Marcus Gunn Pupil
- pupil of the affected eye will ____ when illuminated
- dilate

fails to constrict when illuminated
pupillary escape
a difference of 1/2mm between 2 eyes
essential anisocoria
adie’s tonic pupil

Marcus Gunn Pupil is also known as
afferent pupillary defect
Marcus Gunn Pupil use:

- Consensual test
- Swinging Flashlight test
Swinging Flashlight test
Horner’s syndrome is characterized by the following EXCEPT:
- miosis
- mydriasis
- ptosis
- enophthalmos
- anophthalmos
- decreased in facial sweating on affected side
- mydriasis
* anophthalmos
ocular sympathetic fibers is responsible for:
- pupillary dilation
- pupillary constriction
pupillary dilation
Hutchinson’s pupil
- dilated pupil
- constricted pupil
dilated pupil
Hutchinson’s pupil
- unilateral
- bilateral
unilateral
Hutchinson’s pupil due to

- peripheral nervous system (PNS)
central nervous system (CNS)
Hutchinson’s pupil compresses the:
- iris
- ciliary body
- macula
- optic nerve
optic nerve
It is a condition were the pupil does not react to light, but it does react to accommodation
- hutchinson’s pupil
- pupil near dissociation
pupil-near dissociation
It is a condition were the pupil does not react to light, but it does react to accommodation
