Follicular conjunctivitis is a specific type of inflammation of the eyes' outer coverings, predominantly the lining of the inside of the eyelids (conjunctiva). This particular condition is signified by the formation of round follicles (small bumps) and inflammation of the conjunctiva, predominantly in the lower eyelid and often involving both eyes. This type of conjunctivitis is typically due to infections, irritants, or allergies, with varying degrees of severity and potential complications.

Follicular Conjunctivitis Symptoms and Causes

Patients with follicular conjunctivitis may experience a range of symptoms depending on the cause and severity of the infection. Common symptoms include redness, irritation or itching of the eyes, a gritty feeling in the eyes, unusual production of tears, and sometimes, a mucoid or purulent discharge. Upon examination, follicles, typically in the lower eyelids, are observed.
Several agents can cause follicular conjunctivitis, including bacteria, viruses, chlamydia, and toxins. Viral causes are the most common, notably the adenovirus, which can also cause symptoms of a cold or sore throat. Exposure to certain chemical irritants, like chlorine in swimming pools, can lead to toxic follicular conjunctivitis. Allergies too can trigger this condition, a variant known as allergic conjunctivitis.
Chlamydial conjunctivitis, though rare, presents a more substantial health risk. It is typically sexually acquired and may coexist with other sexually transmitted diseases. Left untreated, it may result in various complications like chronic eye disease and scarring of the conjunctiva and cornea. 

Follicular Conjunctivitis Treatment

The treatment of follicular conjunctivitis is entirely dependent on the cause, hence the importance of a proper diagnosis. As it can be caused by an array of elements, from viruses to irritants and allergies, identifying the accurate cause aids in defining the most effective treatment regime. 
  1. In viral conjunctivitis, following a similar course to the common cold, caused by the adenovirus, there is currently no definitive antiviral treatment. Patients are thus advised to manage the symptoms through the usage of artificial tear drops to alleviate irritation, cold compresses to reduce inflammation, and strict hygiene practices to prevent spread, while the body fights off the virus.
  2. For bacterial causes, topical antibiotics are typically recommended. It is crucial that the type of bacteria is identified, as different ones can cause different forms of bacterial conjunctivitis, each responding better to specific antibiotics. 
  3. When chemical irritants are associated with the condition, immediate and thorough rinsing of the eyes is advisable to reduce the risk of any lasting damage. In cases of allergic conjunctivitis, the treatment comes in the form of antihistamine eye drops or pills, along with practices seeking to avoid exposure to the allergen.
  4. Chlamydial conjunctivitis requires systemic treatment with antibiotics to prevent complications, given the systemic nature of chlamydia. Any sexual partners of the patient also require treatment to prevent re-infection.
In conclusion, the treatment of follicular conjunctivitis begins with an accurate diagnosis, after which the necessary symptom management or specific conditioner treatments can be implemented successfully. Adequate follow-up after treatment is highly critical, particularly if there's no improvement or a worsening of symptoms.
