Glaucoma might be caused by T cells attacking the retina's heat shock proteins
Glaucoma may be an autoimmune disease - health science news

Surprising new scientific findings suggest that glaucoma, which is characterized by retina damage and can lead to blindness, is an autoimmune disease. Experiments in mice showed that retina cells are destroyed by the body’s own T cells. These particular immune cells target heat shock proteins that protect us against stress and injury, and are probably activated by heat shock proteins from bacteria that resemble the ones found in mice. Indeed, human glaucoma patients show high levels of T cells in the eye, whereas they are completely absent in the eyes of healthy people. The study therefore suggests that it could be possible to develop new treatment strategies to replace the inefficient current treatment of lowering the pressure in the eye.
