Blocked Tear What Are

Blocked Tear

A blocked tear, medically termed as epiphora, occurs when tears are unable to drain properly from the eyes. This can cause excessive tearing, eye irritation, and discomfort. Common causes of blocked tear ducts include:

1. Narrowing or obstruction of tear ducts: The tear ducts can become narrowed or blocked due to various factors, such as aging, inflammation, injury, or tumors. This can hinder the proper flow of tears.

2. Eyelid abnormalities: Certain eyelid abnormalities, such as ectropion (outward turning of the eyelid) or entropion (inward turning of the eyelid), can disrupt the proper drainage of tears.

3. Conjunctivitis (pink eye): Inflammation of the conjunctiva, the thin membrane that lines the eyelids and covers the white part of the eye, can cause swelling and irritation that may obstruct the tear ducts.

4. Stye (hordeolum): A stye is a small, red, and swollen bump on the eyelid that can press on the tear ducts and block them.

5. Allergies: Allergic reactions can lead to eye irritation, swelling, and increased tear production, which may overwhelm the tear drainage system.

6. Facial trauma: Injuries to the face, such as fractures, may damage the tear ducts or the bones around them, affecting tear drainage.

7. Medical conditions: Certain medical conditions, such as thyroid disorders, certain autoimmune diseases, and infections like dacryocystitis (infection of the tear sac), can cause blocked tear ducts.

It's important to seek medical attention if you experience persistent blocked tears, as early evaluation and management can help prevent complications and ensure proper eye function. Treatment for blocked tear ducts may involve medications, eyelid massages, or surgical interventions, depending on the underlying cause.
