Recognize an emergency
Retinal Detachment
The retina is the light-sensitive tissue at the back of the eye. When it pulls away from its normal position, it can threaten vision and needs immediate medical evaluation.
Sudden warning signs
- A sudden increase or shower of new floaters (spots, specks, or cobweb-like shapes)
- Flashes of light in one or both eyes
- A dark or translucent shadow or curtain moving across part of your vision
- Sudden worsening or loss of vision
A small detachment may not cause noticeable symptoms. A sudden change should be assessed urgently even if it is painless.
Why acting quickly matters
Without prompt treatment, a detachment can worsen and cause permanent vision loss. Only an eye care professional can diagnose the problem and determine treatment. This page is not a substitute for emergency assessment.
