I use the 450 plus also, and that artifact seems to be the nature of the beast, 
the baffle that is meant to avoid reflections, worse with darker fundii , 
myopes, smaller pupiks, and cataracts.... if you have a patient with several of 
those qualites, it gets really noticeable.
You can try reseating  the filters to be sure the are all squarely seated in 
position. .especially the magnification lever.
The docs hate it, don't like having to mentally dismiss it as an artifact. I 
try to have the patient look a hair off to the side or up or down n to displace 
it out of the fovea, or area being examined.
It also makes for lousy montages, and trying to photoshop them out makes for a 
manipulated image, a no no in medicine.
When we next have our Preventative Maintenance, I always ask for them to try to 
calibrate the lenses and sensors to minimize it. Lack of calibration is a 
factor in how noticeable it is.

Looking for a used RetCam for some animal experiments.  Can acquire just head 
and one objective lens.

Nancy,

Despite what Zeiss says, it is probably the camera, and not your imagers.
I have not used the FF-450, but if you posted a few examples, perhaps
some Optimal FF-450 users out there will have some ideas.

Yup,

hard to tell without seeing the artifacts.

Most likely an internal misalignment of the optics, from the description
A scratch on the objective lens can look like that also, but you replaced the 
lens
I would have checked the internal optics first
