Your superpower Overview

• When to worry, when to watch?

• Worry: Pain, Acute, Ptosis, Diplopia, Bilateral, Trauma, Child

• Watch: Asymptomatic, chronic, isolated, longstanding (FAT scan before CAT scan)

Pupil of the pupil 

Relative afferent pupillary defect (RAPD)RAPD can occur anywhere along pupil pathway on afferent side

Relative afferent pupillary defect (RAPD)

• Objective sign of optic neuropathy if unilateral visual loss

• Not seen in media (cataract) or refractive error 

• Rare in amblyopia (less than 0.3 Log Unit RAPD is rare)

• Size does NOT matter in neuro‐ophthalmic signs (baby RAPD is a sign of a defect in pupillary afferent pathway just like giant RAPD)

Size does not matter…in neuro‐op

Unexplained RAPD (even a baby RAPD) = Worry

“PERRLA” ≠ NORMAL

Worry or watch?

What’s wrong with this picture?

• 60 y/o diabetic man

• New onset ptosis right

• Right adduction, elevation, & depression deficit

• 45 exotropia (XT)

• Diagnosis: “Ischemic third nerve palsy”

• Plan:  “Return 6 weeks”

Acute pupil involved third n. palsyLife threatening diagnosis?

Worry or watch? I tell our technicians….

• If the patient’s complaint is diplopia or ptosis or….

• If you have to lift a ptotic lid to put in the dilating drops then….

• STOP, come get the doctor before dilating

Rule of the pupil

• A pupil involved third nerve palsy

• Aneurysm of  posterior communicating artery until proven otherwise

There is no “I” in “TEAM” and….

•There is no “A” in “MRI”

Summary of Pupils of the Pupil

• When to worry, when to watch

• Worry: Pain, Acute, Ptosis, Diplopia, Bilateral, Trauma, Child

• Watch: Asymptomatic, chronic, isolated, longstanding (FAT scan before CAT scan)

Your superpower

Ms. Flaherty is a Certified Ophthalmic Medical Technologist at Stone Oak Ophthalmology in San Antonio, Texas.

Ophthalmic Professional, Volume: , Issue: August 2012, page(s):

The hero in you

• Ms. Flaherty saw a “red eye” patient

• Headache

• Ptosis

• Smaller pupil

• Diagnosis of Horner syndrome

• MRI head/neck: carotid artery dissection & pseudoaneurysm

• Patient wanted to go his family reunion but Ms. Flaherty convinced him to go to hospital where neurosurgery treated dissection

Three months laterNote from the neurosurgeon to Ms. Flaherty

• "Your patient's dissection has resolved.“

• There is a small pseudoaneurysm, but this should not pose any significant stroke risk to him. 

• I will follow up with him in three months with an MRA. 

• I again related to him how lucky he was to have you evaluate him initially and to very promptly identify his problem."

Ms. Flaherty comments

• It is this episode in my long career in ophthalmology that I am most proud of being a JCAHPO Certified Ophthalmic Medical Technologist. 

• I can say that this was the first and only time in my career I have ever seen a Horner's Syndrome and I was happy I could identify it. It helped save a life.

• Our patient will be attending many future family reunions and, as for me, I will never forget having had a small hand in making that possible.

Why are we here?....

Thanks for your attention Thank you…
