Leukemic infiltrate versus anterior uveitis.

Anterior segment leukemic infiltrate (ASLI) is rare; it is found in 0.5% to 2.5% of all leukemic relapses. Its clinical manifestations, at times, are similar to those of anterior uveitis (AU). We report the cases of three patients, all of whom had ASLI as their primary manifestation of relapse. We observed some major clinical differences between ASLI and AU that may help differentiate these two conditions without using anterior chamber paracentesis and/or iris biopsy. The development of resistance to leukemic therapy is the major factor in treatment failure.
