Pupillary diameter and reaction to light in preterm neonates.
The pupil controls the amount of light entering the eye. We have examined both the time course for the development of the light reflex and pupil diameter before and after this event in 50 neonates. The pupillary light reflex was absent in all neonates of less than 30 weeks' gestational age, it gradually developed from this age and by 35 weeks it was present in all. Several possible mechanisms t...

متن کاملPupillary Light Reaction during High Altitude Exposure
PURPOSE This study aimed to quantify the pupillary light reaction during high altitude exposure using the state of the art Compact Integrated Pupillograph (CIP) and to investigate a potential correlation of altered pupil reaction with severity of acute mountain sickness (AMS). This work is related to the Tübingen High Altitude Ophthalmology (THAO) study. METHODS Parameters of pupil dynamics (...
متن کاملIs there any difference in human pupillary reaction to acupuncture between light- and dark-adaptive conditions?
OBJECTIVES To determine if acupuncture stimulation elicits a pupillary response under light adaptation and whether there is any difference in the pupillary response between light and dark adaptation environments during acupuncture stimulation. METHODS The participants consisted of 55 healthy individuals who had no known eye diseases or pupil abnormalities. Experiment 1 compared pupillary resp...
متن کاملEffect of squint surgery on pupillary diameter.
AIM To investigate the effect that squint surgery has on pupillary diameter. METHODS The effect of squint surgery on pupil size was investigated in 19 patients. RESULTS A significant mydriasis in the operated eye was observed when compared with the unoperated eye. This was independent of the number or type of extraocular muscles operated upon. CONCLUSION It is hypothesised that this chang...
