I am considering lower blepharoplasty, but I am becoming more and more concerned about possible chemosis. I have rosacea (ocular and skin). My ocular surgeon assured me it is not a problem, but I have seen some scientific papers talking about possible increased risk of chemosis in patients with rosacea. I am 35, caucasian woman. Is my doctor being truthful? Is there anything one can do to decrease risk of chemosis?
