White points (stars) are in spiral patterns, is that it? That image is always with me, when my eyes are closed and I am focused on them. The image is very vivid, and it was very scary at first, but I asked an eye doctor(I don't know how to say it in English) and he sad that this is normal reaction, when you try to look with your eyes closed, especially after looking at bright light. I hope this helps. with regards, Nenad
