Ocular manifestations in adult T-cell leukemia/lymphoma.
Ocular manifestations of adult T-cell leukemia/lymphoma (ATL) are rare events. However, several ocular lesions which resulted from human T-cell leukemia virus type I (HTLV-I) infection have been reported, including direct infiltration of ATL cells, cytomegalovirus retinitis, and HTLV-I-associated uveitis (HAU). The aim of this study was to characterize ocular involvement in ATL and to correlate these lesions with HTLV-I proviral DNA integration. Three patients with acute-type ATL and ocular lesions were evaluated hematologically and ophthalmologically. Analysis of HTLV-I proviral DNA was carried out with a standard Southern blot technique using DNA from abnormal lymphocytes in peripheral blood. Two patients developed intraocular lesions located within intermediate and/or posterior segments which were caused by infiltration of ATL cells. Ocular lesions in one patient, which were localized to the anterior-intermediate segment, closely resembled those of HAU. Analysis of HTLV-I proviral DNA revealed multiple integrations in all three patients. The present study indicated heterogeneity in ocular manifestations of ATL. Multiple HTLV-I proviral DNA integrations may be associated with intraocular involvement in this disease.
