  • Title: Irradiation cataract in children after bone marrow transplantation.
    Author: Lappi M, Rajantie J, Uusitalo RJ.
    Journal: Graefes Arch Clin Exp Ophthalmol; 1990; 228(3):218-21. PubMed ID: 2193848.
    Abstract:
    Chemotherapy and radiation produce a dose-dependent anti-leukemic effect. Combined chemoradiotherapy and bone marrow transplantation (BMT) were given in our clinic to treat children with acute leukemias. Total body irradiation of 10 Gy in a single dose was used. One long-term side effect of this treatment was the development of subcapsular cataract; this was seen in all nine long-term survivors of the 17 children with acute lymphoblastic (ALL) or acute myelogenous (AML) leukemia who were treated as described above. One year after marrow transplantation, all the eyes studied had visual acuity of 20/20 and an optically clear lens. Three years later, 60% of the eyes had visual acuity of less than 20/40 and all had posterior, subcapsular cataracts. The cataract in all cases was quite uniform, consisting of opacities in the posterior subcapsular region. Cataract formation was treatment-related and seemed to correlate only to the type of total body irradiation. We concluded that the cataracts seen in the present study were a late complication of allogeneic BMT and were specifically due to the single-dose total body irradiation.
