To report a case of steroid-induced glaucoma in a child who was treated with systemic steroids for a long period due to graft-versus-host disease.

A 10-year-old male was referred to our ophthalmologic clinic for examination of papilledema due to persistent headache and nausea. He was diagnosed as aplastic anemia 8 years prior and took approximately 4,000 mg of oral prednisolone for 8 years from April 2007 to April 2015 for treatment of lung graft-versus-host disease after hematopoietic stem cell transplantation. His best corrected visual acuity was 0.8 (decimal) in the right eye, 0.5 in the left eye and intraocular pressure (IOP) measured using a Goldmann applanation tonometer was 42 mm Hg in the right eye and 43 mm Hg in the left eye. His cup-to-disc ratio was 0.8 in the right eye and 0.7 in the left eye. Additionally, superior and inferior neuroretinal rim thinning was present in both eyes. Despite using IOP-lowering agents, IOP was not controlled. However, after trabeculectomy with mitomycin C in both eyes, IOP became normalized.

In cases of pediatric patients treated with systemic steroids for a long period of time, regular observation is necessary to prevent IOP elevation and steroid-induced glaucoma.
