PURPOSE To evaluate the results of excimer laser photorefractive keratectomy (PRK) for myopia in pediatric eyes with amblyopia resulting from anisometropia. SETTING Clinica de Ojos Dr. Nano, Buenos Aires, Argentina. METHODS Five children with amblyopia resulting from anisometropia in whom conventional therapy was unsuccessful had PRK followed(More)
PURPOSE To describe our experience with noncontact holmium:YAG laser thermal keratoplasty (Ho:YAG LTK). SETTING Refractive Surgery and Cornea Department, Clinica de Ojos Dr. Nano, Buenos Aires, Argentina. METHODS In this retrospective study, 182 hyperopic eyes from 116 patients were treated with noncontact Ho:YAG LTK. Mean age was 50 years +/- 7 (SD),(More)
In anesthesized, paralyzed, and mechanically ventilated rabbits, the rate and duration of airflow were varied to investigate the effect on the central respiratory rhythm during 1:1 entrainment (1 phrenic nerve burst for 1 pump inflation). Our results showed that 1) the largest range of 1:1 entrainment was obtained with the longest inflation durations(More)
The aim of this study was to determine whether pulmonary receptors other than slowly adapting stretch receptors are capable of entraining the respiratory rhythm when periodically stimulated during artificial ventilation. Experiments were performed on anaesthetised (urethane, 1.5 g/kg) and paralysed (pancuronium bromide, 0.1 mg/kg) rabbits. Vagi were cooled(More)
The ability to detect small changes in tidal volume (VT) during either volitional or passive breathing was compared in seven normal subjects. Passive breathing was achieved with positive pressure applied at the mouth by a ventilator. Although baseline breathing pattern was similar for each subject during the two types of breathing, the ability of the(More)
