Ophthalmology? Dermatology? Where should I go?

Right below the eye.. almost on the mucous membrane area, a milia or something similar...

It's a yellow grain...

Lately, I've been especially worried... I think I have crusty eyes...ㅠㅠ

Yes~ I think I had it removed at the ophthalmology clinic before... but my memory is a bit fuzzy.

Do I need to go to the dermatologist?

I'm scared because it's so close to my eye's conjunctiva..ㅠㅠ

Which department should I go to???
