Filter by:The purpose of this study is to determine if there is a relationship between time spent out the targeted oxygen saturation range in preterm infants is associated with long-term outcomes such as Retinopathy of Prematurity.
Newborns infants equal or less than 1500 grams and/or equal and less than 32 weeks will have ophthalmologic examination for ROP at 6 weeks old. They will be randomized blindly to receive 2 ml of 12.5% dextrose in water (D12.5W) orally five minute before examination (intervention group) or nothing (control). NIPS scale will be applied two minutes before examination and two minutes after examination.
The primary objective of the proposed study is to show that inhaled equimolar mixture of oxygen and nitrous oxide (EMONO) will reduce pain associated with retinal exam in the preterm infant, as compared to the current standard treatment (oral sucrose and topical anaesthesia). The investigators also aim to show that EMONO can be used safely in preterm neonates undergoing retinal exam, and will not result in any increase in apnea, bradycardia, or desaturation in the 24 hours following the exam. Finally, the investigators aim to show that EMONO will keep the infant calm, and make retinal examination easier and less traumatic.
The purpose of this study is to asses the relative influence of genetic and environmental influence on the tortuosity of retinal arterioles in eyes of 218 healthy Danish twins aged 20-46 years. We expect to find a high heredity for the variation in tortuosity. This knowledge can contribute to the elucidation of the pathology in retinal diseases.
Vitamin A is important for the development of healthy eyes and lungs. Very low birth weight premature babies have low body stores of vitamin A and are prone to diseases of the eye and lungs. Previous work has shown that intramuscular (IM) vitamin A reduces the number of babies who require prolonged oxygen therapy, and may also reduce the number of babies affected by retinopathy of prematurity (ROP)). There is also some evidence that the conjunctiva shows signs of deficiency of vitamin A in premature infants, particularly those who develop ROP. Our own work here in Glasgow suggests that, compared to babies born at full term, premature babies' eyes are less sensitive to light and we believe that this may reflect shortage of vitamin A in the eye. This study will examine the effects upon the eye of giving extra intramuscular vitamin A to very low birth weight, premature infants. We will also measure blood levels of vitamin A and calculate liver stores of this nutrient.
This pilot study was a randomized, placebo-controlled, clinical trial to measure changes in blood and urine levels of inositol in premature infants at high risk for retinopathy of prematurity (ROP) following a single intravenous dose of inositol. Based on previous studies, the premise is that maintaining inositol concentrations similar to those occurring naturally in utero will reduce the rates of ROP and bronchopulmonary dysplasia in premature infants. The objective was to evaluate the single-dose pharmacokinetics and safety of different amounts of intravenous myo-inositol (provided by Ross Products Division, Abbott Laboratories) in very low birth weight neonates, in preparation for a future Phase III multi-center randomized controlled trial. This study enrolled 74 infants at high risk for retinopathy at 9 NICHD Neonatal Research Network sites, and randomly assigned them to receive either 60mg/kg of 5% inositol, 120 mg/kg of 5% inositol, 60 mg/kg of 5% glucose (the placebo), or 120 mg/kg of 5% glucose.
Premature infants stand a risk of danger to the layer of the eye that creates sight that, if untreated, can cause severe vision problems, leading to blindness in some cases. This research study will use ultrasound to examine the eye for retinal changes of prematurity.
This study compared the use of continuous positive airway pressure initiated at birth with the early administration of surfactant administered through a tube in the windpipe within 1 hour of birth for premature infants born at 24 to 27 weeks gestation. In addition, these infants within 2 hours of birth, had a special pulse oximeter placed to continuously monitor their oxygen saturation in two different target ranges (85-89% or 91-95%). This study helped determine whether or not these two management strategies affect chronic lung disease and survival of premature infants.
To evaluate the effect of ambient light reduction on the incidence of retinopathy of prematurity (ROP).
To determine the safety and efficacy of trans-scleral cryotherapy of the peripheral retina in certain low birth-weight infants with retinopathy of prematurity (ROP) for reducing blindness from ROP. To determine the long-term outcome for eyes that had severe ("threshold") ROP, both with and without cryotherapy.
