The conjunctiva is a thin, clear membrane that plays a crucial role in eye health.
Understanding the Conjunctiva
The conjunctiva serves as a protective layer for the eye. Let's explore its details:
Structure and Location
- The conjunctiva lines the inner surface of the eyelids.
- It also covers the white part of the eyeball, which is known as the sclera.
- It's a delicate tissue containing many tiny blood vessels.
Function
- It provides lubrication to the eye by secreting mucus and tears.
- It helps protect the eye from external elements like dust and bacteria.
The Role of Blood Vessels
The numerous tiny blood vessels within the conjunctiva are important:
- They provide nutrients to the eye tissue.
- They give the sclera its characteristic pink or red tint when they are irritated.
Conjunctivitis
Inflammation of the conjunctiva is called conjunctivitis, often referred to as "pink eye".
Symptoms
- Redness in the white of the eye
- Itching or burning sensations
- Increased tear production
- Discharge from the eye
Causes
Conjunctivitis can be caused by:
- Viral or bacterial infections
- Allergies
- Irritants such as smoke or dust
