The maturation of visual acuity in neurologically normal and abnormal newborn infants.
The maturation of visual acuity was studied in 162 neurologically normal and 96 neurologically abnormal newborn infants. Ninety-five percent of the neurologically normal infants developed an acuity of 80 min arc by 35 weeks postmenstrual age (PMA) but only 50% developed an acuity of 40 min arc by 40 weeks PMA. Neurologically abnormal infants, and in particular those with periventricular haemorrhage (PVH), had a delay in the development of acuity. There was a close correlation between the development of 80 min arc acuity and the appearance of the first positivity of the flash visually evoked potential (VEP).
