Leucocyte-migration inhibition induced by uveoretinal antigen in patients with diabetic retinopathy.

Leucocyte-migration inhibition was to determine the state of hypersensitivity in 65 diabetic patients with different stages of retinopathy and 21 nondiabetic controls. About one third of the patients with simple or proliferative retinopathy exhibited significant leucocyte-migration inhibition of 0.2 mg/ml.

Leucocyte migration test in patients after corneal transplantation.

Twenty-four patients with corneal homografts were repeatedly evaluated by the leucocyte migration test using pooled human corneal extract 0.2 mg/ml as antigen. All patients were treated with small doses of local or systemic steroids.
