I have GCA question.
Flashes of light (streaks) when quickly looking to my right.

I was dx’d with PMR in October of 2025, about 10 months ago.
It is now mid-August, I take Kevzara and have tapered Prednisone down to 1mg/day.

I had a temporal biopsy done in May of 2026, (left temple) the report was Negative for GCA.
No reason given for the tender scalp, which was why the biopsy.

4 days ago , I was caused to be awake until early morning hours before finally getting to bed.

3 days ago, in the evening (darkness) I started seeing streaks of light, in the right periphery of my right eye.
My PMR aches were elevated a bit and my E-SED & CRP (taken coincidentally the day before) had just come back slightly elevated. Hmm. I took 2mg of Prednisone that first day and the aches have subsided. But in the evenings, I’m seeing the streaks of light still.

Has anybody here, with GCA. Had the flashes of light experience, and/or is it a symptom of GCA?

Thanks in advance.
