Even if you have an excellent doctor treating you for Dry Eye or meibomian gland dysfunction (MGD), there are lifestyle changes you can make to help improve your symptoms. These range from getting a good night’s sleep to washing your hands before touching your eyes. Some lifestyle changes can be hard to make. But when the discomfort from Dry Eye or MGD takes over your life, even small changes can add up to make a big difference. Remember, you can play a big part in managing Dry Eye and MGD symptoms.

1. Sleep with moisture chamber goggles.

If you have aqueous deficiency, MGD, or sleep with your eyes opened (nocturnal lagophthalmos) moisture chamber goggles can help to prevent your tear film from evaporating. Choose goggles that block out light or clear ones that you can see through. Be sure to wash them every day according to the manufacturer’s directions. If your goggles are uncomfortable, contact the manufacturer. If the pair you have is under warranty you should be able to exchange them for a more comfortable pair.

2. Don’t touch your eyes unless you have just washed your hands.

Introducing bacteria to the eyes only exacerbates symptoms. So wash your hands right before you touch your eyes for any reason, even when you’re just putting in an eye drop. And blot them dry them with a fresh, clean, low-lint paper towel. Keep a roll of paper towels on your bathroom counter or wherever you take care of your eyes most often so they are always within reach when you need them.

3. Avoid foods that cause inflammation.

Some foods are known to cause inflammation such as foods that contain high levels of Omega 6 fatty acids. This includes chicken and turkey. Inflammation is not always a bad thing – it’s how the body fends off disease. But chronic inflammation, which is associated with MGD, is the last thing you want to increase when you’re trying to improve eye comfort. Some experts recommend eliminating dairy, sugar, and wheat. But without actual food sensitivity testing, you might be eliminating some foods unnecessarily while not eliminating foods that cause your inflammation. For more information, see our page on food sensitivity testing.

4. Eliminate allergens.

Allergens cause allergic reactions and inflammation, and inflammation is the enemy of the meibomian gland. See tip #3 above. Eliminating allergens completely can be very difficult. For example, dust is almost impossible to completely eliminate or avoid. And it can be extremely difficult, and even heartbreaking, to eliminate it if the allergen is a beloved pet. But the more you can avoid allergens, the less you will exacerbate any symptoms.

5. Increase Omega 3 consumption.

Adding Omega 3 to your diet helps to offset the inflammatory effects of Omega 6’s. You can either increase the foods that have a beneficial Omega 3 to Omega 6 ratio or take a good Omega 3 supplement. If you choose to take an Omega 3 supplement, be sure it’s tested for contaminants.

6. Stop wearing eye makeup.

If you’re used to wearing eye makeup, stopping can be very hard. It might take some extra courage to go out without any on. But tiny particles of eye makeup can flake and fall into the eyes. Powders can rim the eye lid margin, the site of the opening of the meibomian glands. Makeup brushes, sponges, and mascara tubes harbor bacteria. And we don’t even want to imagine the colonies of demodex mites in there, so on to the next tip.

7. Get a good night’s sleep.

Eye tissue is restored when we sleep. When we don’t get a full eight hours, the cells don’t have time to regenerate and we end up exacerbating any eye discomfort. Eight hours is usually recommended. So put on those moisture chamber goggles and go to bed early.

8. See your doctor. Don’t delay.

Doctors can’t help if they don’t know what’s going on. So if you’re not getting better, or you’re experiencing some new symptom, don’t delay and make an appointment. Some doctors will communicate via text or e-mail once you’ve established a doctor/patient relationship. They may even take your call, especially if you’re experiencing acute symptoms. So if you’re experiencing something new, or something you’re pretty sure shouldn’t be happening, let your doctor know. The sooner the better, and before it gets worse.

Managing Dry Eye and MGD symptoms can be challenging, but remember that every little thing you do can add up to help a lot.

If you’ve had your meibomian glands probed, you probably remember hearing loud “pops” as the probe pierced through a band of fibrotic tissue (periductal fibrosis) somewhere along the length of the gland. Or it could have felt as if the probe was passing through several bands of fibrotic tissue, producing a gritty sensation and a sound like a short machine gun round.

Of course there was no machine gun.

The pop was just amplified in your head, the way a tuning fork can seem very  loud when it’s held up to your ear, or the way flossing your teeth can seem very loud, but only to you.

The doctor can also feel the fibrosis with the probe as it meets resistance. And he feels a “pop” or something “gritty” when the probe pierces through.

Pop, Gritty, and Periductal Fibrosis

Given how many of us who have been probed have heard and felt “pop” and “gritty,” it’s puzzling that a recent paper published in Bio Med Central Ophthalmology completely misses this essential aspect of meibomian gland physiology and dysfunction (MGD).

The paper claims that evaporative dry eye is thought to be caused by “ductal hyperkeratinization, plugging and obstruction” but doesn’t discuss the role of periductal fibrosis in MGD, something that hyperkeratinization may cause indirectly through obstruction and meibum stasis (stagnation) with inflammation.

(Keratinization is the production of keratin, a protein, by ductal epithelial cells. In meibomian glands, this happens in the cells lining the ducts and at the opening. Hyperkeratinization refers to an excessive production of keratin by these cells. Too much keratin blocks the normal flow of meibum, leading to obstruction, stagnant meibum, inflammation, and eventually periductal fibrosis).

We’re not disputing the fact that hyperkeratinization occurs in meibomian glands. It does. But missing is what it may cause, or what may develop concurrently, from any cause of inflammation – periductal fibrosis. Missing periductal fibrosis means missing an essential fact of MGD, a fact that can alter greatly diagnosis and, ultimately, treatment.

Because if you don’t accept that there’s fibrotic tissue inside the gland, which can be caused by numerous factors that involve inflammation, you’ll never comprehend why probing is an essential treatment. You’ll believe that all you need to do is clear the stagnant and hyperkeratinized cells with warm compresses and lid massage. And you’ll completely miss the fibrotic tissue that can neither be heated, nor massaged, away.

That fibrotic tissue requires a completely different treatment approach – a tiny probe the width of a hair to pierce it.

Question:
Pop, Gritty, and Probe” is very interesting. Does the probing take care of the problem forever or is it necessary to repeat it and how often? Can the block be prevented or at least its build-up slowed down? If so, is there a self-help approach that the doctor could recommend?
Walter, New York

Answer:
Walter, we posed your question to Dr. Steven Maskin. He said:

Probing establishes that the meibomian gland duct is opened. Repeating the procedure is not always necessary, but this depends entirely on the patient and any other conditions or co-morbidities they may have which creates inflammation leading to periductal fibroses and re-obstruction. Our studies show that about 33% of lids are reprobed at an average of 18 months with 67% reprobed at average greater than 2 years. Any other conditions that may cause inflammation of the meibomian glands should also be treated at the same time, including aqueous tear deficiency, or allergies that may require topical treatments, infections, or infestation by demodex mites. Other considerations include oral medications such as Periostat (doxycycline) that can reduce inflammation, supplementation with Omega 3 fatty acids which may reduce inflammation and improve the quality of the meibum, and systemic treatments for autoimmune conditions that can cause systemic and periglandular inflammation. If it is well tolerated and there are no contraindications, warm compresses that can be done easily at home can help to liquefy the meibum, helping to prevent meibomian gland obstruction.

Dr. Robert Wachter gets our vote.

At TEDMED 2015 he told the audience that professional intuition is under assault.

That’s how we feel when some doctors disparage meibomian gland probing, saying it’s too new or citing a lack of evidence as the reason why they’re against it, even while we’re sitting in front of them with our probed (and now functioning) meibomian glands.

When they say it’s too new, we say yes, probing might be relatively new. But just because it’s new, doesn’t mean it doesn’t work. Because the way we see it, newness and effectiveness are not mutually exclusive. Besides, meibomian gland dysfunction (MGD) has been around a long time. There’s nothing new about that disease.

Common Sense, Intuition, and MGD

And, fundamentally, doesn’t it just make sense that if a meibomian gland is blocked (think periductal fibrosis – vascularized bands of tissue around the duct that constrict it) something (dare we say a probe?) would need to pierce through that blockage to open up the gland, the way a balloon angioplasty widens and clears obstructed and constricted veins or arteries? So to us, meibomian gland probing as a treatment is obvious, and intuitively makes sense.

And even if it is relatively new, that doesn’t mean there isn’t any evidence of its effectiveness. Its inventor, Dr. Steven Maskin, has plenty of evidence. Plus other independent studies have been conducted all over the world – Japan, Spain, China, Russia, New York State. A double-blind clinical trial was even completed at Harvard last year, but the results haven’t been published yet. (Let’s hope competing interests aren’t suppressing its publication – which, sadly, sometimes occurs in the medical field).

Because, although there’s a place for evidence-based medicine, there’s also a place for intellect, experience, wisdom, common sense, and intuition – elements of science and medicine at their best.

After all, once upon a time, nothing was “evidence-based.” Not even an aspirin.

We’re pleased to learn that after five years, PROSE lenses, a type of scleral lens fitted at Boston Foundation for Sight, are still helping about ¾ of the people who have them and who suffer with Dry Eye.

And we’re not surprised at the results of the review in which researchers confirmed that:

73.6% of patients were wearing the devices at five years. Patients with a distorted corneal surface were more likely to continue using the PROSE device than were those with ocular surface disease (84% vs. 64%, p=0.0121).

Ocular surface disease, a term sometimes used in place of Dry Eye, can manifest in many ways. About 80% of the time it is due to meibomian gland dysfunction (MGD). That’s why treating the meibomian glands, with probing or other interventions, is so important in the treatment of Dry Eye. This may also be why some people abandon scleral lenses, because the lenses aren’t treating an underlying condition that can cause extreme discomfort. Wearing the lens can even exacerbate discomfort in these cases.

Microbiome of Contact Lens Wearers Studied

Still 74% is significant. Though some of those patients may have other co-morbidities that still need to be treated e.g. the often missed conjunctivochalasis or SLK. For patients with these co-morbidities, scleral lenses may indeed provide relief from pain and discomfort (as long as they can tolerate something in their eyes) but without addressing the underlying cause of their pain.

Even though some patients are able to resume normal activities after being fitted with scleral lenses, a recent study discovered that the microbiomes of the eyes of contact lens wearers differ from the microbiomes of the eyes of those who don’t wear contact lenses. And an altered microbiome may increase the risk of eye infections in contact lens wearers. So to prevent infections, scleral lens wearers should practice good contact lens hygiene.

We came across this story today:

New research reveals an alarming, self-acknowledged gap in family doctors’ skills when it comes to diagnosing and treating patient’s eye conditions.

The Vision of Britain report, commissioned by Optegra Eye Health Care, shows that more than three in 10 GPs (32 per cent) say they feel ‘de-skilled’ in diagnosing eye conditions, reflecting the immense pressures and workload on these doctors.

And 44 per cent of GPs say that they feel less confident in dealing with eye conditions than any other part of the body.

Yet more than a quarter of British adults (26 per cent) turn to their GP, rather than an optician, for help if they have an eye problem.

Two in five GPs (40 per cent) surveyed for Vision of Britain state they need more, or refresher, training on all eye conditions.

Dr. Sarah Jarvis, GP and medical broadcaster, says: “As a doctor, I’m only too aware of how little in-depth training I had in dealing with everyday eye problems like dry eye and short-sight. Yet they affect so many patients. It is vital that GPs on the frontline have ongoing support in diagnosing their patients accurately and confidently so they can be put on the right treatment path.

That’s great. Let’s hope the UK’s general practitioners are open to receiving training that covers the entire spectrum of Dry Eye diagnosis and treatment, from mild to severe and everything in between. And then let’s hope that training is expanded to eye doctors.

Value-based care, a new buzzword describing mechanisms to reduce the costs of healthcare, is something many of us are already all too familiar with.

Consider this hypothetical cost-cutting scenario described by a health policy expert:

If a patient says he would like an MRI performed, the physician can refer to the list of recommendations and explain that there is insufficient evidence to suggest an MRI is necessary at this time. The physician may then suggest lower-tech interventions such as physical therapy or over-the-counter pain relievers.

In our opinion, the policy expert has fundamentally missed the point. The patient asking for an MRI isn’t asking for intervention. The patient is asking for a diagnosis. Neither physical therapy nor pain relievers are a diagnosis.

Are doctors really going to be willing to take this “value-based” approach?

Sadly, for many Dry Eye patients, this fundamental first step, the right diagnosis for Dry Eye symptoms, is often skipped.

The Right Diagnosis for Dry Eye Symptoms

We don’t know why exactly but suspect that it may be due to the fact that many (most?) ophthalmologists are following the “preferred practice pattern” guidelines promoted by their accrediting body, the American Academy of Ophthalmology. Unfortunately for these doctors and for us, the guideline is outdated, reducing the likelihood that we’ll be diagnosed properly. And then we’re all given the same standard treatments appropriate perhaps for only mild cases (lubricating drops, warm compresses, lid wipes) and Restasis.
But if we don’t respond to these standard treatments, our symptoms are labeled phantom, psychosomatic, secondary to depression, or neurological in nature.

Instead, doctors should examine each of us thoroughly as individuals, not as populations, and then address each diagnosed co-morbidity with targeted treatments, the way some doctors do.

That would be real value-based care, care based on a specific patient’s needs, starting with a right diagnosis.

One of the reasons we started the Not A Dry Eye Foundation was the frustration we felt when confronted by physicians who dismissed our symptoms as being “something we would learn to live with” or “all in our heads.” Not only were we mystified by their (lack of) diagnosis and conclusions, but we were terrified at the prospect of having to live with unbearable eye pain for the rest of our lives, and this without anyone telling us the causes of Dry Eye pain.

When we eventually learned about the ways the disease can quickly escalate and the way it can alter the tissue, secretions, and functioning of various eye structures, we felt vindicated. We knew all along that nothing that we were experiencing was psychological, neurological, or psychosomatic in nature. It was physical – blocked meibomian glands, inadequate aqueous tears, wrinkled conjunctiva, bacteria, twisted lashes, demodex mites, allergies, and more.

Learn about the causes of Dry Eye pain

And there was a lot that could be done about each of these conditions so we wouldn’t have to learn how to live in extreme, debilitating, and unbearable pain for the rest of our lives. There was probing for obstructed meibomian glands, punctal cautery for aqueous deficiency, surgery for the wrinkled conjunctiva, antibiotics for infections, epilation for misdirected lashes, and any number of medications or other treatments for anything and everything else.

But with all of these possible diseases taking hold in the eyes at the same time, is it no wonder that we felt pain? If a single eye lash can stop us cold, why wouldn’t a host of diseases cause unbearable pain in the most sensitive part of the body?

Dubious Causes of Dry Eye Pain

And so we became frustrated once again when we learned that physicians at a prominent teaching hospital and a VA hospital concluded that “neuropathic ocular pain due to Dry Eye is associated with multiple comorbid chronic pain syndromes.”

To us, this is like saying that when you have a diseased finger and are experiencing pain in that finger, the pain is due to some other chronic pain syndrome, not to the disease in your finger.

What?

We wonder if the authors will next conclude that the treatment should be Lyrica or some other anesthetizing pain medication? Or maybe serum tears? Or scleral lenses?

Maybe.

But we think there’s a much better approach.

It has to do first with correct and comprehensive diagnosis, the most important step in alleviating symptoms, and then targeted therapy for each co-morbidity — the approach taken by our doctor, Dr. Steven Maskin.

And so we conclude by citing a different study by some of the same physicians at the same teaching and VA hospitals who concluded that ocular pain associated with Dry Eye may be due to conjunctivochalasis, and that patients should be screened for the disease.

Now we’re getting somewhere. That’s the spirit. Happy New Year!
