Blepharitis, known in ancient times as “needle stealer”, is also known as “mydriasis”. It is an acute inflammation of the eyelid glands due to invasion by septic bacteria. It is mostly caused by staphylococcal infections, the most common being Staphylococcus aureus. Patients may see localized redness and pain in the upper or lower eyelid, with palpable masses and pressure pain, and in severe cases, enlarged ipsilateral preauricular lymph nodes or reactive bulbar conjunctival edema. If the redness is located on the skin surface and ulcerates on the skin surface, it is called exophthalmos; if the redness is on the conjunctival surface or if the abscess penetrates the conjunctival surface, it is called endophthalmos. Some lumps absorb on their own, while others break down and drain pus. In Chinese medicine, the eyelids are considered to be the meatus of the five chakras, and the spleen is the master of the muscles, so blepharitis is a result of heat in the spleen and stomach and occurs in young adults. It is common to see young people who have a strong Yang body and poor bowel movements, and who are addicted to spicy foods and thick flavors that cause heat to accumulate in the spleen and stomach, causing blepharitis to develop in the meatus. Therefore, we should pay attention to a light diet, avoiding spicy products and eating less high-energy foods such as chocolate, whipped cream, animal products, hamburgers and fried products to keep the bowels open. It is not surprising that some patients do not take this seriously and continue to eat hot pot, so it is not surprising that they have episodes of blepharitis in both upper and lower eyelids, or both, which is called polypoidal blepharitis. Treatment: Before blepharitis suppurates, a hot compress may be applied 2 to 3 times a day to dissipate the inflammation, and oral cleansing herbs or antibiotics may be used to suppress inflammation and apply local antibiotic eye ointment. If the patient has significant eyelid redness and pain and weakness in opening the eyes, a sterilized trigeminal needle may be used to bleed the affected eye ipsilateral or contralateral to the tip of the ear to temporarily relieve eye discomfort; if an abscess has formed, it should be promptly incised and drained. In external blepharitis, the incision must be parallel to the lid margin and consistent with the skin texture; in internal blepharitis, the incision should be perpendicular to the lid margin, consistent with the alignment of the lid glands, and adequately drained of pus. Then, the blepharitis will soon be cured.
