The corner of the eye is mostly a limited nodule on the eyelid or eyelid, depending on whether there is significant redness, swelling, and pressure pain. If it is a limited nodule with an acute onset, redness, swelling, and pressure pain, consider it to be an inflammation of the lid gland duct, which is commonly known as a pinhole. In this case, you can apply a local cold compress, order eye drops with antibiotics, one drop each time, 3-6 times a day, with oral Chinese medicine to clear the heat and fire and detoxify the eye, and the symptoms found early can disappear. If it has been too long and has formed pus, it needs to be punctured or excised in the ophthalmology to drain the pus. If this nodule has no obvious pressure pain, relatively clear border, hard texture and good mobility, it is considered that it may be a scattered granuloma, which has formed a cystic bag package requiring surgical treatment in ophthalmology.
