Hi,
I occasionally on getting ready to sleep at night, with room light on and maybe hall light still on, see something resembling a slow refresh rate/vertical scan on an old crt monitor. It's not bright, but just enough to notice. Is this the "flashing" the opthamologist told me to watch for after a repair on a small retinal tear? I previously had a vitreous hemmhorage which cleared up by itself 90% without vitrectomy after a couple years.
