Retinal Lasers

What is a laser?

 

A laser is an instrument that produces a pure, high-intensity beam of light energy. The laser light can be focused onto the retina, selectively treating the desired area while leaving the surrounding tissues untouched. The absorbed energy creates a microscopic spot to destroy lesions or weld tissues together.

 

Who needs laser surgery?

 

Lasers were first used to treat eye diseases in the early 1970's and have become the standard of care for previously untreatable disorders. For many patients, laser can preserve or prevent vision loss if given in a timely fashion.

 

Your eye will almost always look and feel normal with retinal diseases, even when there is hemorrhaging and leakage in the back of your eye. Your sight may also be normal for a while despite the presence of potentially blinding eye problems.

 

The only way to tell if you need laser surgery is to have a careful, dilated retinal examination, often followed by special testing including OCT scanning and fluorescein angiography (a photographic test that evaluates the eye's circulation). Lasers are commonly used to treat the following eye conditions:

Diabetic retinopathy.

 Diabetes causes circulation problems throughout the body, including the eyes, nerves, and kidneys. The retinal blood vessels are usually like pipes, bringing blood into and out of the back of the eye. In diabetes, however, the vessels may leak, causing the retina to swell and not work properly (diabetic macular edema). Vision is affected when the swelling involves the central vision area. Laser surgery can seal the leaks, thereby preventing further vision loss.

 

Some patients will have new retinal blood vessels grow to replace some which have closed from the diabetes (proliferative diabetic retinopathy). While this sounds good, these new blood vessels can cause blindness from bleeding and scarring. Laser treatment can often prevent severe vision loss by making these new vessels disappear.

 

 

Retinal vein occlusions.

The small blood vessels that drain blood from the retina (retinal veins) can sometimes become blocked as part of the aging process. This is more common in patients with diabetes or high blood pressure. A retinal vein occlusion can cause the retina to swell with fluid and blood, blurring central and peripheral vision. Other times, new blood vessels may grow and cause pain with very high pressure inside the eye (neovascular glaucoma). Laser treatment can help reduce this swelling or cause the new blood vessels to disappear.

 

Age-related macular degeneration.

Some people will develop aging changes in the macula, the portion of the retina responsible for our central reading vision. Most will experience the less harmful dry type, which usually causes minimal visual changes. The more severe, or wet type, causes the macula to swell with fluid and blood. Symptoms of wet macular degeneration include painless blurred or distorted vision. Urgent treatment can often prevent or delay vision loss in some patients with this wet type.

Retinal breaks and detachment.

The retina lines the back of the eye like wallpaper. Retinal tears or rips can occur as part of an aging phenomenon, or following cataract surgery or eye injury. Patients will often see cobweb-like floaters or light flashes when a retinal tear develops. Liquid that normally fills the central portion of the eye (the vitreous) can leak beneath the tear, lifting the retina away from the eye wall. This is called a retinal detachment, which can cause blindness if left untreated. Laser surgery around retinal tears is often able to weld the retina to the underlying eye wall. This can prevent or limit retinal detachment.

 

 
 
Central serous chorioretinopathy (CSC).

 

 

 

CSC consists of one or more “blisters” of fluid (serous detachment) beneath the macula. It can cause central blurriness, distortion, abnormal color vision, blind spots, and temporary farsightedness. Although the vast majority of cases will resolve spontaneously, laser photocoagulation is sometimes necessary for persistent lesions.

 

 

 
 
 
 
 
 
 
 
 
What happens during my surgery?

 

There are no special preparations before eye laser treatment. You should eat normally and take your regularly prescribed medications before surgery.

 

Retinal laser surgery is performed in our office. Eye drops will be given to dilate the pupil and numb the eye. The treatment is performed while you are seated in a chair, similar to the one used for regular eye examinations. You will remain awake and comfortable. Treatment is usually painless, although some patients may require a numbing injection for discomfort or sensitivity to the laser light.

 

The laser treatment usually takes less than 30 minutes to complete, and you can go home immediately following surgery. Arrangements for transportation should be made in advance since you may not be able to drive right away.

 

What are the restrictions and side effects after laser?

 

There are virtually no restrictions following retinal laser surgery, and you should be able to resume your normal activities and work schedule the following day.

 

Most patients notice no vision changes following their laser surgery, although there may be some temporary blurring for several weeks to months. In addition, depending on the condition being treated, some may notice a permanent blind spot or decrease in peripheral and night vision.

 

Will I need more than one laser treatment?

 

It will take several weeks to months before we can tell whether the laser surgery has been successful. Many patients, however, will need more than one treatment to control their eye problem and prevent further loss of vision.
