Follicular conjunctivitis is an eye surface condition marked by small, round lymphoid bumps on the inner eyelids. These bumps appear as pale, elevated follicles during an exam. Viral infections, allergic reactions, and some chronic irritants commonly trigger it. Redness, tearing, and discomfort are frequent symptoms. The pattern of follicles helps guide diagnosis.
read more about follicular conjunctivitis ...Viral infections, especially adenovirus, are the most frequent cause. Allergens can also stimulate follicle formation. Long-term exposure to irritants or certain medicines may contribute. The immune system reacts by producing clusters of lymphoid tissue. Identifying the trigger helps shape treatment.
Symptoms usually involve both eyes.
A slit lamp exam reveals follicles and checks for membrane formation. Doctors evaluate discharge type and lid swelling. History helps determine whether a virus, allergen, or irritant is likely. Severe cases may require lab testing to confirm viral subtype or rule out other causes.
Treatment depends on the trigger. Viral cases often improve with supportive care such as cold compresses and lubrication. Allergic cases respond to antihistamine or mast cell?stabilizing drops. Avoiding irritants helps when chronic exposure plays a role. Follow-up confirms recovery.
Viral cases spread easily, while allergic and irritant types do not.
Viral cases can last one to three weeks, depending on severity.
Mild cases do not, but severe membrane-forming infections can in rare situations.
Seek care if symptoms worsen, vision changes, or pain develops.
