What causes wind-heat red eye?

In general, "wind-water eye" refers to acquired nasolacrimal duct narrowing or obstruction, which may be related to physiological factors, trauma, lacrimal tract infections, dacryoadenitis, or canaliculitis. Patients are advised to follow medical advice for symptomatic treatment. Specific analyses are as follows:

1. Physiological Factors

In cold weather, exposure to cold wind can irritate the ocular surface, increasing eye secretions and causing contraction and spasm of the lacrimal canaliculi. This narrows the tear ducts, preventing tears from fully draining through the nasolacrimal system. This is a normal physiological phenomenon and usually improves with adequate rest.

2. Trauma

If there is ocular trauma, such as a ruptured lacrimal canaliculus, it may lead to nasolacrimal duct obstruction or narrowing. It is recommended that patients apply ice packs or cold compresses with a towel to the injured eye to help reduce swelling and pain.

3. Lacrimal Tract Infection

Infections of the lacrimal tract are common causes of the aforementioned conditions, including bacterial or viral infections. Patients are advised to follow medical guidance and use medications such as cefaclor capsules or cephalothin sodium for treatment.

4. Dacryoadenitis

Long-term wearing of contact lenses or excessive use of eye drops may lead to dacryoadenitis, which can cause lacrimal duct narrowing or obstruction. Patients may follow medical advice to take medications such as azithromycin capsules or clindamycin hydrochloride capsules.

5. Canaliculitis

Certain allergens, such as pollen or dust, may trigger canaliculitis, leading to lacrimal duct obstruction. Patients may follow medical instructions to use medications such as compound paracetamol and phenyltoloxamine tablets or amantadine-clemastine capsules.

If discomfort occurs, seek timely medical attention for targeted treatment to avoid delaying the condition.
