What does it mean when you see a lightning bolt in your eye?

Flashes of light are typically seen as lightning bolts or streaks of bright white light in the peripheral vision. As the vitreous separates from the retina, it may tug on the retina triggering the flashes of light. These can be caused by dangerous interruptions in blood flow, abnormal fluid in the retina, or migraines.
A.

Why do I see a flash of light in the corner of my eye?

Causes for flashes and floaters. Flashes and floaters can be caused by: Detachment of the jelly-like “vitreous” from the retina. Detachement of the innermost light-sensitive layer of the eye is the most common cause of floaters and flashes.
  • Do flashers go away in the eye?

    Flashes and floaters not caused by a retinal tear or detachment are harmless. They may never go away completely, but they tend to become much less noticeable with time. However, if the floaters or flashes are caused by retinal tears or detachment, you could lose your vision if treatment is not provided.
  • Are flashes in vision normal?

    Eye flashes result from thickened vitreous gel pulling and rubbing on the retina, causing visual effects that look like lightning streaks or light flickers. These flashes may appear off and on for a few weeks or months, but normally fade over time.
  • How do you repair a detached retina?

    One method of retinal detachment repair is pneumatic retinopexy. In this procedure, a gas bubble is injected into the eye. The bubble presses against the detached retina and pushes it back into place. A laser or cryotherapy is then used to reattach the retina firmly into place.
B.

Why do I see flashes of light in my peripheral vision?

Small arc-like momentary flashes of light in the peripheral vision are commonly experienced during vitreous separation. The vitreous pulls on the retina which makes one think they are seeing a light but it is caused by movement of the retina. Rarely flashes are associated with a tear in the retina.

  • What does it mean when you see flashing lights in your peripheral vision?

    Flashes of light in your vision come from inside your eye or brain. They are not caused by lights or anything else outside of your body. Most flashes happen when the vitreous gel inside the eye shrinks or changes, pulling on the retina (the light sensitive lining of the eye).

C.

Why do I see flashing lights in my peripheral vision?

Retinal Tear. A tear in the retina can occur with vitreous detachment (see discussion above), with trauma or eye injury, or in areas at risk for a retinal tear, such as "lattice degeneration". The symptoms of a retinal tear usually are of a flash of light in the peripheral vision followed by floaters.
  • What is a flash in the eye?

    Flashes are sparks or strands of light that flicker across the visual field. Both are usually harmless. But they can be a warning sign of trouble in the eye, especially when they suddenly appear or become more plentiful. A floater is a tiny cluster of cells or fleck of protein lodged in the vitreous humor.

  • What is the cause of ocular migraines?

    Ocular migraines can develop with or without the accompanying pain of a classic migraine. During an ocular migraine, or migraine with aura, you may see flashing or shimmering lights, zigzagging lines, or stars. Some people describe psychedelic images. It may also cause blind spots in your field of vision.
