I've been attending a retina clinic at Moorfields every five or six months to monitor hard and soft drusen. Last July's visit did not reveal any change or damage to the retina. About three weeks ago I became aware of a small blotch just off-centre of focus in my right eye that was like an after-image of a sun-flash, which seemed to refresh itself in blinking like an after-image, but which didn't fade and go away. A day later, looking at the Amsler grid with my right eye, I saw a wiggle in a line of the box just left and up of the central dot. A couple of days later, when this had not disappeared, I went to Moorfields A&E. A scan showed no abnormalities, no bleed and no fluid. The doctor thought that the wiggle could have been produced by one of the drusen, but was puzzled by the after-image effect, and wondered if it could be an optical migraine. I do get optical migraines, and had thought it could be connected, but it doesn't behave like the beginning of a migraine, which starts right on the focal point and extends for about half and hour and then disappears.
Does anyone else have this 'after-image' effect? Does it coincide with a distortion in the Amsler grid?
Today, looking at the grid, it is more than just a wiggle in one line, but a kind of small transparent bubble. I shall keep monitoring, perhaps I should go again to A&E? Does a bleed happen without it being visible on a scan?
I am so depressed by this. I am trying to design our Christmas card, and what with Brexit and this I am at a loss to know what to draw, and even less confident that I shall be able to complete it.
