Pupillometer* for use during anasthesia

ANASTHESIA FOR SIMULTANEOUS BILATERAL NEPHRECTOMY LEONArm

BILATERAL SIMULTANEOUS NEPHRECTOMY is a important surgical procedure prior to renal transplant. Any anaesthetist may be asked to anaesthetize for this operation, as these procedures may be carried out in centres other than those where the renal transplant may be performed at a later date The anaesthetic problems in bilateral nephrectomy are not unlike those associated with renal transplantation...

Comparison of measurement of pupil sizes among the colvard pupillometer, procyon pupillometer, and NIDEK OPD-scan.

PURPOSE To compare pupil sizes measured with the Colvard pupillometer, Procyon pupillometer, and NIDEK OPD-Scan. METHODS Pupil diameter was measured in 90 consecutive eyes from 55 patients under mesopic and scotopic light conditions with all three instruments. RESULTS The mean scotopic pupil diameter was 6.3+/-0.98 mm with the Colvard pupillometer and 6.45+/-1.01 mm with the Procyon pupillo...

Development of a Smartphone-based Pupillometer

In ophthalmology, a pupillometer, a device to measure the diameter of the pupil of the eye, can provide information on the function of the autonomic nervous system. The current pupillometers on the market are either too large to be a handheld instrument, or relatively expensive. In this study, a pupillometer based on a smartphone was designed. Both white and infrared LEDs and a 3M pixel camera ...

Repeatability of the procyon p3000 pupillometer.

Pupil examination: validity and clinical utility of an automated pupillometer.

Pupillary size and reactivity have long been a critical component of the clinical assessment of patients with neurological disorders. The pupillary examination may provide critical information related to new or worsening intracranial pathology and facilitate prompt intervention to minimize further neuronal damage. With this in mind, intensive care nurses caring for neurologically impaired patie...
