The retina is the light sensing layer lining the back of the eye. A retinal tear can let fluid seep under the retina and lift it away, called a retinal detachment. A detachment is an emergency that can cause permanent vision loss, but a tear found early can often be sealed with laser before it detaches.

Call (626) 960-3741 the same day if you notice

  • A sudden shower of new floaters, spots or cobwebs
  • New flashes of light, especially at the edge of your vision
  • A shadow or curtain moving across your vision
  • Sudden blurred vision in one eye

We hold same day appointments for these symptoms. After hours, go to the nearest emergency room.

Who is at higher risk

  • Age over 50, when the gel inside the eye commonly separates from the retina
  • High nearsightedness
  • Previous cataract or other eye surgery
  • Eye injury
  • A previous retinal tear or detachment, or a family history of detachment

What we do

A dilated exam of the full retina, including the far edges where most tears happen. Small tears are usually treated with laser to seal the edges, often as a quick office procedure, and we arrange this promptly. Detachments need urgent surgery with a retina specialist, and we coordinate that care.

Are all floaters dangerous?

Most people have a few floaters, and they are usually harmless. What matters is a sudden change: a burst of new floaters, flashes or a shadow. Those need a dilated exam even if the symptoms fade.

Common questions

My new floaters are getting better. Do I still need to be seen?

Yes. A tear can be present even when symptoms improve. Any sudden new floaters or flashes should be checked with a dilated exam.

Is laser treatment for a retinal tear painful?

It is done in the office with numbing drops. Most people feel only mild discomfort and go home the same day.

Can a retinal detachment be prevented?

Not always, but finding and treating a tear before fluid gets under the retina often prevents a detachment. That is why prompt exams for new symptoms matter.
