“…P reterm infants are at higher risk for visual and other neurodevelopmental problems compared with infants born full-term (1)(2)(3)(4)(5)(6)(7). Those who are very low birth weight (VLBW Յ 1500) are at particularly high risk due to an increased prevalence of retinopathy of prematurity (ROP) (2,5,6,8,9), intraventricular hemorrhage (IVH), and periventricular leukomalacia (PVL), among other complications (6,7,10 -14).…”

“…One area of the brain that is particularly vulnerable during the prenatal and neonatal period is the primary visual pathway (from the retina to the visual cortex) because it undergoes significant development during this time (15)(16)(17)(18)(19) and therefore may be vulnerable to disruption by perinatal events. Several studies have shown an increased incidence of visual impairment with ROP (1,3,20,21) and with periventricular leukomalacia or hemorrhagic lesions (10 -13). A number of studies have also demonstrated the co-existence of visual impairment in preterm infants with other neurologic deficits (4,6,14).…”

Visual Development in Very Low Birth Weight Infants

ABSTRACT:Extremely preterm infants are at risk for neurodevelopmental problems and the visual system is particularly vulnerable. However, development of visual function in preterm infants with little or no retinal or neurologic injury has not been well defined. This study compared development of visual function in preterm infants without severe retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL) to that of term infants at 5-7 mo corrected age. Twenty-one very low birth weight (VLBW) preterm infants (24 -32 wk gestational age, weighing Ͻ 1500 g), and 22 healthy term infants were tested at 5-7 mo corrected age. Infants with any IVH/PVL and Ͼ Stage II ROP or Plus disease were excluded. Contrast sensitivity, grating acuity, and vernier acuity were measured using swept-parameter visual evoked potentials. Thresholds and maximum amplitudes were compared between groups. VLBW and term infants showed no differences in sensitivity for contrast (67.5 versus 63.8), grating resolution (12.4 versus 12.5 cpd) or vernier acuity (1.2 versus 1.0 arcmin). However, the amplitudes for swept contrast (p Ͻ 0.03) and swept vernier offset (p Ͻ 0.04) stimuli were higher in VLBW infants. Visual thresholds in VLBW infants without serious retinal or neurologic abnormalities were not significantly different from those of term infants, suggesting that increased visual experience does not influence visual sensitivity. The higher amplitudes in VLBW infants, suggests that visual experience may affect responses to suprathreshold stimuli.
