Retinal Tears

​

A retinal tear is a small break in the retina — the thin, light-sensitive tissue lining the back of the eye. While a retinal tear may not cause immediate vision loss, it is a serious condition because it can allow fluid to pass underneath the retina, leading to a retinal detachment if not treated promptly.

Early detection and treatment of retinal tears can often prevent vision-threatening complications.

 

What Causes Retinal Tears?

The most common cause of retinal tears is age-related changes in the vitreous, the gel that fills the eye. As the vitreous shrinks and separates from the retina — a process called posterior vitreous detachment (PVD) — it can tug on the retina. In some areas, this traction is strong enough to create a tear.

Other risk factors include:

• High nearsightedness (myopia)
   

• Eye trauma or injury
   

• Prior eye surgery (especially cataract surgery)
   

• Family history of retinal tears or detachment
   

• Lattice degeneration (thinning of the peripheral retina)
   

• Previous retinal tear or detachment in either eye
   

 

Symptoms

Retinal tears are often painless, but symptoms can appear suddenly and should never be ignored. Common warning signs include:

• Sudden flashes of light, especially in peripheral vision
   

• New floaters or a sudden increase in floaters
   

• A shadow or dark area in part of the visual field (may indicate progression to detachment)
   

• Blurred or decreased vision
   

Any new flashes or floaters warrant prompt evaluation by an eye care professional.

 

How Retinal Tears Are Diagnosed

Retinal tears are diagnosed during a dilated retinal examination, which allows the retina specialist to carefully examine the peripheral retina. Additional tools may include:

• Wide-field retinal imaging
   

• Ultrasound if the view is obscured by blood or media opacity
   

Early diagnosis is key to preventing retinal detachment.

 

Treatment Options

​

Laser Treatment (Laser Photocoagulation)

• A laser is used to create small burns around the tear
   

• These burns form a scar that seals the retina to the underlying tissue
   

• The procedure is typically performed in the office and is usually quick and well tolerated
   

Cryotherapy (Freezing Treatment)

• A freezing probe is applied to the outside of the eye over the tear
   

• Often used when laser treatment is not feasible
   

Both treatments are highly effective at preventing progression to retinal detachment when performed early.

 

After Treatment

Following treatment, patients are usually advised to:

• Avoid strenuous activity for a short period
   

• Monitor for new symptoms
   

• Attend follow-up visits to ensure proper healing
   

Vision may be temporarily blurry after treatment, but most patients resume normal activities quickly.

 

When Is Surgery Needed?

If a retinal tear progresses to a retinal detachment, more extensive surgical repair — such as vitrectomy, scleral buckle, or pneumatic retinopexy — may be required.

 

Prognosis

When treated early, retinal tears generally have an excellent prognosis, with a high success rate in preventing retinal detachment. However, new tears can develop, so ongoing monitoring is important.

 

When to Seek Immediate Care

Seek urgent eye care if you notice:

• New or increasing flashes
   

• Sudden onset of floaters
   

• A curtain or shadow in your vision
   

Prompt treatment can be sight-saving.
