Physical therapy for dry eyes generally consists of hot compresses and lid gland massage. The ducts of the normal lid gland are photographed on video as a single, evenly spaced, straight duct, like a white comb, with the ducts in the upper lid being thin and long and those in the lower lid being relatively thick and short. When this regular white duct is clogged, dilated, distorted, or even partially missing, the lid glands secrete abnormal amounts of oil, either qualitatively or quantitatively, just as if our pores were clogged, and a hot compress with massage is needed to unclog the duct. Hot compresses and massage Hot compresses are usually applied with a hot towel at 40-45 degrees, gently closed and placed on the eyelid for 10-15 minutes, followed by a few minutes of lid gland massage, which is performed by pulling the eyelid as tight as possible and pushing in the direction of the glandular ducts with moderate force, as it is easy to involve the cornea when operating on your own, so it is recommended to go to a regular hospital to be operated by a doctor and nurse. After the massage, clean the root of the lid margin, apply a hot compress as much as possible 1 to 2 times a day, and massage once a month.
