Arc of Light in Dark Room

i would call my doctor and have this checked right away. Without being an alarmist I think you need to be sure it isn't a retina issue. I had a similar issue many years ago that was diagnosed as the beginnings of a detached retina. I saw a specialist and we did "watchful waiting" and it actually healed, however I think you should see your eye doctor asap.

Greg if this appears only at night it is likely your pupil is dilating beyond the IOL and you are seeing edge of IOL. Have you asked your surgeon about it?

Definitely see your doc. Because of retinal issues that I had, it was drilled into me that any floaters, lights, etc, are not necessarily cause for alarm, but should be checked out. It saved my bacon a few weeks ago when I noticed a little shadowing/transparent curtain-ish effect at the very outside of one eye. One immediate appointment later, I was undergoing argon laser treatment to strengthen the very thin retinal wall that had just started to detach. No, things aren't perfect, but my vision is still 20/20. As the doc said, better to catch it now than later when it could have been so much worse.

Please let us know how you're doing.

Hello, as mentioned by a couple others, could be a retina issue. Could just be posterior vitreous detachment, but could be more. If you call a retina specialist, they will see you right away. Good Luck.

I really appreciate all of the replies. My health care provider is Scripps in San Diego. I looked online and found that they have 2 doctors who specialize in retinal and vitreous disease.

I presume that I would not want to call the doctor who did my cataract surgery as he does not specialize in retinal issues. They open up at 8 a.m., so I hope to get in to see a doctor on Monday. Thank you for all of your help.

hi there. just to be sure i'd get it checked out. my guess is your pupil dilates in the dark and you are getting a flash off the edge of IOL. but, better safe than sorry. let us know:)

Boy, I can be a dufus! Greg, try this very simple test to see if it's the edges of the IOL that you see: go into a medium-lit room (make sure a lamp or overhead light is on). Look in a direction that gives you the arc of light. Now, look directly at the lamp for 2 or 3 second and then look back again in the direction where you saw the arc of light. If it disappears, then it's probably the edges of the IOL. If you're "lucky" like me and have large eyeballs (high myopic) this might explain the arc (because of the size, when in a dark room, the pupils enlargen to the point that we can see the edges of the IOL. Slightly irritating, but looking at a light source makes it immediately disappear. Simple fix and it eventually becomes automatic.) Regardless of the results, be sure to see the doc.

I just got back from the doctor's office. He dilated my eye and looked at it. As it turns out, there was nothing wrong. He told me to call him if I should get more floaters or light should become larger or brighter. He thinks that the condition will eventually go away.

Thank you for everyone who offered insight into my problem. I now feel a lot of relief after having it checked out.

great news! Glad you got checked out.
