Flashes and Floaters – 閃光和飛蚊症

 

Should I worry about flashing lights or floaters that are new?

Yes, sudden onset of floaters or the presence of flashes of light may be a symptom of something more serious.

What causes flashing lights and floaters?

Floaters are commonly seen by many people as flies, spots, cobwebs or hairs. They are due to particles floating in the vitreous (jelly inside the eye) casting a shadow on the retina. It is normal to have some floaters, but the sudden onset of new floaters or the presence of flashes of light may be a symptom of something more serious.

What should I do if I experience flashing lights or new floaters?

It is important that your retina be examined to make sure that there are no retinal problems needing treatment such as a retinal tear, a retinal detachment or a vitreous haemorrhage.
