Thank you for the response.
I agree with Dr. Riaz that dry eyes
would be the first thought. It appears your ophthalmologist in June had a similar diagnosis with likely steroid eye drops and lubrication. As you mentioned, you do not have the typical symptoms of dry eyes besides the eyelid swelling, but this can still be a possibility. The mucous discharge in the morning is very suggestive of overnight drying. I recommend you use a lubricating ointment in your eyes before bedtime.
Eyelid swelling can also be an early sign of thryoid eye disease. This is commonly associated with hyperthyroidism (Graves disease
). If you haven't been checked for that in the last 1-2 years, I would recommend you ask your family physician to check a TSH, T4, and TSI.
Another possibility to consider would be blepharochalasis syndrome
. This syndrome has an unknown cause but is characterized by repeat bouts of upper eyelid swelling and resulting thinning and stretching of the upper eyelid skin. As the link above describes, it starts in the teen years, so this would be less likely for you.
