Retinal "ink blots" when awaking in a dimly lit room

There are some region of my retinas that are less light sensitive than others and these appear as sort of "ink blots" when I first open my eyes in the morning in a dimly lit bedroom. They disappear after my eyes have been open for a bit. The affected regions can get both larger and smaller over a few days. When smaller, there is a central blot with smaller blots on the periphery. When larger the central blots merges with many of the other blots and a new blot may appear to the side of the original blots. This expansion and contraction of the affected areas has happened multiple times over the past two years and I have been trying to discern what is the cause. It doesn't seem to be dietary and I have been taking AREDS vitamins consistently. The blots got larger while I weas vacationing but gradually got smaller after I retuned home. I have macular degeneration but this variability seems to be not normally associated with macular degeneration as my ophthalmologist had never heard of it.
