Swelling and pain at the outer corner of the eye, with pain also felt when blinking

Swelling and pain at the outer corner of the eye, along with pain when blinking, may be caused by conditions such as hordeolum, acute dacryoadenitis, or trauma, and treatment should target the underlying cause.

1. Hordeolum: Poor eye hygiene can lead to contamination of the oily secretions from the meibomian glands, resulting in inflammation. As directed by a physician, medications such as tobramycin eye drops, levofloxacin eye drops, or chlortetracycline eye ointment may be used to reduce inflammation and relieve swelling and pain.

2. Acute Dacryoadenitis: When the body's immunity is reduced, it becomes more susceptible to viral infections. Infection in the lacrimal gland area may lead to this condition. Antiviral medications such as ribavirin tablets, ganciclovir tablets, or acyclovir tablets may be prescribed to inhibit viral replication and alleviate symptoms.

3. Trauma: If the outer corner of the eye suffers physical impact, it may injure soft tissues and the ocular membrane, leading to pain and swelling. It is recommended to seek medical care at a hospital, where treatments such as cold compresses or surgical wound debridement and suturing may be chosen based on individual circumstances.

In addition, other conditions such as herpes zoster ophthalmicus may also cause similar symptoms. Prompt medical evaluation and syndrome differentiation at a hospital are advised for proper diagnosis and treatment.
