Children with mucopolysaccharidosis risk progressive visual dysfunction despite haematopoietic stem cell transplants

• Aim: This prospective study assessed the long-term ocular and visual outcomes of children with mucopolysaccharidoses type I Hurler syndrome (MPS IH) who were treated with haematopoietic stem cell transplants (HSCT). Methods: Clinical ophthalmological assessments were performed on eight patients at the St Erik Eye Hospital, Huddinge, Stockholm, Sweden, from 2001-2018: The median age at diagnosis and HSCT were 12.2 (range 5.0-16.4) and 16.7 (8.0-20.4) months. The last eye examination was at a median of 13.4 (6.3-19.0) years and follow-up lasted a median of 12.0 (5.0-17.4) years. Results: Poor visual acuity, poor night vision and, or, photophobia were reported by six children. The best corrected visual acuity at the last visit was a median of 0.4 and 0.5 in the right and left eye and had declined significantly in two patients. Corneal opacities had increased despite HSCT in five patients. High hyperopia, at a median of +6 Dioptres, occurred in all patients and stiff corneas in all four patients that were measured. The patients' corrected intraocular pressures were normal. Retinal degeneration was identified in two patients. Conclusion: Despite HSCT, the long-term follow-up of patients with MPS IH showed reduced visual acuity due to corneal opacities or retinal degeneration.
