Mother-infant interactions with infants with congenital visual impairment and associations with longitudinal outcomes in cognition and language.

Background: This study investigated mother-infant interactions, including maternal maintaining of infant attentional focus and sensitivity, with infants with congenital severe and profound visual impairment (VI) and the association with developmental trajectories from one to three years.

Method: Fifty-five infants and mothers were video-recorded playing together with a standard set of toys at Time 1 (T1) mean age 12.95 months (8.

Home-based early intervention in infants and young children with visual impairment using the Developmental Journal: longitudinal cohort study.

Aim: To investigate the effects of home-based early intervention in children with severe visual impairment (SVI) using the Developmental Journal for babies and young children with visual impairment (DJVI).

Method: A longitudinal observational study was undertaken with a national cohort (OPTIMUM) of infants with congenital disorders of the peripheral visual system (CDPVS) and profound-SVI; and followed up after 12 months and 24 months. Intervention was categorized according to the practitioner diary records of their usual practice over 12 months from baseline comparing those receiving the DJVI and those receiving 'Other Support'.

Functional vision and cognition in infants with congenital disorders of the peripheral visual system.

Aim: To investigate how vision relates to early development by studying vision and cognition in a national cohort of 1-year-old infants with congenital disorders of the peripheral visual system and visual impairment.

Method: This was a cross-sectional observational investigation of a nationally recruited cohort of infants with 'simple' and 'complex' congenital disorders of the peripheral visual system. Entry age was 8 to 16 months.
