Sudden partial loss of vision.
IDENTICAL pattern of total blackout in part of both eyes. I mean identical throughout the event.
This was 'U' shaped and covered a radial extent of about 20 degrees.
Slightly off center but in identical position in both eyes.
The remainder of the image was normal.
Scintillation of affected area increased minute by minute as the defect enlarged.
It weakened, enlarged, and moved slowly in the same direction in both eyes.
The effect gradually declined over a half hour and disappeared.
I have never had migraine or flashing in the eyes of any kind.
My blood pressure taken last week was 112/70. I am 71 years old, slender, active.
I Used computer in brightly lit room and screen.
Vision normal. Eyes bright-adapted, presumably pupils constricted.
No drug use whatsoever of any kind: no alcohol, non smoker, no others e.g. amphetamine.
I went outside into dark for 2 minutes to move car into driveway, with headlights.
I do not recall any bright lights that I turned away from, just normal house lighting.
Come back inside.
Problem is immediately apparent, significant and distinctive.
My first impression was that I had been hit by a laser as we read about in the news, but this is a housing development in rural Thailand, so I think this is unlikely. It was also too spread-out to be that unless defocused. This lasted far longer than similar very quickly dissipating distortions caused by eye scanning across the sun or a welding torch or extremly bright lighting when pupils open.
