Red bump on incision line 2 weeks after double eyelid surgery, should I be concerned? (photos)

Thank you for your question. Your photos and history are suggestive of a suture granuloma. This can be removed in clinic with an easy procedure if it does not go away on its own. Other possibilities include: 1) hypertrophic (abundant) scar tissue which would also be expected to improve with time and can be treated with in office injections (5FU or kenalog steroid) and massage or removal, 2) atypical mycobacterium- a very rare eyelid infection that can presents a few weeks after surgery. I do not think your history or photos are suggestive of atypical mycobacterium so please do not worry about this, however it is important to have your surgeon take a look at the bump so they can treat it appropriately. I think your lid crease looks great and you will heal beautifully with treatment of the bump. 

This could have occurred for a number of reasons - it could be the beginning of a keloid scar or it could be a reaction to the stitching used. You should return to your original surgeon for their opinion on this.

From your history and your photos, sounds like the red bump can be a suture granuloma/ suture abscess, which is inflammation/infection caused by the retaining suture or an internal suture that was used to anchor the double eyelid crease.  You should keep the area clean, refrain from wearing any eye make up for now and follow up with your surgeon as soon as you can.  If treated properly, it should not affect the final outcome.  Goretti H.
