New Research Leads to New Approaches to Dry Eye Treatments & Managements

“The more we learn about dry eye, the more we need to understand and use the appropriate treatment for different disease entities”. 

Dry eyes are classified as Ocular Surface Disease.  Today’s eye doctors are faced with a great deal of uncertainty. Options for treatment are actually getting more restricted due to domination by prescription drugs which increased the cost of dry eye treatment in recent years by many folds.  The default treatment by eye drops no longer work.

It is well known that frequent use of eye drops make your eyes drier.

What do we know about tear film and mucin?
Some of the new research in dry eye made a big difference in our understanding of dry eye disorder. For example, the tear film, once thought to be 7µm in thickness and three layers thick (mucin, aqueous and lipid), it is now generally accepted the tear film is 3µm-to-4µm thick, and there are two layers: a mucin-aqueous gradient “gel” and a lipid layer.  This changed our ability to accurately measure tear film thickness with interferometric techniques, which have been confirmed with anterior segment OCT scanning.

We also now have a better understanding of mucins—MUC 16 is not a membrane-bound mucin and therefore, is mobile and capable of forming a gradient in the aqueous layer. This allows the formation of “crusty” build up on eye lids - Blepharitis.

How  mucin plays a role in the health and disease of the ocular surface is still do not well  understood, but new research providing insight does increase our knowledge of mucin biology to better manage dry eye syndrome.

Today’s Patients Are More Informed, and Demand Better Answers!

Today, consumers are more knowledgeable and want better answers.   Direct-to-consumer marketing, the Internet and education all result in increased awareness of disease states by both patients and clinicians.  Doctors are influenced by supportive science for therapeutics, clinician practice patterns, education and peers. Doctors are trained a certain way in medical schools, and tend to stay with the way they were taught- slow to change. However, today’s patients demand more. Patients in this case, can be a great asset and advocate to their doctors -provide them with more options! TheraLife 's natural remedies is one of these new approaches that do not fit the traditional way of thinking.
What is Ocular Surface Disease? 

Ocular Surface Disease is composed a family of conditions impacting the front of the eye. Terms such as blepharitis, meibomian gland disease or dysfunction (MGD), keratoconjunctivitis sicca, meibomitis, and meibomian keratoconjunctivitis, among others, led to the concept of dry eye disease and no less than 10 different classification schemes for some component of dry eye or blepharitis through the years.

How to Diagnose Dry Eye?
The problem is there is no single accepted diagnostic test for dry eye and the tests.  What tests are done often correlate poorly with symptoms. It is suggested that doctors ask a series of questions in addition to some of the more accepted conventional tests for dry eyes:
  • Schirmer’s Test –to measure tear volume
  • Tear Breakup Test- to determine tear viscosity
Your eye doctors should: 

1. Ask about symptoms. Have the patient describe in his/her own words how his/her eyes feel, when they feel the worst and how it is impacting his/her life. Record this information, and refer to it at follow-up visits. Note current treatments, including frequency of application.

2. Look at the lids. Twenty years ago, we looked at the lids, but at some point, we stopped. Start to express the meibomian glands- squeeze fluid out. If you see a blocked gland on slit-lamp evaluation in symptomatic patients with quiet lids, you will be surprised by what you find. Be patient—press, move laterally, press, move back, re-press. Look at the quality of the secretions, and record your description.

3. Stain. Most practitioners use fluorescein to assess tear break-up and staining of the cornea. Wait at least one minute before fully evaluating corneal staining. Believe me, you will see more. Then, use lissamine green, and again, wait a minute or two before you observe the ocular surface. This dye takes time to color mucin and devitalized cells. A band-like pattern across the inferior third of the cornea usually means either incomplete blink or possible MGD. A new product, Fluramene (Noble Vision Group), can do the job of both staining agents with one drop.

4. Follow up. This takes valuable chair time, but is worth it in the long run. Recently, there has been a lot of discussion among clinicians with dry eye clinics about the best time to follow-up on a dry eye or MGD patient.

Get Your Doctor to Take Time for You Your doctor should take time to do the proper medical exam and provide sufficient information for you why certain decisions are made.

We hear all too often that the doctors are doing the minimal, do not take time to explain to the patients what is going on with their debilitating dry eye conditions – leading to much frustrations on both patients and doctors.
