BACKGROUND In children, sevoflurane is the most commonly used anaesthetic. Its excellent haemodynamic tolerance gives it a wide therapeutic index. This halogenated agent can abolish movement [minimal alveolar concentration (MAC)] or haemodynamic responses (MACBAR) to noxious stimulus in children as in adults. Reflex pupillary dilatation (RPD) has been demonstrated as a very sensitive measure of...

Objective: To evaluate the effect of adding topical Nepafenac 0.1% eye drop on increasing mydriasis in patients with Diabetes Mellitus type 2. Methods: study was conducted 73 eyes who had 2 diabetes for 5 years or more. The pupil diameter (PD) measured both without dilation using an Autorefractokeratometer (Grand Seiko\GR- 3500 Ka), then pupils were dilated Tropicamide 1%. A second measurement ...

RATIONALE Although transscleral-fixated intraocular lens (IOL) implantation has been the most frequently chosen treatment for patients with inadequate capsule support, the ghost pupillary capture phenomenon did not cause enough attention. PATIENT CONCERNS We present an unusual case withintermittent pupillary capture of intraocular lens. DIAGNOSIS After 5 minutes staying in the dark environm...

Introduction Pupillometric measures of cognitive and emotional processes Changes in pupil diameter provide a unique window on brain activity. We would like to thank Dr John Andreassi, editor of the International Journal of Psychophysiology, for the opportunity to be guest editors of this special issue on pupillometric studies. This volume is an expansion of the symposium 'Pupillometry and Cogni...
