I hadn't seen this thread before. I also had PVD about four years ago. I noticed peripheral white arcs of light in the left side of my left eye on a Sunday afternoon. I went to my local Emergency Clinic that evening, thinking it might be the beginning of a retinal detachment. After examining me, the doctor made an immediate appointment for me at the main eye clinic for Southern Alberta, for 8 am on Monday morning!
Luckily the hospital was only 40 minutes away by car. After extensive tests, retinal detachment was ruled out and I was relieved to hear the PVD diagnosis, even though I had never heard of the condition:

I only had the arcs of light and floater symptoms. I didn't have the pulsing eye symptom.
I was told the symptoms would eventually go away, which they did.
