@ainsleigh You'll notice that I added your question to a previous conversation related to similar symptoms. Members like @imallears @lioness @breenmcbee have discussed this topic in the past and may be able to offer support.

May I as if your dermatologist mentioned either calcium deposits or milia? These are two different issues.

I saw an opthamologist and he said I have
blepharitis (you can read about this on Mayo Clinic). We are unfortunately more prone to this as we age. There is no real cure but it has to be managed with warm compresses and artificial tears. There is a procedure (for $250 dollars) called Blephex
which is not covered by OHIP. Hope this info is helpful.
