VLBW infants are at risk of lesions including intraventricular haemorrhage and periventricular leucomalacia. Those with normal IQ still present with reading difficulties. Oculomotor performance was assessed on 14 VLBWs (IQ > 85) and 15 full-term age-matched controls. Anti-saccade errors were significantly higher for the VLBWs (78%) compared to full terms (62%) (P = 0.02). Smooth pursuit latency was longer for the VLBWs compared to the full terms. Greater anti-saccade errors may be indicative of a lesion affecting the frontal cortex or developmental delay. Oculomotor deficits in VLBW children may be associated with the higher incidence of reading difficulties that have been reported.
