Abstract:
A serous retinal detachment and choroidal hemorrhagic infiltration developed in a 17-year-old girl with acute lymphoblastic leukemia one year after cessation of therapy without concurrent bone marrow (BM) or central nervous system relapse. A choroidal biopsy through a sclerotomy with simultaneous release of subretinal fluid revealed no malignant cells. Accordingly, she was treated with prednisone, topical corticosteroid and atropine with normalisation of vision and clinical findings. Five months later the retinal detachment and choroidal infiltration recurred. In order to re-attach the retina once more and obtain a representative choroidal biopsy, a pars plana vitrectomy followed by a retinotomy with removal of subretinal tissue was done revealing leukemic infiltration of the choroid. Simultaneously a BM relapse was diagnosed.
