Retina
Floaters, flashes and shadows
1 min read Dr. Gerardo Ledesma Gil
Retina, vitreous and macula
A sudden burst of them, or a shadow moving in from the side, should not wait for your next visit: it calls for a prompt retina exam.
Floaters are shadows cast by the gel that fills the eye, and with the years almost everyone sees a few. Having them for a long time, unchanged, is usually part of the scenery. What changes the conversation is when they show up all at once.
When not to wait
- Many new floaters all at once, especially if there were none before.
- Flashes of light, like lightning, even with your eyes closed.
- A curtain or shadow coming in from one side and advancing.
- Loss of vision in part of your field, however small.
Any of those four calls for a prompt dilated retina exam. Most of the time there will be nothing to treat, and that is also an answer worth having the same day.
