We need to see a doctor to determine what the cause of the enlargement is. If it is accompanied by itchy eyes and sneezing, then it may be due to conjunctival edema caused by allergies, resulting in a swollen tear trough, which can be treated with anti-allergy medication. If it is accompanied by redness, increased discharge, and itchy eyes, the tear folds may be enlarged due to conjunctivitis, and anti-inflammatory and anti-infective treatment should be given to address the cause. If the lacrimal caruncle is spherical, irregular or cauliflower-shaped, it may be a tumor in the lacrimal caruncle area, which may require surgical removal of the tumor, followed by an examination to determine the nature of the tumor lesion. If there is no other reason for the enlargement of the lacrimal caruncle, the lymphatic drainage of the conjunctiva may be obstructed, resulting in a simple enlargement of the lacrimal caruncle, which may not require special treatment for the time being.
