Macrophthalmia is clinically known as epiphora. The lid gland is located deep in the eye tissue and opens at the lid margin. Staphylococci enter the gland through the opening in the lid margin and cause an infection called blepharitis. Depending on the site of the infected glandular tissue, it is classified as internal and external blepharitis. If the abscess is untreated, the pus will drain in 2-3 days after it breaks on its own; if the inflammation remains uncontrolled for a long time or if the abscess is large, a surgical incision is needed to place a drainage strip to promote drainage, which takes about 3-5 days; however, if the break is small, it may cause recurrent disease and requires medication, which takes about 7 days to drain. The initial manifestation of external blepharitis is a feeling of resistance or swelling when blinking. The pain gradually increases as the disease progresses, the eyelid becomes locally edematous and congested, and hard nodules can be felt near the lid margin. After a few days the hard nodules gradually soften and yellow pus heads appear at the roots of the eyelashes. Once the accumulated pus has penetrated the skin and drained outward, the redness disappears and the pain disappears. Once the skin is pierced and the pus is drained outward, the redness disappears and the pain disappears. The causative bacteria are so virulent that multiple pus spots may form, with systemic symptoms such as chills and fever. Squeezing is not allowed until the abscess forms to avoid spreading the infection. When the inflammatory reaction is intense, systemic antibiotics are needed to combat the infection, such as oral amoxicillin as prescribed by the doctor to accelerate healing. During this period, patients should pay attention to eye hygiene, keep the local area dry, avoid direct contact with the affected area by hand, and remove the secreted pus in time with sterile cotton swabs or clean gauze to avoid further spread of inflammation.
