Immune Responses in Eye Infections

When the eye is infected, the immune system activates to defend against the invading microbes. This response includes the release of immune cells and proteins that target and eliminate the infection. Symptoms like redness, tearing, and swelling occur as blood flow increases and immune cells move to the site to fight off the pathogens. Additionally, the eye has unique mechanisms to protect its delicate structure, like limited inflammation to prevent damage to vision. Efficient immune responses are crucial, but sometimes can cause complications if the inflammation becomes excessive or leads to scarring.
