What causes milk spots ?
‘Milk spots’ are relatively common and are actually small cysts in the skin, which is why you cannot squeeze them as there is no pore to push them through. If they are very small, it is best to leave them alone. If there is a particularly large one, then this could be pierced with a sterile needle and the contents of the cyst then gently expressed but again it would not be advisable to tackle any cysts within close proximity to the eye itself or lids as you could do damage. They will often resolve spontaneously over a period of time. There is no specific treatment to prevent them. You should see a doctor if you really want to have them removed.
