Purpose: To describe the clinical manifestations of multifocal choroiditis presumed to be secondary to allogenic bone marrow transplantation after development of self-tolerance to chronic graft-versus-host disease (GVHD).
Methods: Case report. A 17-year-old male who received an allogenic bone marrow transplant (BMT) from his HLA-identical sister.
Results: One year after BMT, grade II chronic GVHD developed. Two years later, vision deteriorated to 20/50 R.E. and 20/400 L.E. Ophthalmoscopic examination showed multiple chorioretinal punched-out scars throughout the posterior pole and mid-periphery of both eyes. Fluorescein angiography showed four choroidal neovascular membranes (CNVMs) in the right eye that were surgically removed, and a subfoveal disciform scar in the left eye.
Conclusions: Multifocal choroiditis is a possible complication related to allogenic BMT. It should be included as a late cause of BMT-associated choroidopathy. Surgical removal of vision-threatening CNVMs is a reasonable approach.
