[Leukemic infiltration in the anterior chamber of the eye]

Leukaemic infiltration of the anterior chamber of the eye (hypopyon and corneal opacity) was the only sign of relapse in two girls with acute lymphoblastic leukaemia who had been off treatment for one and three years. The malignant cells had probably been present in the eye since the onset of the disease. The anterior segment of the eye may be a pharmacologycal "sanctuary" in patients with ALL. The response to radiotherapy was good but this treatment should be coupled with systemic chemotherapy and CNS prophylaxis.
