I had the dreaded black disc in dim light , which disappears in an instant . Dim light only . For years , as I have gotten older ( I am 68) A small area. Central vision.
The Institute did a full work up with micro photography. Retina, optic nerve, macular : all good.
NO problems. No disease , no damage.
They will be doing a lens implant , both eyes , due to a cataract.
Peripheral Iridotomy done ten years ago for anatomical narrow angle . Lazers ( holes ) all good and functioning.
It's not the macular ( the black disc.)
