Multiple Myeloma Relapse Presenting as Unilateral Blindness

Multiple Myeloma is a chronic disease. While therapy is largely focused for control, relapse is inevitable. Central nervous system relapse of myeloma is less common. Unilateral painless blindness is a rare entity and its occurrence in the setting of multiple myeloma has not been commonly reported. We encountered a case of multiple myeloma on treatment, who developed unilateral blindness and later on confirmed to have relapse of disease.
