Introduction
In most cases, white discharge from the corners of the eyes may be caused by natural aging, tear evaporation, dry eye syndrome, conjunctivitis, or trachoma. It is recommended to seek timely medical attention to determine the underlying cause and receive appropriate treatment. In daily life, maintain good eye hygiene by regularly cleaning the eye corners with warm water, keeping the eyes clean, and preventing infections.

Under normal circumstances, white discharge from the corners of the eyes may be caused by natural aging, tear evaporation, dry eye syndrome, conjunctivitis, or trachoma. It is recommended to seek timely medical attention to determine the underlying cause and receive targeted treatment. Specific analyses are as follows:

1. Natural Aging

With increasing age, the skin and glandular functions around the eye corners decline, leading to increased eye discharge. Daily use of moisturizing eye creams—such as hyaluronic acid-based eye care products—can help maintain skin elasticity.

2. Tear Evaporation

In dry environments, tears evaporate more quickly, causing salts and proteins in the tears to accumulate and form white discharge at the eye corners. It is important to maintain proper indoor humidity, take regular breaks for the eyes, and reduce prolonged use of electronic devices.

3. Dry Eye Syndrome

Dry eye syndrome may result from insufficient tear production, leading to decreased tear film stability. This often causes white discharge in the eye corners, possibly accompanied by symptoms such as dryness and eye fatigue. Treatment may include sodium hyaluronate eye drops, hydroxypropyl guar eye drops, or polyvinyl alcohol eye drops, as prescribed by a doctor.

4. Conjunctivitis

Conjunctivitis can be caused by bacterial or viral infections, or allergies. Inflammation leads to eye redness and increased white discharge, often accompanied by symptoms such as swelling and itching. Treatment under medical guidance may include emedastine difumarate eye drops, levofloxacin eye drops, or acyclovir eye drops.

5. Trachoma

Trachoma is caused by infection with *Chlamydia trachomatis*, which increases vascular permeability and stimulates excessive cellular secretion, resulting in white discharge. Symptoms may include eye pain. Treatment, as advised by a physician, may involve rifampicin eye drops, sulfacetamide sodium eye drops, or tetracycline eye ointment.

In daily life, maintaining good eye hygiene—such as regularly cleaning the eye corners with warm water and keeping the eyes clean—can help prevent infections.
