What Is a Jet Stream Retinal Tear?

A jet stream retinal tear is a linear, sharply oriented tear that forms when strong vitreous traction pulls the retina in a focused direction. This pattern often occurs in areas of firm vitreoretinal adhesion. People may notice sudden flashes, floaters, or a dark curtain if detachment begins. The tear's narrow shape increases the chance of fluid passing beneath the retina. Prompt detection reduces the risk of progression.

Causes of a Jet Stream Retinal Tear

Age-related vitreous separation is the most common cause. Areas of tight vitreous attachment create focal traction. High myopia increases vulnerability. Trauma can also trigger tearing. Identifying risk factors supports follow-up planning.

Symptoms of a Jet Stream Tear

People may see sudden flashes of light. New floaters often appear. A peripheral shadow may develop. Visual clarity may decline if detachment begins. Symptoms often appear abruptly.

How It Is Diagnosed

Dilated fundus exam reveals the tear's linear configuration. Scleral depression helps view peripheral regions. OCT may show early detachment. Ultrasound is used if media are cloudy. Diagnosis guides urgent treatment.

Treatment for a Jet Stream Tear

Laser retinopexy seals the tear's edges. Cryotherapy may be used in selected cases. Once treated, many tears stabilize. Follow-up checks for new traction. Early care prevents detachment.

Frequently Asked Questions About Jet Stream Retinal Tears

Is this dangerous?

It can lead to detachment if untreated.

Can both eyes be at risk?

People with strong traction in one eye may have risk in the other.

Do flashes go away?

Flashes decrease as traction settles.

When should I seek care?

Seek care for new floaters or shadows.
