Retinal Tears and Retinal Detachment

A retinal tear can lead to detachment and permanent vision loss. Recognizing the warning signs and getting urgent help matters.

Seek help immediately: A sudden shower of floaters, flashes of light, a dark curtain or shadow, or sudden blurred or missing vision needs urgent eye assessment. Go to an eye emergency service or emergency department. Do not wait for a routine appointment or for the symptoms to settle. Emergency warning signs.

What is happening inside the eye?

The retina is the thin, light-sensitive layer lining the back of the eye. A retinal tear is a break in this tissue. If fluid passes through a tear, it can lift the retina away from the eye wall, causing a retinal detachment. Other detachments can result from pulling by scar tissue or fluid collecting beneath the retina. Retinal detachment overview.

Symptoms and risk factors

Flashes and floaters can have several causes. You cannot tell at home whether they come from an uncomplicated change in the eye’s gel or a retinal tear. New symptoms need examination even if there is no pain. A spreading shadow or missing area of vision is especially concerning. Symptoms.

Risk is higher with severe short-sightedness, previous detachment, an affected close relative, eye injury and some previous eye operations. Diabetic eye disease can cause scar tissue that pulls on the retina. A retinal problem can still occur without a known risk factor. Risk factors; diabetic scarring.

How it is diagnosed

An eye specialist examines the retina through a widened pupil, including its outer edges. The assessment may also involve ultrasound or other imaging when needed. Explain exactly when the symptoms began and whether they are increasing. The findings determine whether treatment is needed and how urgently it should happen. Diagnosis.

Treatment and recovery

A tear may be sealed with laser or freezing treatment to reduce the risk of detachment. These treatments create a seal around the break. A detached retina often needs surgery, which may involve removing the eye’s gel, placing a supporting band around the eye, or using a gas bubble. The operation depends on the detachment. Treating tears; surgical options.

Recovery and the amount of vision regained vary. Follow the surgeon’s instructions about eye drops, positioning, activity and follow-up. Seek help from the treating hospital urgently if pain, redness or vision worsens after surgery. Recovery.

If there is a gas bubble in your eye: Do not fly until your surgeon confirms it is safe. Tell every healthcare professional treating you about the bubble, because nitrous oxide used for anesthesia or pain relief can dangerously increase eye pressure. Gas-bubble precautions.
