Abstract

Abstract: Aim: The aim of this study was to study long‐term visual outcome and cataract development in children and adolescents after hematopoietic stem cell transplantation (HSCT) in childhood. Methods: Best corrected visual acuity (BCVA), refraction and lens status were examined in a prospective study of 139 children and adolescents. Results: In total, 139 patients (58 female), median age 6.6 years at HSCT (range 0.4–17.5 years), were followed up for a median of 8.0 years (1–19.4 years). Median BCVA in the better eye was 1.0 decimal. Altogether 19 of 131 patients developed cataract requiring surgery, while 46 developed less prominent lens opacities and 66 had clear lenses at time of latest follow‐up. Patients conditioned with total body irradiation had a higher risk of developing lens opacities or cataract (p < 0.0001) as did patients with malignant disease, irrespective of irradiation treatment (p < 0.0001). Cumulative analysis showed that 50% of all patients had developed lens opacities/cataract after 10.2 years. Patients who ultimately needed cataract surgery developed cataract earlier than others (p = 0.006). Conclusion: Lens opacities or cataract were more common in children or adolescents with malignant disease and after conditioning with irradiation. Regular ophthalmological follow‐up is important after HSCT for early intervention to avoid amblyopia.
