AIM: To assess motor functioning in children aged 4 years 6 months enrolled in
the Infant Aphakia Treatment Study, and to determine contributions of visual
acuity and stereopsis to measured motor skills. METHOD: One hundred and four
children (53% female) with unilateral aphakia randomized to intraocular lens or
contact lens treatment were evaluated at 4 years 6 months (age range 4y 6mo-4y
11mo) for monocular recognition visual acuity, motor skills, and stereopsis by a
traveling examiner masked to treatment condition. Motor skills were assessed with
the Movement Assessment Battery for Children - Second Edition (MABC-2). Visual
acuity was operationalized as log10 of the minimum angle of resolution (logMAR)
value for treated eye, best logMAR value for either eye, and intraocular logMAR
difference. RESULTS: Student's t-tests showed no significant differences in
MABC-2 scores between the intraocular lens and contact lens groups. The mean
total score was low (6.43; 18th centile) compared with the normative reference
group. Motor functioning was not related to visual acuity in the treated eye or
to intraocular logMAR difference, but was predicted in a regression model by the
better visual acuity of either eye (usually the fellow eye), even after
accounting for the influence of age at surgery, examiner, orthotropic ocular
alignment, and stereopsis. INTERPRETATION: Children with unilateral congenital
cataract may have delayed motor functioning at 4 years 6 months, which may
adversely affect their social and academic functioning.
