Lupus Erythematosus: Cotton Wool Spots
Cotton Wool Spots
Cotton wool spots are the most common ophthalmic manifestation of lupus erythematosus. They are not, of course, specific for this illness, but in the proper setting, they may be the first clue to its presence.
If the diagnosis is known, newly appearing cotton wool spots suggest activation of the disease and raise the suspicion of central nervous system involvement. They do not usually interfere with vision.

What to do?
Cotton wool spots help confirm the presence of microvascular complications of lupus. A new appearance of spots is a sign that the disease is activating and may affect the central nervous system. More intensive treatment is needed.
