The eye can become involved in immune-mediated diseases that affect it alone or as part of a multi-organ disease process. Much immunological attention has been focused on other organs affected by these processes and the subject of the immunology of eye diseases is a relatively new one. Many of these diseases that involve the eye are not life-threatening but can result in devastat- ing loss of sight that if bilateral, will have major effects on the patient's life. Systemic immunological investigations are generally unhelpful in these patients and one of the major problems in this field has...

The fact that certain adrenal steroid hormones are immunosuppressive and anti-inflammatory has been known for many years, and is routinely exploited by physicians. These effects are attributable to glucocorticoid steroids such as cortisol. Pharmacological doses of glucocorticoids inhibit most or all T cell types. However we now know that the effect of exposure to raised physiological levels is mainly to drive developing lymphocyte responses towards a Th2 cytokine profile (interleukin-4 secreting) while suppressing the development ofThi (gamma interferon secreting) lymphocytes. Only recently...
