What could be the reason for persistent redness in pink eye that won't go away?

Generally, persistent redness in conjunctivitis (pink eye) may be related to poor eye habits, incomplete treatment, concurrent keratitis, concurrent conjunctivitis, or trachoma. Targeted interventions can be taken accordingly. If any of the above conditions exist, it is recommended to seek timely medical treatment. Specific details are as follows:

1. Poor Eye Habits

Prolonged use of electronic devices, lack of rest, and insufficient sleep can lead to eye fatigue and dryness, worsening conjunctivitis and causing symptoms to persist. It is important to practice proper eye use and ensure adequate rest for the eyes.

2. Incomplete Treatment

If conjunctivitis is not fully treated, pathogens may not be effectively controlled and inflammation may not be completely resolved, leading to persistent or recurrent symptoms. Patients should complete the full course of treatment as directed by a physician, ensuring medications are taken correctly and on schedule.

3. Concurrent Keratitis

Keratitis is an inflammation of the corneal surface, often caused by infection, injury, or other factors, and commonly accompanied by eye pain, burning sensation, photophobia, and tearing. If left untreated, keratitis can continuously irritate the cornea, making it difficult for conjunctivitis symptoms to resolve. Follow medical advice to manage the condition with medications such as methylprednisolone tablets, dexamethasone acetate tablets, or levofloxacin hydrochloride eye drops.

4. Concurrent Conjunctivitis

Conjunctivitis refers to inflammation of the conjunctiva, with typical symptoms including redness, swelling, increased eye discharge, and blurred vision. Without prompt and effective treatment, ongoing eye irritation may cause conjunctivitis symptoms to persist. Medications such as chloramphenicol eye drops, ganciclovir eye drops, or ofloxacin eye drops may be used as directed by a physician.

5. Concurrent Trachoma

Trachoma is a type of conjunctivitis caused by *Chlamydia trachomatis*, which may lead to eye redness, foreign body sensation, increased secretions, and possibly conjunctival concretions. When coexisting with conjunctivitis, it may result in continuous ocular irritation due to infection. Follow medical guidance to manage symptoms with medications such as houttuynia cordata eye drops, chlortetracycline hydrochloride ointment, or minocycline hydrochloride capsules.

In daily life, avoid frequently rubbing the eyes to prevent harm to eye health.
