Retinal, visual, and refractive development in retinopathy of prematurity.

Eye Brain 2016 20;8:103-111. Epub 2016 May 20.

Department of Ophthalmology, Boston Children's Hospital and Harvard Medical School, Boston, MA, USA.

The pivotal role of the neurosensory retina in retinopathy of prematurity (ROP) disease processes has been amply demonstrated in rat models. We have hypothesized that analogous cellular processes are operative in human ROP and have evaluated these presumptions in a series on non-invasive investigations of the photoreceptor and post-receptor peripheral and central retina in infants and children. Key results are slowed kinetics of phototransduction and deficits in photoreceptor sensitivity that persist years after ROP has completely resolved based on clinical criteria. Read More

Allocentric Spatial Performance Higher in Early-Blind and Sighted Adults Than in Retinopathy-of-Prematurity Adults.

Perception 2016 Mar 1;45(3):281-99. Epub 2015 Oct 1.

Department of Psychology, University of Toronto at Scarborough, ON, Canada.

The question as to whether people totally blind since infancy process allocentric or external spatial information like the sighted has caused considerable debate within the literature. Due to the extreme rarity of the population, researchers have often included individuals with retinopathy of prematurity (RoP--over oxygenation at birth) within the sample. However, RoP is inextricably confounded with prematurity per se. Read More

Lack of association of genetic polymorphisms of angiotensin-converting enzyme gene I/D and glutathione-S-transferase enzyme T1 and M1 with retinopathy of prematures.

Genet Mol Res 2010 Oct 26;9(4):2131-9. Epub 2010 Oct 26.

Department of Ophthamology, Uludag University, Medical Faculty, Bursa, Turkey.

One of the most frequently observed causes of blindness in infancy is the pathogenesis known as retinopathy of prematurity (ROP). Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system; it is involved in the development of cardiovascular system diseases linked to I/D polymorphism of the ACE gene. Glutathione-S-transferase enzyme (GST) is one of the most important regulating components of the antioxidant system; there are indications that certain polymorphisms of GST genes (GSTT1, GSTM1), especially the null genotypes, increase the tendency for oxidative stress diseases.

Neonatal complications following preterm birth.

BJOG 2003 Apr;110 Suppl 20:8-16

Division of Neonatology, University of Utah, Utah, Salt Lake City 84132, USA.

Improvements in neonatal intensive care during the last 20 years have increased the survival of the most immature newborns at 23 weeks from 0% to 65% at some centres, although rates vary widely among neonatal care centres. University of Utah, USA data show that each week in utero after week 23 raises survival by 6-9%, to 90% by 27-28 weeks and 95% by 33 weeks. Provision of care in specialised centres to provide high-risk obstetric and neonatal intensive care, prenatal treatment with corticosteroids, postnatal treatment with surfactant and nitric oxide, and improvements in respirators and equipment to care for extremely immature infants all contribute to these changes.

[Perinatal events and handicaps].

Authors:
C Corchia

Pediatr Med Chir 1986 Jul-Aug;8(4):461-70

It is difficult to assess how large is the proportion of handicap in the pediatric age related to perinatal events; this is mainly due to the following reasons: lack of uniform criteria and accuracy in defining both "handicap" and the "perinatal period"; variable involvement of perinatal factors in the genesis of the different types of impairment; and multifactorial origin of most sensory, neural and developmental damages. For the same reasons it is no easy to assess if handicaps of perinatal origin are declining or increasing with time. Cerebral palsy (CP), retinopathy of prematurity (ROP), deafness and relational problems are probably the clinical conditions most strictly related to perinatal events, tough recently biological and familial prenatal factors have also been proposed as important antecedents of CP.
