Pupillary 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 کاملPupillary 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 reaction in children with recurrent abdominal pain.
Apley, J., Haslam, D. R., and Grant Tulioh, C. (1971). Archives of Disease in Childhood, 46, 337. Pupillary reaction in children with recurrent abdominal pain. An investigation was carried out with 3 groups of children to compare pupillary reactions (as an index of autonomic function) in response to stress induced by the cold pressor test. It was found that normal pupillary reactions are modifi...
متن کاملA trial of objective visual field measurement by pupillary reaction
We created pupil perimetry that could objectively analyze the visual fields utilizing the light reflex with the Visual Evoked Response Imaging System (VERIS). Nineteen hexagonal stimulating elements were used to stimulate up to 15 degrees of eccentricity at 2 Hz. The evoked light reflex was recorded by the infrared camera, and the changes in the maximum transverse diameter of the pupil were mea...
