A retinal tear occurs when the retina develops a break, often as the gel inside the eye naturally changes and pulls away. Fluid can pass through a tear and separate the retina from the wall of the eye, causing a retinal detachment. Warning symptoms may include sudden flashes, many new floaters, or a shadow or curtain moving across the vision.
Some retinal tears can be sealed with laser treatment or freezing therapy before a detachment develops. A retinal detachment usually requires a procedure or surgery, with the approach tailored to its location and severity. Prompt diagnosis matters because earlier treatment may improve the chance of preserving vision.
