The oculocardiac reflex in strabismus surgery.
During strabismus surgery on 81 extraocular muscles in 49 children the cardiac response to calibrated traction on each of the muscles operated on was studied through the use of a microdisplacement transducer and the tachometer of a cardiac monitor. There was no significant difference in the frequency of induction of the oculocardiac reflex between the medial rectus and the other muscles or betw...
متن کاملOculocardiac reflex associated with a large orbital floor fracture.
A 40-year-old man presented with bradycardia, left eye pain, and intermittent nausea 1 day after blunt trauma to the left orbit. Imaging revealed a large orbital floor fracture with significant herniation of orbital contents but no obvious extraocualar muscle entrapment. Oculocardiac reflex was suspected, and the fracture was repaired surgically within 24 hours of presentation. His bradycardia ...
متن کاملExperimental study of oculocardiac reflex (OCR) with graded stimuli.
The present study was conducted to observe the effect of graded mechanical stimuli on occurrence of oculocardiac reflex (OCR). The experiments were carried out in twenty albino rabbits of either sex weighing between 1-2 kg. Changes in heart rate and/or cardiac rhythm (oculocardiac reflex) were studied by applying traction with progressively increasing weights to medial rectus muscle. Mean thres...
متن کاملMinor head injury: pathophysiological or iatrogenic sequelae?
This study addresses the possibility that cognitive sequelae--albeit of a transient or minor character--can be associated with mild head injury. Twenty men (aged 16-30 years of age), whose post-traumatic amnesia did not exceed eight hours, were examined within 48 hours of their accident and again one month later. This unselected sample had no previous history of head injury. A control group of ...
متن کاملEye hue and the oculocardiac reflex.
During operations for squint nodal rhythm and other more serious arrhythmias such as heart block and multifocal ventricular extrasystoles, as well as the oculocardiac reflex, are shown to occur more frequently in patients with brown or hazel eyes than in patients with blue or grey eyes.
