Thank you for posting your query.
There are two kinds of spots caused due to cholesterol deposit, Xanthomas and Cholesterol embolus.
Xanthomas are found On the eyelids while the Choleterol emboli are Found on the retina
Both can regress by lowering the high cholesterol
levels. You need to consult a physician to help you with that.
Though the cholesterol emboli cannot be surgically treated, Xanthomas can be removed surgically.
Do get back to me if you have further queries.
