Which type of allergic conjunctivitis is more commonly associated with pollen exposure?

• A. Perennial
• B. Giant Papillary Conjunctivitis
• C. Seasonal
• D. Bacterial Conjunctivitis

Answer: (C)

Seasonal allergic conjunctivitis is driven by outdoor pollen exposure, which fluctuates with the seasons. When pollen counts rise, the conjunctiva becomes sensitized to these airborne allergens, triggering an IgE-mediated release of histamine and other mediators. This produces hallmark symptoms such as itching, redness, and tearing that peak during high-pollen periods. Perennial allergic conjunctivitis, by contrast, results from indoor allergens and occurs year-round rather than tied to a season. Giant papillary conjunctivitis is typically related to contact lens wear or ocular prostheses and presents with large papillae on the upper eyelid, not specifically linked to pollen. Bacterial conjunctivitis is infectious and presents with purulent discharge rather than allergic seasonality. So, the type most commonly associated with pollen exposure is the seasonal form.
