When light is shone into right eye, right pupil constricts. Direct reflex of the right pupil is unaffected, The right afferent limb, right CN II, and the right efferent limb, right CN III, are both intact. The left consensual reflex is lost. When the right eye is stimulated by light, left pupil does not constrict consensually. Right afferent ...
Positive Hirschberg sign: the light falls on the centre of the right pupil, but is medial to the centre of the left pupil; therefore, the person in the picture has left exotropia. Synonyms Hirschberg corneal reflex test
The pupillary reflex results in the pupil constricting (left) and dilating (right) These include the pupillary light reflex and accommodation reflex . Although the pupillary response , in which the pupil dilates or constricts due to light is not usually called a "reflex", it is still usually considered a part of this topic.
If there is an efferent defect in the left eye, the left pupil will remain dilated regardless of where the light is shining, while the right pupil will respond normally. If there is an afferent defect in the left eye, both pupils will dilate when the light is shining on the left eye, but both will constrict when it is shining on the right eye ...
A consensual response is any reflex observed on one side of the body when the other side has been stimulated.. For example, if an individual's right eye is shielded from light, while light shines into the left eye, constriction of the right pupil will still occur (the consensual response), along with the left (the direct response).
At least four Purkinje images are usually visible in the normal eye. The first Purkinje image (P1) is the reflection from the outer surface of the cornea. The second Purkinje image (P2) is the reflection from the inner surface of the cornea. The third Purkinje image (P3) is the reflection from the outer (anterior) surface of the lens. The ...
That's right, SMU – which Sunday afternoon raised the profile of a dying conference by securing a precious at-large CFP bid over SEC heavyweight Alabama – is an unpaid intern for a decade.
Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve.. A constriction response (), [1] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.
