Eye examination of a person reveals near reflex to be present but light reflex is lost. What is this condition known as?
Argyll Robeson pupil - Seen in neurosyphilis Bilateral constricted irregular pupils Light reaction is absent and accommodation reflex is present (ARP - Accomodation reflex present and PRA - Pupillary reaction absent) Marcus gunn pupil Seen in optic neuritis Swinging flash light test - light is flashed on one pupil and constriction is noted and than light is moved to the contralateral pupil and response is noted . normally both pupil constrict equally . in unilateral optic nerve disease when light is transferred to the diseased eye both pupils will dilate and on swinging back to normal eye both will constrict Adie Holmes pupil is a tonic pupil seen in young women with vermiform sluggish pupillary constriction not absent pupillary reflex Oculomotor palsy will have the final efferent pathway affected - hence both pupillary and accomodation reflexes will be absent
