Thank you for the reply. They mentioned it when I went to the optometrist and said that the OCT scan would be able to detect it. Thankfully the scan was clear both times so I don’t think it’s that.

I just tried the test you mentioned—I don’t see any flashing lights. I do get “double images” though, but only when looking at bright lights and then looking away from them quickly.

The doctor I saw in the ER (second time around) referred me to an ophthalmologist, but the wait is over three months. He said he wasn’t concerned because the OCT scans were clear.
