Inflammation is a process by which an immune response is mounted, often translating into increased blood flow to the area (to bring more immune cells), swelling from edema, redness in appearance, heat and often pain. Inflammation is usually a sign that an infection or some other threat that causes the immune system to activate and react is present.
As a result, conjunctivitis often occurs when the conjunctiva, which does serve as a barrier to infectious agents, detects the presence of a pathogen and wishes to remove it. Keep in mind that this could be for a number of reasons: bacterial infections, viral infections, even allergies can cause conjunctivitis.
