“…There is no disputing the increased prevalence of strabismus among children born preterm, with reported rates varying between 10% and 22%. 36 , 37 , 38 Our results not only further attest to this observation but also show a higher rate (36%) of strabismus in the EP group, suggesting a positive association between the degree of prematurity and the prevalence of strabismus. By contrast, to our knowledge, there is a paucity of data with regard to strabismus type in infants born preterm.…”

Key Points Question What are the long-term ocular sequelae for young adults born extremely preterm (≤25 weeks’ gestation)? Findings In this cohort study conducted in the UK and Ireland with 19 years of follow-up comparing 128 former extremely preterm infants with 65 age-matched full-term controls, extreme prematurity was associated with an increased prevalence of visual and ocular deficits. These deficits varied with, but were not fully explained by, neonatal retinopathy of prematurity status. Meaning Extreme prematurity may have lifelong ocular implications that extend into adulthood; this study suggests that, for individuals born extremely preterm, ocular sequelae may be independent of the presence of neonatal retinopathy of prematurity and may be due to other causes.

“…Some of the differences may be attributable to classification by clinical characteristics, not aetiology. Given the higher rates of neurological deficits in children with ROP and that neurological deficits due to white matter injury are associated with a high incidence of strabismus,28 31 it is impossible to determine the direct impact of ROP alone. Strabismus per se can lead to loss of visual function from strabismic amblyopia and thus needs to be detected so that the child can be referred for treatment.…”

The preterm baby may develop ophthalmic sequelae which can be due to prematurity per se, due to retinopathy of prematurity (ROP) or due to neurological damage. Focusing on the former two, we discuss how in high-income countries the risk of sight-threatening ROP is largely confined to babies <1000 g birth weight (BW), whereas in low-income or middle-income countries babies exceeding 2500 g BW can be blinded. The effects of prematurity and ROP are presented as regional and global estimates of acute-phase ROP and the consequent mild/moderate and severe visual impairment. We discuss sequelae and how they affect the eye and its shape, strabismus and finally consider their impact on visual functions, including visual acuity, the visual field, colour vision and contrast sensitivity.

“…En la DTI, las áreas con menor FA exceden a las anomalías vistas con RM conven cional. Sin embargo, cuando se estudian las habilida des visuoespaciales teniendo en cuenta los proble mas de alineamiento de los ojos, más frecuente en estos pacientes, es este factor el que predice las defi ciencias visuoespaciales más que las anomalías de la sustancia blanca por inmadurez [85].…”

Introducción. Durante largo tiempo olvidada como contribuyente a la organización de las operaciones cognitivas, la sustancia blanca cerebral es, en la actualidad, objeto de estudio. Estos avances se complementan con las nuevas técnicas de neuroimagen, como el tensor de difusión, que permiten una visualización más detallada de cómo las vías de la sustancia blanca participan en las operaciones cognitivas. Desarrollo. Se revisa la relación de lesiones en la sustancia blanca con diferentes procesos y funciones cognitivas, como el lenguaje, atención, habilidades visuoespaciales y visuoconstructivas, negligencia espacial, velocidad de procesamiento, memoria y funciones ejecutivas. Conclusiones. El foco de atención sobre la sustancia blanca y sus trastornos promete ampliar el conocimiento del cerebro como un órgano extraordinariamente complejo en el que la conectividad y la velocidad de procesamiento proporcionada por la sustancia blanca son aspectos centrales para la cognición, la emoción y la propia consciencia. La sustancia blanca no parece ser el depósito de procesos y funciones cognitivas, sino que su papel se vincularía a dos propiedades necesarias para que un sistema de alta complejidad como el cerebro sea eficaz, como son la velocidad y la conectividad, procesos en los que debemos profundizar y, tal vez, comenzar a dilucidar su papel diferencial en el resultado de los procesos cognitivos. Palabras clave. Alteraciones cognitivas. Anisotropía fraccionada. Neuroimagen. Sustancia blanca. Tensor de difusión.
