The method of incision for meibomian gland, also known as blepharitis, needs to be chosen based on the type of blepharitis. For external blepharitis, the incision is made on the skin surface, parallel to the lid margin; for internal blepharitis, the incision is made on the conjunctival surface, and the incision is made perpendicular to the lid margin. In external blepharitis, an infection of the sebaceous or sweat glands of the eyelid, the swelling is small and superficial, and the incision for incision and drainage is made parallel to the lid margin to minimize scar formation after abscess formation. Internal blepharitis, an infection of the eyelid palpebral glands, has extensive and deeply located swelling; after abscess formation, incision and drainage is made at the conjunctival surface and oriented perpendicular to the lid margin, which avoids injury to the excessive Meibomian gland ducts. Squeezing of the mass should be avoided until the abscess has formed, as the eyelids as well as the facial veins do not have venous valves, and squeezing the mass may lead to intracranial infection with serious consequences.
