About Follicular Conjunctivitis
Overview: Follicles in Conjunctivitis
Causes and Risk Factors
Follicular conjunctivitis is most commonly caused by viral infections that inflame the conjunctiva - a thin, clear mucous membrane that covers the inner surface of your eyelids and the white part of your eyeball. The specific causes can include herpesviruses, varicella-zoster virus, Epstein-Barr virus, adenoviruses, and rubella virus. Bacteria, such as Haemophilus influenzae and Chlamydia trachomatis, may also cause follicular conjunctivitis. In some cases, topical medications applied directly to the eye can cause a toxic follicular conjunctivitis.
Providers may describe conjunctivitis as follicular or papillary based on how the conjunctiva looks during an eye exam. In papillary conjunctivitis, small flat-topped nodules (papillae) form; in follicular conjunctivitis, the inflammation results in tiny dome-shaped nodules (follicles).
As for the risk factors:
- Non-modifiable risk factors include increasing age and genetic predispositions such as a positive family history of follicular conjunctivitis or related eye infections.
- Modifiable risk factors are largely related to individual habits and lifestyle. Poor hygiene practices, such as not washing hands frequently or sharing towels, can increase the risk of transmission and infection.
It is important to note that these risk factors may vary depending on the specific cause of follicular conjunctivitis. If you have concerns about your risk factors or symptoms, it is recommended to speak with a healthcare professional for an accurate assessment and appropriate management.
Prevention and reducing spread:
To prevent spreading the infection, it is important to practice good hand hygiene and avoid sharing towels or washcloths. Avoid touching your eyes and wash your hands frequently to reduce spread.
Symptoms
The most common early symptoms of follicular conjunctivitis include:
- Redness or pinkness in the whites of the eye
- Mild irritation in the eye
- Itchiness or watery eyes
- Feeling like something is in the eye
- Gritty feeling in the eye
Other symptoms of follicular conjunctivitis may include:
- Swelling or puffiness of the eyelids
- Increased sensitivity to light (photophobia)
- Pain or burning sensation in the eye
- Discharge from the eyes, which may cause the eyelashes to stick together
- Blurry or hazy vision
It's important to note that symptoms can vary from person to person and not everyone will experience all these symptoms. If you suspect you have follicular conjunctivitis or if your symptoms worsen, it is recommended to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
What do follicles look like in conjunctivitis?
In follicular conjunctivitis, follicles may appear as small, raised bumps on the inner eyelid surface. An eye exam can help a clinician identify follicles and determine what’s causing them.
Diagnosis
To diagnose follicular conjunctivitis, doctors commonly perform the following examinations, tests, and procedures:
- Medical history: The doctor will ask questions about your medical history to understand your symptoms and any underlying conditions.
- Physical examination: The doctor will examine your eyes for signs of inflammation, such as redness, swelling, and discharge.
- Symptoms assessment: The doctor will ask about your symptoms, including any itching, burning sensation, or sensitivity to light.
- Eye examination: The doctor will use a specialized instrument called a slit lamp to examine the front surface of your eyes and check for the presence of follicles in conjunctivitis on the conjunctiva.
- Microbiological tests: In some cases, the doctor may recommend microbiological tests to confirm the cause of the infection, especially if symptoms are persistent or the cause is unclear. This involves collecting a sample of the eye discharge and sending it to a laboratory for analysis.
Additional examinations, tests, and procedures may include:
- Assessment of pre-auricular lymphadenopathy: The doctor will check for tender lymph nodes near the ear, which can indicate an infection.
- Evaluation of purulent discharge: The presence or absence of significant purulent discharge can provide insights into the severity of the condition.
It is important to consult with your healthcare professional for personalized advice regarding examinations, tests, and procedures for diagnosing follicular conjunctivitis.
Treatment and Symptom Relief
The goals of treatment for follicular conjunctivitis are to alleviate symptoms, promote healing, and prevent transmission of the infection. The recommended treatments and their mechanisms of action include:
- Over-the-counter (OTC) artificial tears: These lubricating eye drops can provide relief from dryness and irritation.
- Warm compresses: Placing a warm, damp washcloth over the closed eyes can help soothe discomfort and reduce inflammation.
- OTC pain relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil) may help alleviate pain and reduce inflammation.
- Antibiotics: If follicular conjunctivitis is caused by a bacterial infection, doctors may prescribe antibiotics to target the underlying infection and promote healing.
- Symptom relief for viral conjunctivitis: Since viral infections do not respond to antibiotics, treatment focuses on symptom relief. This may include using artificial tears, warm compresses, and practicing good hygiene to prevent further spread of the infection.
- Follicular conjunctivitis often improves on its own within a few weeks. For many viral cases, symptoms may resolve in about 3 weeks or less, though timelines can vary.
It's important to note that medication dosing may be affected by various factors, so it's essential to consult with a healthcare professional for personalized advice. Side effects can occur with medications, so it's crucial to discuss potential risks with your healthcare provider or refer to the medication information provided.
When to see a doctor:
See a healthcare provider if your eye symptoms last more than a few days, or if you have worsening pain, blurred vision, or increasing light sensitivity. For children with possible conjunctivitis, a clinician can help determine the cause and next steps, since symptoms and care considerations may differ by age.
