Eye immune system

The eye immune system, protects the human eye infections and regulates sicatrización after of a wound process. The interior of the eye lacks lymphatic vessels but highly vascularized, and many immune cells reside in the uvea, including macrophages, mast cells and dendritic cells. These cells in the eye immune system fight infections and intraocular inflammation that can manifest as a result of a uveitis, iritis, or retinitis.
The cornea of the eye is a tissue immunologically very special, because it is exposed continuously to the outside world. So it is vulnerable to a wide range of microorganisms at the time that moist mucosal surface make it particularly susceptible to attack. Also lacks a vascular system that transport white blood cells. Therefore, that the immunological defence is a difficult task. However the immune response of the cornea is vascularizados surrounding, as the ciliary, processes as well as answer-cell immune to that reside within the cornea as the queratocitos, which are fibroblástos corneal tissue.Another component of the cornea eye immune system are the tears that cleans the surface when it is attacked by micro-particles.
