Floaters are usually harmless and although initially annoying, tend to become less noticeable with time. Flashing lights may be seen either alone or with floaters, and are usually caused by the vitreous gel tugging on the retina during a posterior vitreous detachment.

Is it normal to see a flash of light from the retina?

Some changes to the vitreous and retinal tugging are actually fairly normal. Most people experience this as seeing a little flash of light. However, a retinal detachment happens when the vitreous tugs so hard on the retina that the retina moves away from the eyeball.

Can a detached retina cause loss of vision?

If too much fluid gets in between the eyeball and retina, this can cause retinal detachment. Once detached, the retina can no longer do its job of sending light signals to the brain, which can cause a loss or alteration of vision.

Initial symptoms of retinal detachment commonly include the sensation of a flashing light (photopsia) related to retinal traction and often accompanied by a shower of floaters and vision loss.

What causes flashes of light in the retina?

Most commonly the inflammation is in the front of the eye, but on occasion, there can be types of inflammation affecting the retina. Symptoms can include flashes of light. The best way to diagnosis retinal or retinal vascular inflammation is with a dilated eye exam.
