye center, which is also known as vitreous gel, is removed. Local anesthesia is used for this surgery.
In vitrectomy, a small incision is made in the eye and the vitreous gel is removed with the help of an instrument. Replacement of the vitreous gel is done with salt solution. Since the vitreous gel mostly contains water, the patient doe not find any difference between the gel and the salt solution. Usually, the patient can return home after the surgery.
Some patients may need to be admitted in the hospital overnight. After the surgery, there is redness and sensitivity in the eyes. For some days, the patient has to wear an eye patch for the protection of the eyes. The patient has to use medicated eye drops that prevent infection.
Laser Surgery for Macular Edema
Focal laser surgery is done if the patient has macular edema. In this surgery, the area where there is leakage around the macula is burned with laser. Due to burns, the fluid leakage becomes slow. This decreases the retina fluid. In this surgery, one session is required and further treatment is prescribed. This surgery may be done more than once. The surgery helps in stabilizing vision. It decreases the vision loss risk considerably. Improvement of vision is possible if there is vision loss.
If macular edema affects both eyes, laser surgery is done in one eye first and the second eye is treated several weeks after the first surgery. Research has shown that macular edema treatment is more effective in treating vision loss with Lucentis drug. When this drug is injected in the eye along with Avastin or Aylea drugs, it decreases the fluid leakage and stops the formation of new blood vessels.
