Which of the following is a term for inflammation of the eyelash follicles?
Keratitis
Blepharitis
Cholesteatoma
Labyrinthitis
The correct answer and explanation is:
The correct answer is Blepharitis.
Blepharitis refers to the inflammation of the eyelash follicles, which are located at the base of the eyelashes. This condition can occur due to various factors, such as bacterial infections, seborrheic dermatitis (a skin condition), or an overgrowth of normal bacteria on the skin of the eyelid. In some cases, it is associated with rosacea or allergic reactions.
The primary symptoms of blepharitis include redness and swelling around the eyelash follicles, itching, burning sensations, and the sensation of something in the eye. It may also lead to crusting around the eyelashes, which can be more noticeable upon waking. In some cases, the eyelashes may even fall out or become misdirected, potentially causing irritation to the eye.
There are two main types of blepharitis:
- Anterior blepharitis: This involves the front part of the eyelid, where the eyelashes are located. It is often caused by bacteria or dandruff of the scalp and eyebrows.
- Posterior blepharitis: This affects the inner part of the eyelid and is usually linked to the malfunction of the meibomian glands, which produce oil for the eyes. This type of blepharitis can be associated with rosacea or other skin conditions.
Treatment typically involves good eyelid hygiene, such as warm compresses, gentle cleaning of the eyelid with a mild soap or baby shampoo, and in some cases, antibiotic or steroid eye drops. For chronic blepharitis, long-term care may be necessary to prevent flare-ups and manage symptoms.
Other terms:
- Keratitis is inflammation of the cornea, the clear, dome-shaped surface that covers the front of the eye.
- Cholesteatoma is an abnormal skin growth in the middle ear behind the eardrum.
- Labyrinthitis refers to inflammation of the inner ear, which can affect balance and hearing.
Blepharitis is a relatively common condition that can affect people of all ages, and early intervention is key to managing it effectively.
