Laser photocoagulation is a type of laser surgery for the eyes. It's done to treat age-related macular degeneration (AMD). AMD can lead to vision loss.

The retina is the layer of nerve cells in the back of your eye. It changes light into electrical signals. Your retina then sends these signals to your brain. The macula is the extra sensitive, central part of your retina. This area is responsible for the detailed vision in the center of your visual field. AMD harms your macula. Blood vessels may grow under your macula. This causes blood and fluid to leak under it. This excess blood and fluid can lead to vision loss.

Before the surgery, you are given an anesthetic eye drop. An eye doctor then uses a special lens to focus an intense beam of light on the abnormal blood vessels under the macula. This creates burns in small areas of the macula. This seals off the leaky blood vessels. This can help prevent more vision loss.

Laser photocoagulation is just one type of treatment for AMD. AMD is a common cause of severe vision loss in older adults. In rare cases, it can result in total blindness. AMD affects the macula. So you may still have your side (peripheral) vision. But you may have a slow or sudden loss of central vision.

There are two types of AMD: dry and wet. Abnormal blood vessel growth only occurs in the wet type. Laser photocoagulation treatment is advised only for the wet type. Laser photocoagulation is only recommended for some people with wet AMD. Your eye doctor might recommend it if your abnormal blood vessels are grouped tightly together. The procedure is less helpful if you have scattered abnormal vessels. It is also less helpful if they are in the very center of the macula. Your eye doctor may be more likely to recommend the procedure if your vision loss comes on suddenly instead of slowly.

Laser photocoagulation usually doesn't bring back vision that you have already lost. But it may slow down the progression of damage to your central vision.

Other treatment choices for AMD include medicines injected into the eye that reduce abnormal blood vessel growth. Your eye doctor is much more likely to recommend using injected medicines than laser photocoagulation. Talk with your doctor about the risks and benefits of all your treatment choices.

During laser photocoagulation, the eye doctor burns part of the macula. This sometimes causes some added vision loss. You might have a blind spot where the laser makes a scar. In some cases, this vision loss might be worse than the possible vision loss from not treating the eye. This is something to think about when deciding to have the procedure.

Laser photocoagulation has some other possible risks as well. These include:

• Accidental treatment of the central macula, which causes a worse blind spot
• Bleeding into the eye
• Damage to the retina from the laser scar, right away or years later

There is also a risk that the abnormal blood vessels might grow back. If this happens, you might need to repeat the treatment.

Your risks may differ based on your age, general health, and the type of AMD you have. Ask your eye doctor which risks apply most to you.

Ask your eye doctor what you need to do to get ready for laser photocoagulation. Ask your eye doctor if you need to stop taking any medicines before the procedure.

Your eye doctor may want to use special tools to shine a light in your eye and check the back of your eye. You will need to have your pupils dilated (enlarged) for this eye exam. You may need other special tests to get even more information about your eye.

Before the procedure, eye drops will be used to dilate your pupil. It will stay dilated for a few hours after the procedure.

This is an outpatient procedure done in an eye doctor's office. This means you will go home afterward. During a typical procedure:

• You may be given medicine to help you relax. The eye doctor will use anesthetic eye drops and may give you a shot (injections) to make sure you don't feel anything or move your eye.
• Your doctor will put a special type of contact lens on the surface of the eye. This lens helps focus a beam of laser light on the retina using an instrument called a slit lamp.
• The eye doctor will use the laser to seal off the abnormal blood vessels under the macula.
• Your eye may be covered for a little while after the procedure.

Ask your eye doctor about what to expect after your surgery. You will be able to go home the same day. Plan to have someone go home with you after the procedure.

Follow your eye doctor's instructions about eye care and medicine. Your eye may be a little sore after the procedure. But you should be able to take over-the-counter pain medicines as directed. You may need to wear an eye patch or dark glasses for a day or so. Ask your doctor if you should not do certain activities as you recover.

You will need close follow-up care with your eye doctor. They will watch you for complications. The doctor will continue to manage your treatment for AMD. Tell your doctor right away if you have reduced vision. Or if you have more eye redness, swelling, or pain.

Your vision may be blurry after the surgery. Remember that the surgery does often cause an area of new vision loss. In the long term, it may help stop your vision from getting worse.
