Development of smooth pursuit eye movements in very preterm infants: 1. General aspects

چکیده
AIM To investigate early oculo-motor development in a population-based cohort of very preterm infants. METHODS Early oculo-motor development was prospectively studied by measuring smooth pursuit eye movements at 2 and 4 months corrected age in a population of very preterm infants born in Uppsala County 2004-2007. Eighty-one preterm infants were studied, and 32 healthy term infants constituted the control group. RESULTS The study group consisted of infants with a mean gestational age of 28 + 5 weeks. At 2 and 4 months corrected age, infants born very preterm showed lower gain (p < 0.001) and proportion of smooth pursuit eye movements (p < 0.001) compared to the control group. The boys showed higher gain of smooth pursuit eye movements at both 2 and 4 months corrected age, compared to girls. CONCLUSIONS Oculo-motor development measured by smooth pursuit eye movements is delayed in very preterm infants at 2 and 4 months corrected age. This might be a risk factor or early indicator of later perceptual and behavioural impairment.

متن کاملThe role of eye movements in depth from motion parallax during infancy.
Motion parallax is a motion-based, monocular depth cue that uses an object's relative motion and velocity as a cue to relative depth. In adults, and in monkeys, a smooth pursuit eye movement signal is used to disambiguate the depth-sign provided by these relative motion cues. The current study investigates infants' perception of depth from motion parallax and the development of two oculomotor f...

PURPOSE To investigate the development of smooth pursuit in infants and to assess the influence of different stimulus characteristics. METHODS A total of 131 eye movement recordings were obtained from 71 infants between 1 and 18 months of age using infrared photo-oculography. Smooth pursuit eye movements (SPEM) were stimulated using targets of different sizes (1.2° and 4.7° of visual angle) a...
متن کاملPoor repertoire General Movements predict some aspects of development outcome at 2 years in very preterm infants.
BACKGROUND Observation of the quality of endogenously generated "General Movements" has been proved to be a reliable and sensitive tool in the assessment of fragile neonates. The absence of fidgety movements at 2-4 months post-term is highly predictive of Cerebral Palsy. On the contrary, the presence of a poor repertoire pattern during the writhing period is not reliable in predicting motor or ...
متن کاملSmooth pursuit in 1- to 4-month-old human infants
The ability of human infants < or = 4 months of age to pursue objects smoothly with their eyes was assessed by presenting small target spots moving with hold-ramp-hold trajectories at ramp velocities of 4-32 deg/sec. Infants as young as 1 month old followed such target motions with a combination of smooth-pursuit and saccadic eye movements interrupted occasionally by periods when the eyes remai...
