True about Argyll Robertson Pupil (ARP -Accommodation Reflex Preserved) include the following except: (AIPG 2011)
|A||Absent light reflex|
|B||Preserved consensual reflex|
|C||Preserved near reflex|
|D||Good visual acuity|
Argyll Robertson pupils are bilateral small pupils that constrict when the patient focuses on a near object (they “accommodate”), but do not constrict when exposed to bright light (they do not “react” to light).
is an important diagnostic sign of central nervous system disease—often syphilis.
Holmes-Adie syndrome or disease is a tonic pupilcombined with reduced deep tendon reflexes. In Holmes-Adie syndrome, the pupil(s) don't react to changes in illumination. There may also be problems with accommodation - close-up objects may appear blurry. The pupils are dilated.
a. Marcus Gunn phenomenon (Marcus Gunn Jaw-Winking or Trigemino-oculomotor Synkinesis)
b. CN2 lesion preserves a consensual reflex. CN3 lesion causes dilated-pupil, down-and-out eye, droopy eyelid.
c. Corneal blink reflex is CN5 (V1) afferent and bilateral CN7 efferent.
