Immune Privilege: Do Your Eyes Have a 'Separate' Immune System?

The video explains how the immune system protects the body from pathogens, but the eyes and brain maintain a distance from it to avoid inflammation and damage. The eyes have immune privilege, a special status that limits immune response to protect vision. This includes the blood-eye barrier, lack of direct lymphatic drainage, and immunosuppressive molecules. Antibacterial substances like lysozyme in tears help protect the eyes from bacteria. However, immune privilege can be a downside if a strong immune response occurs, potentially causing damage to the eye.
