purpose: to determine the prevalence and risk factors for retinopathy of prematurity (rop) in high risk premature infants admitted to nicu wards in isfahan from 2003 to 2008. methods: in this retrospective case series, 604 records of high risk infants were reviewed in terms of gestational age, birth weight, oxygen supplementation, delivery method, history of consanguineous marriage, single or m...

purpose: to determine the incidence of retinopathy of prematurity (rop) and to evaluate the possible neonatal risk factors for rop among premature infants referred to farabi eye hospital during 2000-2002. methods: newborn infants with gestational age (ga) £ 37 wk or birth weight (bw) £ 2500 g were included. the first eye examination was performed 4-9 weeks after birth. data on possible risk fac...

Skewed and multimodal lead-time demand (LTD) distributions can be present in supply chains. Under these conditions, logistics managers find that conventional approaches, which assume standard LTD distribution shapes, yield unreliable estimates of a single item’s reorder point (ROP) relation to meeting fill-rate targets under continuous review inventory policy. Furthermore, have limited data ava...

Objective: This study aimed to explore the influence of premature birth and mild retinopathy of prematurity (ROP) on the refractive status and the development of ocular optical components. Methods: The preterm infants who received fundus screening were divided into ROP group and non-ROP group. In addition, age matched term infants were also recruited. Results: The incidence of myopia was the hi...

Retinopathy of prematurity (ROP), the most common cause childhood blindness, is a hypoxia-induced eye disease characterized by retinal neovascularization. In normal retina, well-organized vascular network provides oxygen and nutrients as energy sources to maintain visual function; however, it disrupted when pathological angiogenesis induced in ROP patients. Under hypoxia, inadequate supply lead...

Growth pattern and nutritional intake as predictors of retinopathy of prematurity Background Retinopathy of prematurity (ROP) is a sight-threatening disease that affects extremely preterm and very preterm infants. Approximately 5–10% of infants screened for ROP go on to develop severe ROP that requires treatment. To minimize unnecessary screening procedures, which can be stressful for these fra...

To investigate the incidence and risk factors of retinopathy of prematurity (ROP) and Type 1 ROP in extremely preterm Chinese infants. A retrospective review of medical records was performed of all extremely preterm neonates (gestational age, GA≤28 weeks) screened for ROP from 2007 to 2012 at an ophthalmology centre in Hong Kong. Thirty-three maternal and neonatal covariates were analyzed using...

Improvement in neonatal care has led to increased survival rates of very premature infants. Accordingly, there are now more extremely preterm infants who are at risk of developing retinopathy of prematurity (ROP). ROP is a disorder of low birth-weight preterm infants and may lead to blindness. However, the prevalence of ROP varies globally, depending on different neonatal and ophthalmic care. T...

OBJECTIVE Insulin-like growth factor I (IGF-I) is necessary for normal development of retinal blood vessels in mice and humans. Because retinopathy of prematurity (ROP) is initiated by abnormal postnatal retinal development, we hypothesized that prolonged low IGF-I in premature infants might be a risk factor for ROP. DESIGN We conducted a prospective, longitudinal study measuring serum IGF-I ...
