Aim To evaluate the effectiveness of early visual training and environmental adaptation on function neurological development in infants with impairment. Method This was a pilot intervention clinical trial study. Thirty (mean age 5.9mo, SD 2.1mo, range 4–11mo; 16 males, 14 females) peripheral impairment (PVI, n =15) or cerebral (CVI, participated 6‐month programme. matched 6mo, 1.4mo, 4–9mo; 18 12 served as comparison group. Primary outcome measures were acuity, contrast sensitivity, qualitative ocular motor functions. Secondary outcomes scores Griffiths Mental Developmental Scales (GMDS). Results The treatment group showed significant improvement all primary ( p <0.01). improved only acuity sensitivity greater than fixation =0.033) smooth pursuit CVI subgroup PVI GMDS subscales hand–eye coordination =0.01) performance <0.01) increased group, while total score decreased, driven by language =0.039) =0.025) subscales.
