Why is laser treatment for diabetic retinopathy

Diabetic retinopathy why vision decreases after laser**.

Retina My father-in-law had a 9-year history of diabetes and was diagnosed with stage 3 diabetes by fluorescence contrast and was recommended by the doctor with a laser**. My father-in-law heard from a patient that the laser was not good and would become more and more blind, so he was very burdened and worried that the failure of the operation would be harmful to his eyes. I would like to ask:

Is it necessary to have a laser for this level of condition**? Is laser technology mature for this retinopathy? What is the success rate?

Any surgery is risky, how do you choose between the risks of surgery and the deterioration of your condition? Beijing Li A: The application of laser diabetic retinopathy is a very mature technology.

Your father-in-law's fundus retinopathy has reached stage 3, which is the best time to apply lasers, so don't miss this opportunity. If you wait until the disease has progressed further to stage 4**, the effect may be much worse. After years of clinical application, the success rate of stage 3 retinopathy after laser ** is very high, but the premise is that the blood sugar must be well controlled.

If your father-in-law goes to the ophthalmology department of a regular hospital for fundus laser**, it will generally not fail, and the impact on vision will not be great, let alone the loss of vision. There is not much risk associated with this method, and it will prolong the useful vision time in both eyes. Without laser**, vision will deteriorate further and eventually lead to complete blindness in both eyes.

Therefore, it is recommended that you dispel your concerns and go to the hospital for the laser** as soon as possible (the specific laser** and pre-laser preparation for the surgery should be determined by the hospital's specialists).

What can lasers do? For diabetic macular edema (the macula is the most critical part of a person's vision), laser** can reduce the accumulation of macular exuate to reduce macular edema and prevent further vision loss. Although empirically some patients may have improved their vision after laser, it is generally difficult for vision to return to a normal state.

For severe, nonproliferative diabetic retinopathy (fluorescein contrast shows signs of ischemia in the retina but no neovascularization), laser therapy is designed to prevent neovascularization. In proliferative diabetic retinopathy that has been transited and has been neavascularized, laser photocoagulation of all areas of the retina except the macula (i.e., panretinal photocoagulation) is aimed at regressing the abnormal neovascularization and preventing its further progression. Laser photocoagulation is beneficial in reducing the chance of vitreous hemorrhage and preventing the occurrence of traction retinal detachment or folding.

The role of lasers in controlling the progression of the disease is obvious, but there are certain problems, such as temporary blurred vision, mild vision loss, and visual field defects. Side-by-side.

In most cases, repeated laser** is necessary. Although laser** can play the above role, it cannot** diabetic retinopathy, so even if panretinal photocoagulation has been completed, it must be insisted on until the ophthalmologic follow-up.

Analysis: Hello! With type 2 diabetes, there has been a gradual decline in vision in the past year, and yesterday's hospital examination showed slight bleeding in the fundus, which is mainly a complication of diabetes, that is, the neovascularization of the eye travel deficit, which can lead to vitreous hemorrhage, resulting in vision loss, and even blindness.

Guidance: The best way to do this is to use laser light to calm the ears to prevent vitreous hemorrhage from leading to serious consequences, and at the same time, diabetes should have a regular diet, take drugs on time, regularly review blood sugar and other aspects of the examination such as kidney function tests.

Analysis: Hello, your diabetes should have been for a long time, right? Your situation is likely to be a complication of diabetes, which is retinopathy caused by diabetes.

Whereas, eye lesions caused by diabetes are organic. It is the damage of small blood vessels in the eye caused by diabetes. And your current condition is likely to be cataracts, which means a sharp loss of vision.

Advice: It is very important to recommend that you go to the ophthalmologist for a comprehensive examination of the cleft finger, and at the same time control your blood sugar. To keep fasting and postprandial blood glucose close to normal, glycosylated hemoglobin should be controlled below 7%.

If the diagnosis is indicated, laser** or surgery may be an option. Song Yuan Debate.
