Optic neuropathy associated with GVHD after bone marrow allogeneic hematopoietic stem cell transplantation for B-Acute lymphoblastic leukemia: case report

Abstract

Abstract Background Graft-versus-host disease (GVHD) is the most common complication after bone marrow allogeneic hematopoietic stem cell transplantation (allo-HSCT). The incidence of posterior segment complications was significantly lower than that of ocular surface lesions. Up to now, there has been no report about optic neuropathy associated with GVHD. Case presentation A 23-year-old man presented with visual acuity decline after allo-HSCT for B-acute lymphoblastic leukemia (B-ALL). Red rashes were found all over the body simultaneously. Visual field examination revealed central scotomas in both eyes. Visual evoked potential showed prolonged P100 latency and decreased P100 amplitude in both eyes. Other ocular examinations showed no obvious abnormality except for blunt pupillary light reflex. The minimal residual disease test was negative after transplantation, and no obvious abnormalities were found in optic nerve and brain by magnetic resonance imaging (MRI). After the multi-disciplinary consultation, the rashes and optic neuropathy were considered GVHD probably. As for the treatment, methylprednisolone and Ruxolitinib were suggested, supported by adjunctive neurotrophic therapy. Two months later, the rashes gradually subsided. However, the visual acuity was not significantly improved at latest follow-up. Conclusions The present case report demonstrated GVHD probably associated with optic neuropathy. Although extremely rare, optic nerve should be considered as a potential target of ocular GVHD, which could expand the dimensions of GVHD.
