The Dry Eye Summit 2014:
How Did We Develop
Recommendations?
• Current guidelines (eg, DEWS, AOA) are
perceived as being too complex or inaccessible
• Discussed clinical data on dry eye disease and the
role of ocular surface wellness
• Limited awareness of guidelines
• Identified current gaps in management through
survey sent to “experts” and >1000 ECPs
• Recommendations from “the experts” are not
being incorporated into everyday practice by
community ECPs for multiple reasons
• Need to SIMPLIFY by setting minimum
recommendations that all ECPs can commit to
Recommendations from the Dry Eye Summit 2014
Identifying Gaps in Care:
“Expert” vs Community ECP
Practices
For What Percentage of Your Dry Eye Disease Patients
Do You Recommend Any Treatment?
• 1.5-day discussion and debate (ECPs and industry)
on best practices for screening, diagnosing, and
managing dry dye disease
• Used interactive polling system to establish
consensus
(minimum 2/3 agreement needed)
Recommendations from the Dry Eye Summit 2014
Know the Risk Factors
• Disease
– Diabetes
– Allergies
• Contact lens wear
• Medications
– Antihistamines/Decongestants
• Age
• Digital device use
– Cell phones
– Tablets
– Computers
Experts are much more likely to recommend treatment for dry eye disease.

Prevalence of MGD and Lipid
Deficiency1
Meibomian Gland Dysfunction:
A Prevalent Condition with Consequences
“Meibomian gland dysfunction (MGD) may well
be the leading cause of dry eye disease
throughout the world.”1
-The International Workshop on Meibomian Gland Dysfunction: Executive Summary
MGD is present in ~37% of entire ophthalmic practice
patients and ~47% of optometric practice patients.2

Posterior Blepharitis (MGD):
Etiology
Tear Composition
1.
Prevents evaporation of tears
and is the final optical
interface
2.
Hydrates and provides optical
interface
Change in composition of meibomian gland
secretions that leads to inflammation, irritation
and an altered tear film
Normal secretions convert from unsaturated
lipids (that melt at body temperature) to
saturated fats

Adheres to cornea and binds
aqueous

Posterior Blepharitis (MGD):
Etiology
3. The mono- and diglycerides are more solid in
composition, leading to obstruction/plugging of
the meibomian gland
4. The mono- and diglycerides are proinflammatory, leading to the inflammation
associated with MGD
Consequences of MGD
Obstruction of the gland leads to phases of downstream
consequences, resulting in decreased availability of meibomian
lipids at the lid margin and tear film
Partial obstruction
Initial phases of MGD
• Partial obstruction
• Primary consequence of low delivery
of oil
Progression towards total obstruction
• Stasis of meibum inside the glands
increases with increased pressure
• Resultant dilatation
• Acinar atrophy
Total obstruction
As total obstruction is approached, all
factors are exacerbated, leading to
glandular atrophy and loss of function

Involves degradation of triglycerides to
mono- and diglycerides
Lipases appear to be involved in the
degradation
Pathophysiology

Irregular oil pattern disrupts tears

Why Measure Tear Osmolarity?
Measuring osmolarity allows us to evaluate an actual physiologic marker rather than a “sign” of the disease such as staining or tear break up time.

Differential diagnosis tests
 Tear Break Up Time
 Corneal FL Stain
 Lissamine Green Staining
 Schirmer
 Meibomian Gland Expression
 Trans-illumination
 Osmolarity
 Inflammadry

Dry Eye Disease Can Decrease Visual Acuity
and/or Quality of Vision
Two Numbers Crucial to Understand Osmolarity The MAXIMUM of the two eyes:
The DIFFERENCE b/w two eyes:
Tears higher than 300 mOsm/L This shows the stability of the tear demonstrate loss of homeostasis film. Normal tears are stable and and likely become pathogenic > 308. < 300 mOsm/L bilaterally. A difference of > 8 mOsm/L is a hallmark of tear instability.
What if TO is elevated but the ocular surface is quiet and/or the patient is asymptomatic?



Hyperosmolarity is a hallmark sign of DED as stated in dozens of peer review publications over the past 5 years and even decades of research prior to the development of TearLab (> 250 publications)
The patient may not have reached a point where visible evidence is present e.g. corneal staining which is typically a late sign for DED and can also be present in other OSD conditions
We now are seeing many publications showing hyperosmolarity can cause damage to corneal nerves leaving a neurotrophic condition with poor symptom recognition
What if TO is normal but the ocular surface and/or symptoms indicate dry eye? 

Signs and symptoms do not correlate with each other and this also includes osmolarity There is significant overlap with other OSD conditions such as ocular allergy, conjunctival chalasis, etc. It is highly unlikely that the TearLab system will show a false positive reading
Subjectivity of patient symptoms (e.g. stoic vs. whiner)




Hyperosmolarity is a central pathogenic factor in DED
Hyperosmolarity is more prevalent than previously thought
 About 25% with moderately elevated levels
Many symptomatic patients do not actually have DED and thus don’t respond to therapy
Elevated osmolarity and tear film instability define DED:
 Low and stable osmolarity indicates the ABSENCE of DED
 Elevated osmolarity and/or an inter‐eye difference of >8 mOsm/L indicates tear film instability and early manifestation of DED
Osmolarity is the best single predictor of DED severity
Tear osmolarity is a leading indicator of response to therapy

MMP-9 in Tears
Matrix metalloproteinases (MMP) are proteolytic enzymes that are produced
by stressed epithelial cells on the ocular surface.1
MMP-9 is a non-specific inflammatory marker that plays a critical role in
wound healing. 1
Normal, healthy range is between 3-41 ng/ml
Dry eye (ocular surface disease) demonstrates elevated levels of MMP-9 in
tears1
MMP-9 is a more sensitive diagnostic marker than clinical signs and
correlates with clinical exam findings1
Increased MMP-9 in dry eye leads to visual morbidity2
Deranged corneal epithelial barrier function
Increased corneal desquamation
 Corneal surface irregularity

Importance of Detecting MMP-9
Identifying elevated levels of MMP-9 facilitates better
management of:


Patients who present with signs or symptoms of dry eye
Patients having ocular surgery such as LASIK or cataract surgery
When elevated levels of MMP-9 are not identified,
confirmed, and treated prior to ocular surgery, the following
complications may occur:

InflammaDry 4-Step Process
Using 4 simple steps, InflammaDry® test results can be achieved in
just 10 minutes, aiding in the diagnosis of dry eye before the patient
leaves the office.
Step 1: Collect the Tear Sample
Instruct the patient to look up (A) and gently lower the eyelid to expose
the palpebral conjunctiva (B).
Dab the sampling fleece in multiple locations along the conjunctiva
(C), releasing the lid after every 2-3 dabs to allow the patient to blink
(D).
After completing a minimum of 6-8 dabs along the conjunctiva, allow
the sampling fleece to rest along the conjunctiva for an additional 5
seconds to ensure saturation (E).
Inspect the sampling fleece; when a sufficient tear sample is collected,
the fleece will glisten (F). The fleece may be white or patchy pink in
color, depending on the patient’s tear composition. If the fleece is not
glistening, repeat the process.
*
Step 2: Assemble the Test
Gently place the sampling fleece of the sample collector
into the sample transfer window of the test cassette.
Press firmly where indicated.
A double-click means the test is properly assembled.
Step 4: Read the Results
Wait a minimum of 10 minutes
before reading test results.
The control line appears in the
control zone and must appear
for the test to be valid.
If the test is negative after 10
minutes, allow an additional 510 minutes before reading test
results.
Read any form of a red line,
whether faint, broken, or
shadow, as a positive test result.
Step 3: Run the Test
Immerse the absorbent tip into
the buffer vial for a minimum of
20 seconds, until a purple fluid
wave is observed moving across
the result window.
Remove the absorbent tip from
the buffer vial, replace the
protective cap, and lay the test
flat on a horizontal surface for 10
minutes.
Internal Procedural Controls
InflammaDry
has built-in
procedural
controls.
Check these
controls for
the first
sample tested
each day.
Two faint orange lines
appear on an unused test
When the test is activated
a purple fluid wave runs
through the window
The presence of a blue
control line indicates that
the test is valid.

Tips for Success
Tips for Success
InflammaDry should be performed PRIOR to instilling
ocular anesthetic, topical dyes, or performing Schirmer
testing.


Reduce false negatives by:


If drops are used, wait 2 hours before collecting a tear
sample.
InflammaDry should not be used within 20 minutes of
performing a Schirmer tear test.



The opened test cassette should be used within 1 hour.
Wait the entire 10 minutes of development time before
reading test results.


If the test is negative after 10 minutes, allow an additional 510 minutes before reading test results.
Reduce false positives by:

Read any form of a red line, whether light or broken, as a positive result.

Passive vs. Active Therapies
Passive is a single-action therapy that may reduce inflammation but may delay healing
• Therapeutic Contact Lenses are a Passive Therapies
•
•
Provide mechanical protection
May induce infection
• Steroids/ NSAIDs are Passive Therapies
PROKERA®
•
•
Biologic Corneal Bandage
Reduce inflammation
Delay healing/ flare-up infection
Active is a dual action therapy that controls inflammation & promotes scarless healing
•
PROKERA® is an Active Therapy (Biologic Corneal Bandage)
•
•
•
•
Controls inflammation
Prevents additional damage
Promotes and accelerates wound healing
Prevents / reduces scar formation
Active vs. Passive: The Difference Is Clear

How do I know when to remove
PROKERA®?
• Determining when to remove PROKERA® is patient and
case dependent
• Follow your usual protocol for follow ups
• Fluorescein staining can be used while PROKERA®
remains on the eye to determine healing progression
• Expect to see the amniotic membrane in PROKERA® to
Lower Lid Tightening for Ectropion
thin when
• Significant inflammation is present
• There has been over exposure to air

Case Study 1:
Recurrent Corneal Erosion
52 year-old female presented with ocular pain and blurred vision (20/200) for
2 weeks. She had a history of similar attacks & diagnosed as RCE. Epithelial
debridement, lubricants, and BCL failed to relieve pain and halt recurrence.
Treatment Strategy
 Epithelial debridement to remove
loose epithelium (Fig. A, B) followed
by placement of PROKERA® SLIM
 On the 2nd day, the patient had no
pain. Complete healing occurred
within 3 days, resulting in clear
cornea, 20/20 vision. A smooth
surface remained stable with no
recurrence for 13 months follow-up
(Fig. C, D)
PROKERA® Summary

Active Amniotic membrane modulates healing towards regeneration,
away from inflammation /scarring

CRYOTEK™ maintains tissue structure and healing biological properties

PROKERA® when used early reduces inflammation and minimizes
scarring to prevent sight threatening complications

PROKERA® is the only FDA-cleared therapeutic devices that
simultaneously reduce inflammation and promoting “regenerative/scarless
healing”

PROKERA® is a self retaining biologic corneal bandage that can be easily
inserted in your office

Use CPT Code 65778 for in-office reimbursement of PROKERA®
PROKERA® should be considered after lubricants have failed.

Ophthalmology Management-September 2013”Tear film can be the most important part of the
eye, and instability diminishes performance of a
multifocal lens. In fact, reports have shown that
patients without dry eyes placed on cyclosporine
two weeks pre op and three months post op had
better vision and more ocular comfort”
