Bottom Line

A new curtain or shadow over vision can mean retinal detachment. Get same-day care from a retina specialist or ophthalmologist.

A dark curtain, veil, or shadow can happen when part of the retina pulls away from the back of the eye. Retinal detachment can cause permanent vision loss without quick treatment 1.

Other warning signs include new flashes, many new floaters, or sudden vision loss. These symptoms need same-day care from a retina specialist or ophthalmologist 2.

If you cannot reach an eye doctor today, go to the emergency room. If face droop, slurred speech, confusion, or weakness happens too, call 911 because that may be a stroke.

What It Can Mean

A curtain symptom is a retina warning until an eye doctor proves otherwise.

  • Retinal tear can cause flashes and floaters.
  • Retinal detachment can cause a dark curtain or shadow 1.
  • Vitreous bleeding can make vision look dark or hazy.
  • Stroke or blood-flow problems can also cause sudden vision loss.

What the Exam Checks

The key test is a dilated retina exam. The doctor looks for tears, holes, bleeding, and detached retina.

If the view is blocked by blood or cataract, an ultrasound may help. Do not wait for the symptom to improve on its own.
