Edge - light pupil cycle time STEPHEN
نویسندگان
چکیده
A thin slit-lamp beam illuminating the pupil margin produces clearly visible pupil oscillations. These oscillations can be timed with a stopwatch, thus producing a measurement of the 'edge-light pupil cycle time'. The pupil cycle time is remarkably stable in various testing situations and is repeatable within about ±3% over extended periods of time. Expected normal distribution and 95 % confidence intervals are given in Table 3. When the iris muscles are normally innervated and responsive, the pupil cycle time is dependent on the speed of nerve conduction and the number and strength of optic nerve impulses. Only 5 % of normal persons aged 12 to 50 years

متن کاملLight Reflex Using Non - Linear Delay - Differential Equations Andr
Neurophysiological and anatomical observations are used to derive a non-linear delaydifferential equation for the pupil light reflex with negative feedback. As the gain or the time delay in the reflex is increased, a supercritical Hopf bifurcation occurs from a stable fixed point to a stable limit cycle oscillation in pupil area. A Hopf bifurcation analysis is used to determine the conditions f...

متن کاملEffects of physical activity on pupil cycle time (PCT) in healthy Indian male.
Globally, physical inactivity is an important risk factor for the development of non-communicable disease consisting of coronary artery disease, as well as, other diseases including hypertension, diabetes, obesity, osteoporosis, and certain types of cancers. Parasympathetic nervous system (PNS) activity in the eye is determined by the pupil cycle time (PCT) can be comparable with cardiac parasy...
