The aim of the study was to study visual acuity, visual perceptual, and VMI skills in patients after HSCT in childhood. Tests of visual perceptual skills, VMI, and visual acuity were performed in 102 children/adolescents (age range 4.3‐20.9 years). Mean time from HSCT to testing was 6.0 years (0.9‐17.5 years). Visual acuity was median 1.0 decimal (range 0.16‐1.6). Visual perceptual skills (memory, form constancy, visual sequential memory) and VMI were low compared to age‐equivalent normative data with, respectively, 36%, 45%, 60%, and 46% of all patients performing below the 25 percentile. All patients performed significantly lower than the 50 percentile in the reference material in visual sequential memory, P
