Description
Your retina is so delicate that your own immune system would instantly destroy it. To save your vision, the eye builds an impenetrable cellular wall to keep your blood out. The human immune system is a ruthless army of white blood cells designed to seek out and destroy foreign bodies and damaged tissue. But this aggressive defense mechanism is wildly dangerous to the incredibly delicate, non-regenerative cells of the human retina. If a normal inflammatory response occurred inside your eye, you would be instantly and permanently blinded by your own body.To survive its own immune system, the eye employs a phenomenal structural quarantine known as the Blood-Aqueous Barrier. This is a fortress of tightly woven epithelial and endothelial cells that physically blocks almost all bloodborne immune cells and large proteins from entering the inner chambers of the eye, creating a state of absolute "immune privilege."This medical reference details the microscopic architecture of this biological firewall. We explore the terrifying consequences of intraocular trauma, where a puncture wound breaches the barrier, causing the immune system to suddenly "discover" the eye for the first time and launch a devastating autoimmune attack.Explore the most heavily guarded vault in the human body. Discover the delicate anatomical barrier that prevents your own aggressive blood from destroying your vision.
