Now there are over 20 categories of treatment options for patients, each with their benefits and risks; some covered, others not covered by insurances; some FDA approved and some very experimental and in its infancy. Few have been studied in depth, and with the recent results of Omega 3 intake–long a solid treatment suggestion by MDs and ODs alike—the use of all treatment options for dry eye could theoretically be called into question: few studies have controls and it is time consuming to truly find the type of controls needed for most of these studies.
Many patients have asked me to give the the full list of options so they can think about it. Some patients hate having to choose and find such list overwhelming.
What is the best way to educate patients on their options without overwhelming them.
Here are the 3 options we have worked on, one with Dr. Andrea Kossler’s (head of Oculoplastics at Stanford and my wonderfully smart little sister) help.
No matter what we have tried: they are overwhelming sheets. But still most patients want what we talked about written down so they can think about it.

This was my original Step Ladder approach to explain Dry Eye options: You start from the bottom and move up as needed or jump to move up higher if needed.
This is a sample of the sheet I give to my patients.
This is part of the Review Sheet I give to my patients that was developed by Dr. Kossler & Perlman. I modified it for my patients. Still a lot of information.
Finally, this is a sample of what I fill out when patients come to see me so I can keep track of what has worked for them and what they should try next.
We are working on one more patients can fill out and I can update on what we agree the patient should try next.
Most MDs and ODs will still continue to recommend increased Omega 3 intake for most patients in their natural food choices as Omega 3 has been shown to be helpful in many conditions. The cause of dry eye is multifactorial and the effectiveness of treatments are influenced by many factors. As with many studies, it is likely it would take thousands to tens of thousands of patients to show an positive effect of Omega 3 intake on dry eye. I have many patients who say they notice an improvement on Omega 3: is that true or a “placebo effect”? I do not know. Still, it is possible Omega 3 intake does help certain patients outside of a “placebo effect.”
Personally, I always choose the organic, wild salmon when given a choice at dinner. I try to increase my Omega 3 intake as naturally as possible for general health reasons.
Should MDs and ODs recommend Omega 3 pill intake still? This is a tough one. It will depend on the patient.

OMEGA-3S FROM FISH OIL SUPPLEMENTS NO BETTER THAN PLACEBO FOR DRY EYE
NIH-funded study finds omega-3 fails to yield beneficial results in the clinic
Omega-3 fatty acid supplements taken orally proved no better than placebo at relieving symptoms or signs of dry eye, according to the findings of a well-controlled trial funded by the National Eye Institute (NEI), part of the National Institutes of Health. Dry eye disease occurs when the film that coats the eye no longer maintains a healthy ocular surface, which can lead to discomfort and visual impairment. The condition affects an estimated 14 percent of adults in the United States. The paper was published online April 13 in the New England Journal of Medicine.
Annual sales of fish- and animal-derived supplements amount to more than a $1-billion market in the United States, according to the Nutrition Business Journal. Many formulations are sold over-the-counter, while others require a prescription or are available for purchase from a health care provider.
“The trial provides the most reliable and generalizable evidence thus far on omega-3 supplementation for dry eye disease,” said Maryann Redford, D.D.S., M.P.H., program officer for clinical research at NEI. Despite insufficient evidence establishing the effectiveness of omega-3s, clinicians and their patients have been inclined to try the supplements for a variety of conditions with inflammatory components, including dry eye. “This well-controlled investigation conducted by the independently-led Dry Eye Assessment and Management (DREAM) Research Group shows that omega-3 supplements are no better than placebo for typical patients who suffer from dry eye.”
The 27-center trial enrolled 535 participants with at least a six-month history of moderate to severe dry eye. Among them, 349 people were randomly assigned to receive 3 grams daily of fish-derived omega-3 fatty acids in five capsules. Each daily dose contained 2000 mg eicosapentaenoic acid (EPA) and 1000 mg docosahexaenoic acid (DHA). This dose of omega-3 is the highest ever tested for treating dry eye disease. The 186 people randomly assigned to the placebo group received 5 grams daily of olive oil (about 1 teaspoon) in identical capsules. Study participants and the researchers did not know their group assignment.
Blood tests at 12 months confirmed that 85 percent of people in the omega-3 group were still compliant with the therapy. In the omega-3 group, mean EPA levels quadrupled versus no change in the placebo group. Mean levels of oleic acid, the constituent of olive oil, remained stable in both treatment groups.
Importantly, unlike in most industry-sponsored trials, all participants were free to continue taking their previous medications for dry eye, such as artificial tears and prescription anti-inflammatory eye drops.
“Omega-3s are generally used as an add-on therapy. The study results are in the context of this real-world experience of treating symptomatic dry eye patients who request additional treatment,” said study chair for the trial, Penny A. Asbell, M.D., of the Department of Ophthalmology at the Icahn School of Medicine at Mount Sinai in New York City.
Patient-reported symptoms were measured as change from baseline in the Ocular Surface Disease Index, a 100-point scale for assessing dry eye symptoms, with higher values representing greater severity. After 12 months, mean symptoms scores for people in both groups had improved substantially, but there was no significant difference in the degree of symptom improvement between the groups. Symptom scores improved by a mean of 13.9 points in the omega-3 group and 12.5 points in the placebo group. A reduction of at least 10 points on the index is considered significant enough for a person to notice improvement. Overall, 61 percent of people in the omega-3 group and 54 percent of those in the control group achieved at least a 10-point improvement in their symptom score, but the difference between the groups was not statistically significant.
Likewise, there were no significant differences between the groups in terms of improvement in signs of dry eye. Signs of dry eye were evaluated by the clinician using standardized tests that measure the amount and quality of tears and the integrity of the cornea and the conjunctiva, the surface tissue that covers the front of the eye.
“The findings also emphasize the difficulty in judging whether a treatment really helps a particular dry eye patient,” said the leader of the coordinating center for the study, Maureen G. Maguire, Ph.D., of the Department of Ophthalmology at the Perelman School of Medicine at the University of Pennsylvania, Philadelphia. “More than half the people taking placebo reported substantial symptom improvement during the year-long study.”
“The results of the DREAM study do not support use of omega-3 supplements for patients with moderate to severe dry eye disease,” Dr. Asbell concluded.
The study was funded by NEI grants U10EY022879 and U10EY022881.
