This is the Allen Dot. It is there to stop in internal light flare. It will
show up on high myopes. Don't remove it!!!

Rule of thumb (My thumb). White spots are on the front lens ( Patient lens),
dark spots out of focus are in the
middle focus lenses and or CCD chip, in focus dark spots are on the field
lens.

Any reason why the Allen dot on our fundus camera should suddenly and
seemingly spontaneously degrade? Large, diffuse spot now in our images,
MOSTLY high myopes, but not always. See attached images.
