Do financial relationships with industry
influence physicians’ behavior?
influence physicians’ behavior?
“The present extent of physician-
industry interactions appears to affect
prescribing and professional behavior
and should be addressed at the level
of policy and education.”

Wazana A. JAMA 2000 Jan 19;283(3):373-80
“A minority of doctors (40%) thought
that industry involvement created a
conflict of interest but the majority of
doctors (86%) thought that it did not
create a bias in their own drug
selection.”

Conclusions
•Financial relationships with industry are widespread in the
profession of Optometry, with over 36,000 ODs participating.
•The majority of total dollars paid to Optometrists (72%) goes
to a relative minority of providers (10%).

“Guidelines establishing thresholds,
such as the arbitrary amount of $100,
are based on the belief that there is a
direct “dose response”—that the risk of
bias increases as the value of the gifted
item increases. There is no level,
however, below which it is guaranteed
that marketing wares have no effect on
the recipient.”

an understanding of the ethics of

Relationships with Industry
Optometrists should avoid situations and activities
that would not be in the best interest of their
patients.
Any financial and/or material incentive offered by
industry that creates an inappropriate influence on
an optometrist’s clinical judgment should be avoided
AOA Standards of Professional Conduct
Section E, Part 1-E – Non Patient Professional Relationships
Optometrists should avoid situations and activities
that would not be in the best interest of their
patients.
Any financial and/or material incentive offered by
industry that creates an inappropriate influence on
an optometrist’s clinical judgment should be avoided
AOA Standards of Professional Conduct
Section E, Part 1-E – Non Patient Professional Relationships
Conflict of Interest
The care of a patient should never be influenced by the self-interests of the
provider.
Optometrists should avoid and/or remove themselves from any situation that
presents the potential for a conflict of interest where the optometrist’s self interests
are in conflict with the best interest of the patient
Disclosure of all existing or potential conflicts of interest is the responsibility of the
optometrist and should be appropriately communicated to the patient
AOA Standards of Professional Conduct
Section B, Part 4-B – Nonmaleficence (“do no harm”)
The care of a patient should never be influenced by the self-interests of the
provider.
Optometrists should avoid and/or remove themselves from any situation that
presents the potential for a conflict of interest where the optometrist’s self interests

Questions ?
Questions?
1.) How do the professions of
optometry and ophthalmology compare
with respect to these payments?
2.) Why do you think so much of the
money goes to a relative few
physicians?
3.) Have any optometry schools
instituted policies restricting industry
interaction?

Conclusions
•In both laboratory-cycled and patient-used cases, the
manufacturer-recommended 6-hour neutralization time of
CCP allows for more complete neutralization of H
2
O
2
than the
4-hour neutralization time recommended with PC.
•Both the CCP and PC systems used by study subjects resulted
in higher residual H

concentrations at neutralization time
compared to the systems cycled in the laboratory; however,
the relative increase was larger for PC.

Discussion
•Of the 30-day used lens cases collected, 98.5% of CCP and
20.0% of PC systems at recommended storage time showed
mean residual peroxide ≤ 100 ppm, the ocular detection
threshold.
1
•Further research should be conducted to understand the clinical
implications of these findings.
•Given peroxide solutions are often recommended to sensitive
contact lens wearers, ECPs should consider these findings when
recommending a solution and educating their patients on proper
use.

Cat Scratch Disease (CSD)
•Cat scratch disease (CSD) is a systemic infection caused by the bacteria Bartonella henselae,
with approximately 22,000 cases U.S./year.
1
•Patients contract the infection after being scratched, bitten, or licked by a cat and commonly report a
virus-like illness.
•Demographic: Persons of all ages and ethnicities, but is more often seen in pediatric
populations or those between the ages 30 and 40
•Ocular involvement occurs in ~10% of CSD cases
1,2,5
:
•Parinaud's oculoglandular syndrome: granulomatous conjunctivitis with associated lymphadenopathy
•Focal chorioretinitis
•Neuroretinitis
•Positive Bartonella Henselae titer
•The condition tends to be self-limiting, for a period of eight to 12 weeks, though oral
doxycycline 100mg BID for two to four weeks is widely published as the primary treatment
choice to shorter the duration of symptoms.

Conclusion
•Neuroretinitis is an inflammatory optic neuropathy
characterized by optic disc edema and exudates within the
fovea in a macular star pattern.
•Cat scratch disease is the single most common cause of neuroretinitis.
•Bartonella Henselae Titer confirmative
•False negatives may be present in early disease progression
•OCT and VF analysis are valuable tools that can be used to
monitor disease resolution in cases of Neuroretinitis from Cat
Scratch Disease.
•Neuroretinitis generally has a good prognosis with
spontaneous improvement, but oral antibiotics appear to
hasten recover time.
•Changes in the foveal RPE tend to be permanent and residual “blind
spots” in the vision may persist.
•Having one episode of cat scratch disease usually makes patients
immune for the rest of their lives.

Summary and Conclusions
LBN 0.024% QD in the evening was effective in reducing IOP in subjects with
OAG or OHT with significantly greater IOP-lowering activity compared to
timolol 0.5% BID.
•IOP lowering of 7.5 to 9.1 mm Hg from baseline.
•Statistically greater IOP lowering >1 mm Hg vs. timolol.
•Statistically greater proportion of subjects reached target IOP vs. timolol.
No significant safety findings during the 3 months of double-masked
treatment
•Safety findings consistent with PGAs

•The DOD reported that over 340,000 cases of traumatic brain injury (TBI) were confirmed since
2000, with mild TBI (mTBI) accounting for 82.5%.
•The diagnosis of mTBI has been a challenge for the military primarily because: lack of objective
assessment tools; overlap of symptoms in co-morbid conditions such as post-traumatic stress
disorder (PTSD); interpretation of signs and symptoms by healthcare providers relies on self-
reported symptoms from the injured Warfighters.
•Prompt and accurate diagnosis and management of mTBI generally increases an individual's
prognosis for neurological recovery and safe return to duty (RTD).
•Premature RTD places Warfighters at greater risk of disability if they suffer an additional
concussive trauma.
•Consequently, there is a quest for objective markers (e.g., protein, imaging, cognitive,
neurosensory) to objectively diagnose Warfighters with mTBI/concussion.

reported symptoms from the injured Warfighters.
•Prompt and accurate diagnosis and management of mTBI generally increases an individual's
prognosis for neurological recovery and safe return to duty (RTD).
•Premature RTD places Warfighters at greater risk of disability if they suffer an additional
concussive trauma.
•Consequently, there is a quest for objective markers (e.g., protein, imaging, cognitive,
neurosensory) to objectively diagnose Warfighters with mTBI/concussion.

Gaps
•Lack of objective markers (e.g., protein, imaging, cognitive, neurosensory) to objectively diagnose Warfighters
with mTBI/concussion.
•Ideal tool must be: accurate, quick to perform, non-invasive, causes no discomfort or risk to patient, minimal
training, deployable, and low cost.
•Valid objective markers are particularly important in the field to assist deployed clinicians to make an accurate
determination of fit-for-duty (FFD)/RTD or evacuation.
Objectives

•Since approximately 30 areas of the brain, and 7 of the 12 cranial nerves deal with vision, it is not unexpected
that the patient with TBI may manifest a host of visual problems, such as pupillary deficit, visual processing
delays, and impaired oculomotor tracking and related oculomotor-based reading dysfunctions.
•This study investigates pupillometry, version (i.e., saccades) and vergence (i.e., convergence) eye movements
as potential biomarkers for acute mTBI.
•The study included 3 eye procedures and 1 visual symptoms questionnaire
•10 min test battery.

Questions?
•1: Neuroptics also has a newer version of the monocular pupillometer called NPi-100 that
provides a Neurological pupil index (NPi) used in neurocritical patients as indication of brain
injury severity. Have you considered using the NPi-100 to determine if the patient has a mild
TBI/concussion?
2: Did you look at test-retest repeatability of the pupillometer?
•3: Almost all articles examining the King-Devick as a side-line tool to determine if an athlete
sustained a concussion has a pre-game score to compare to post-injury score. Do you think a
pre-injury score is absolutely necessary to make an appropriate concussion assessment?
