Postoperative nausea and vomiting continues to be a common perioperative complication for pediatric strabismus patients. Postoperative pain management and the choice of general anesthetic can increase the incidence of perioperative nausea. Current techniques for induction of general anesthesia and selection of agents, prevention and treatment of postoperative pain, and options for antiemetic therapy will be reviewed.

The purpose of this study was to provide normative distance stereoacuity data for the Mentor B-VAT II-SG video acuity tester (Mentor O & O, Norwell, Mass.). ⋯ The B-VAT II-SG system produces reliable distance stereoacuity data. The norms we obtained may aid the clinician to detect binocular visual disturbances or may provide a basis for using distance stereoacuity as a screening method.

Hemangiomas of the orbit and eyelids may cause serious ocular problems usually related to amblyopia and astigmatism. Steroids have become the accepted treatment. However, some hemangiomas are resistant to steroids or require prolonged use,with unacceptable side effects. Interferon alfa-2b, an antiangiogenic protein, was used in this prospective study to treat visually threatening hemangiomas that were unresponsive to oral or intralesional steroid treatment. ⋯ Interferon alfa-2b treatment resulted in good to excellent regression of all the hemangiomas. This regression was clinically significant,with patients able to open the affected eye an average of 6 weeks into treatment. Visual results were good, with moderate amblyopia occurring only in patients treated at a later age. Interferon alfa-2b was well tolerated by these young patients, and no significant illness or side effect has occurred.

Extracorporeal membrane oxygenation (ECMO) is a form of cardiopulmonary bypass therapy used in term or near-term infants with severe cardiorespiratory disorders not responsive to conventional intensive care interventions. An ECMO-associated retinal vasculopathy has been described with little reference to the specific condition of the patient. We examined the eyes of 91 infants who underwent ECMO treatment. An assessment was made of the following: (1) when retinal changes occurred, (2) whether there was a particular systemic disorder or ECMO approach associated with these retinal findings, and (3) whether there may be ocular sequelae from this development. ⋯ Because we were able to examine infants while they were receiving ECMO or shortly after termination of bypass, asymmetric vasculopathy was found in a greater percentage of our patients compared with a similar large case series. ECMO-associated retinal vasculopathy appeared to disproportionately occur in those patients with CDH who underwent venoarterial bypass. Further study of retinal vascular changes in patients with CDH should be performed to assess long-term effects.
