Randomized Controlled TrialThe effect of different doses of ketamine on intraocular pressure in anesthetized children.
When used for induction of anesthesia, ketamine usually increases intraocular pressure (IOP). However, the effect of low doses of ketamine, which are used for parental separation in children, is unknown. We studied the effect of two different doses of ketamine on IOP in anesthetized children. ⋯ In children anesthetized with halothane, ketamine had a dose-dependent effect on IOP, with 6 mg/kg of the drug causing a small increase in IOP at 5 to 10 minutes and 3 mg/kg not altering the IOP. The higher dose of ketamine also was associated with an increased incidence of postoperative complications.

Lack of efficacy of dilated screening for retinoblastoma.
To assess red reflex testing of the pharmacologically dilated pupil in screening for retinoblastoma. ⋯ Red reflex testing of the dilated pupil is a poor screening technique for retinoblastoma.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of mydriatic regimens used in screening for retinopathy of prematurity in preterm infants with dark irides.
To determine the mydriatic regimen that provides optimal dilation of the pupil with minimal systemic side effects for screening of retinopathy of prematurity. ⋯ The prepared combination of cyclopentolate 0.2% + phenylephrine 1% appears to be the mydriatic of choice for preterm infants with dark irides as it provided adequate pupillary dilation with the least systemic side effects.

Case ReportsCongenital horner syndrome and hemiplegia secondary to carotid dissection.
A 5-month-old infant had right Horner syndrome and left hemiplegia. Magnetic resonance imaging confirmed smaller cerebral hemisphere and magnetic resonance angiography showed reduced blood flow in the internal carotid artery on the right. A diagnosis of congenital hemiplegia and carotid occlusion secondary to maternal trauma during pregnancy was made.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of ondansetron with ondansetron plus dexamethasone for antiemetic prophylaxis in children undergoing strabismus surgery.
Children undergoing strabismus surgery have a high incidence of postoperative nausea and vomiting. Ondansetron plus dexamethasone is effective in reducing its incidence in many surgical procedures. ⋯ Ondansetron and ondansetron plus dexamethasone were equally effective in preventing early nausea and vomiting in children following strabismus surgery. However, the efficacy of dexamethasone in late postoperative nausea and vomiting could not be demonstrated. Further studies with a large population and different doses of dexamethasone may be warranted.
