Can a prolonged chalazion cause long-term astigmatism in adults?

Question

My upper left eyelid developed a chalazion five months ago which was causing irregular astigmatism. After several visits with my ophthalmologist, my chalazion has reduced in size and the vision has slightly improved but has not completely resolved. If I continue conservative treatment, how long will it take for the chalazion to resolve and will my left eye develop permanent astigmatism if the lesion stays there longer? I want to avoid minor surgery due to the possibility of having it reoccur.

Yes, Chalazion can cause astigmatism if it is of a large size , especially on the upper eyelids. They can change the shape of cornea. But, it is reversable once removed.

Mark L. Mazow, MD, FACS · Answer

It is possible for a chalzion to cause  astigmatism due to pressure on the cornea. Not all chalazia will resolve with conservative treatment. After five months much of the inflammatory component may have turned to solid scar. Excision may be the only option if you want it resolved. You should consult with your Ophthalmologist or an Oculoplastic surgeon.

Great question! Chalazia can cause astigmatism when they are so big that they deform the cornea.  Once the chalazion is removed or has resolved the induced astigmatism should get better.  Chalazia can be surgically excised, injected with steroids, or conservatively with warm compresses and drops.
Best of luck!
