Under normal conditions, when light is shone into one eye,it will cause a direct response in that eye to constrict, and a consensual response in the opposite eye to also constrict. ... Constriction OS (with the light shone into the right eye) would indicate the consensual response of the ...

In older adults, pupils are smaller when at rest in the dark and slower to dilate in response to light. One study measured pupil size at different light levels and across different age groups. The results show that, in the right eye, average pupil size ranges from 2.41 to 5.80 millimeters...
tonic pupila usually unilateral condition of the eye in which the affected pupil is larger than the other, responds to accommodation and convergence in a slow, delayed fashion, and reacts to light only after prolonged exposure to dark or light; see alsoadie's syndrome. Called alsoAdie's pupil...
Using a bright, focused light source, such as a penlight or an ophthalmoscope, thedoctor will begin examining each pupil individually. To assess pupil size and symmetry, the doctor will shine the light into one pupil and observe the response in both. Normally, the illuminated pupil should ...
In the light of the misunderstandings detected in the area of water transport a model based on the physical sciences was designed in the form of an animated film. Pupils taught by this means were able to pick their way through the proposed hierarchy of ideas to construct for themselves a ...
When you're in bright light, itshrinks to protect your eyeand keep light out. When your pupil shrinks (constricts), it's calledmiosis miosis A constriction response (miosis), is thenarrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hy...
Pupils are black because most of the light that enters them is absorbed. Their size changes in response to brightness, as well as certain drugs and emotional and mental states – but their basic form varies greatly among species. House cats...
eye. Generally speaking, the pupils constrict in bright light conditions to allow less light into the eyes and dilate in dim lighting, allowing more light into the eyes and enabling us to see more clearly. Release of adrenaline causes pupil dilatation in the ‘fight/flight/fright’ reflex ...
Pupils dilate in order to let in more light. This is because the pupil is controlled by the sympathetic nervous system, which is responsible for the ‘fight or flight’ response. When the pupil is dilated, it allows for more light to enter the eye and provides better vision in low-light...
