Retinal Detachment

As the premier retina specialists in the Northwest, Proliance Retina provides medical and surgical treatments of the retina, macula and vitreous, including Retinal Detachment.

What is a Retinal Detachment?

The retina is a nerve layer at the back of your eye that senses light and sends images to your brain. An eye is like a camera. The lens in the front of the eye focuses light onto the retina. You can think of the retina as the film that lines the back of a camera.

A retinal detachment occurs when the retina is pulled away from its normal position. The retina does not work when it is detached. Vision is blurred, just as a photographic image would be blurry if the film were loose inside the camera. A retinal detachment is a very serious problem that almost always causes blindness unless it is

What causes Retinal Detachment?

A clear gel called vitreous fills the middle of the eye. As we get older, the vitreous may pull away from its attachment to the retina at the back of the eye. Usually the vitreous separates from the retina without causing problems. But sometimes the vitreous pulls hard enough to tear the retina in one or more places. Fluid may pass through the retinal tear, lifting the retina off the back of the eye, much as wallpaper can peel off a wall.

The following conditions increase the chance of having a retinal detachment:

  • Nearsightedness;
  • Previous cataract surgery;
  • Glaucoma;
  • Severe injury;
  • Previous retinal detachment in your other eye;
  • A family history of retinal detachment;
  • A weak area in your retina that can be seen by your ophthalmologist.

These early symptoms may indicate the presence of a retinal detachment:

  • Flashing lights;
  • New floaters;
  • A shadow in the periphery of your field of vision;
  • A gray curtain moving across your field of vision.

These symptoms do not always mean a retinal detachment is present; however, you should see your ophthalmologist as soon as possible. Your ophthalmologist can diagnose retinal detachment during an eye examination in which he or she dilates (enlarges) the pupils of your eyes. Some retinal detachments are found during a routine eye examination.

Only after careful examination can your ophthalmologist tell whether a retinal tear or early retinal detachment is present.

What is the treatment for a Retinal Detachment?

Retinal Tears
Most retinal tears need to be treated with laser surgery or cryotherapy (freezing), which seals the retina to the back wall of the eye. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. Treatment usually prevents retinal detachment.

Retinal Detachments
Almost all patients with retinal detachments require surgery to return the retina to its proper position.

Types of surgery
There are several ways to fix a retinal detachment. The decision about which type of surgery and anesthesia (local or general) to use depends upon the characteristics of your detachment. In each of the following methods, your ophthalmologist will locate the retinal tears and use laser surgery or cryotherapy to seal the tear.

Scleral Buckle
This treatment involves placing a flexible band (scleral buckle) around the eye to counteract the force pulling the retina out of place. The ophthalmologist often drains the fluid under the detached retina, allowing the retina to settle back into its normal position against the back wall of the eye. This procedure is performed in an operating room.

Pneumatic Retinopexy
In this procedure, a gas bubble is injected into the vitreous space inside the eye. The gas bubble pushes the retinal tear closed against the back wall of the eye. Your ophthalmologist will ask you to maintain a certain head position for 24 hours following the procedure, then return to the office the next day. If the retina has reattached, laser retinopexy or cryotherapy will be performed. The gas bubble will gradually disappear. This procedure is often done in the ophthalmologist’s office.

Vitrectomy
The vitreous gel, which is pulling on the retina, is removed from the eye and usually replaced with a gas bubble. Your body’s own fluids will gradually replace the gas bubble. Sometimes vitrectomy is combined with a scleral buckle.

After surgery
You can expect some discomfort after surgery. Your ophthalmologist will prescribe any necessary medications for you and advise you when to resume normal activity. You will need to wear an eye patch at night for the first week.

Flashing lights and floaters may continue for a while after surgery.

If a gas bubble was placed in your eye, your ophthalmologist may recommend that you keep your head in special positions for a time.

Do Not Fly In An Airplane Or Travel At High Altitudes Until You Are Told The Gas Bubble Is Gone!
A rapid increase in altitude can cause a dangerous rise in eye pressure.  A change of eyeglasses is often helpful after several months.

What are the Risks of Retinal Detachment Surgery?

Any surgery has risks; however, it’s also important to consider that an untreated retinal detachment usually results in permanent severe vision loss or blindness.

Some of the surgical risks include:

  • Infections
  • Bleeding
  • High pressure in the eye
  • Cataract

Most retinal detachment surgery is successful, although a second operation is sometimes needed. If the retina cannot be reattached, the eye will continue to lose sight and ultimately become blind.

Will your vision improve?
Vision may take many months to improve and in some cases may never return fully. Unfortunately, some patients do not recover any vision.

The more severe the detachment, the less vision may return. For this reason, it is very important to see your ophthalmologist at the first sign of any trouble.
