- The major cause of “dry eyes” is a hormone deficiency; treatment for that deficiency eliminates dry eyes.
Even though a major cause of “dry eyes” was reported in 2002, and successful treatment of that cause was published the following year, every dry eyes sufferer with whom I’ve worked has been very surprised. Every one of them has told me that no ophthalmologist or optometrist informed them about it, instead recommending RestasisTM, a patent medicine whose original patent expired in 2014 but has since been kindly given more patents which don’t expire until August 27, 2024.[i],[ii]
Like all patent medicines foreign to human bodies (and almost always foreign to planet Earth, too), Restasis has numerous adverse effects. According to an online source,[iii] burning eyes is the most common, experienced by at least 10% of users. Between 1% and 10% develop red eyelids, excess tears, swollen eyes and/or eyelids, blurry vision, eye irritation, and eye pain. “Only” 0.1% to 1% develop bacterial irritation, herpes zoster (“shingles” in the eye), other eye infections, a “feeling of something in the eye,” malfunction of the cornea of the eye, corneal scarring, itchy eyelids, stinging eyes discharge, eye itching, inflammation of the iris of the eye, and inflammation—like a pimple—on the margin of the eyelid.
While it’s true that except for “burning eyes,” all of these adverse effects occur in fewer than 10% of users, the natural remedy for dry eyes has none of these adverse effects at all. This natural remedy actually is beneficial for our entire bodies, not just the eyes!
Before we go to this natural remedy, let’s look at what Restasis really is. It’s a “put-it-in-your-eye” version of a formerly patented medicine called cyclosporine (also spelled ciclosporin), which suppresses the immune system! No kidding! Cyclosporine is used in organ transplantation to prevent rejection by the immune system. Cyclosporine reduces the activity of the immune system by interfering with the growth and exposure of T cells.[iv] Why would anyone want to put an immunosuppressive patent medicine into their eyes?
On to the safe, usually effective natural remedy for dry eyes—the remedy that actually treats the cause of this problem: it’s testosterone. As simple as that! Is it any wonder that the majority of dry eye sufferers are older women, who are most likely to have low testosterone levels?
As noted above, this cause of dry eyes was found and originally published in 2002[v] by a research group led by Dr. D. A. Sullivan at the Schepens Eye Research Institute in Boston. Here are two quotes from their research report.
The first quote:
We have recently discovered that women with primary and secondary Sjögren’s syndrome are androgen-deficient. We hypothesize that this hormone insufficiency contributes to the meibomian gland dysfunction, tear film instability, and evaporative dry eye that are characteristic of this autoimmune disorder. If our hypothesis is correct, we predict: (1) that androgens regulate meibomian gland function, control the quality and/or quantity of lipids produced by this tissue, and promote the formation of the tear film’s lipid layer; and (2) that androgen deficiency, due to an attenuation in androgen synthesis (e.g., during Sjögren’s syndrome, menopause, aging, complete androgen-insensitivity syndrome [CAIS] and anti-androgen use), will lead to meibomian gland dysfunction and evaporative dry eye.
In simpler English, this quote tells us that meibomian glands in the eyelids produce oils that prevent tears from evaporating from our eyes. Meibomian glands are stimulated by androgens in both sexes; if androgens—particularly testosterone—are low, then the meibomian glands don’t make those oils, our tears evaporate . . . and we get “dry eye”!
And the second quote:
Our findings show that the meibomian gland is an androgen target organ and that androgen deficiency may promote meibomian gland dysfunction and evaporative dry eye. Overall, these results support our hypothesis that androgen deficiency may be an important etiologic factor in the pathogenesis of evaporative dry eye in women with Sjögren’s syndrome.
In brief English: androgen deficiency probably is a major cause of dry eye! Yes, these researchers limited their prediction to women with Sjögren’s syndrome, but it also applies to anyone else with meibomian glands, low testosterone, and dry eyes.
Didn’t take long (2003) for other researchers[vi] to test this prediction! A briefer quote:
Transdermal delivery of testosterone appears to be a safe and effective treatment for dry eye. The transdermal cream allows use of increased testosterone concentration and dramatically improves patient comfort. Post-menopausal females perceived the greatest relief of symptoms from the treatment, while males had the least benefit.
I’m not an ophthalmologist, so individuals with dry eyes don’t usually visit me specifically about that problem. However, over the years it’s been part of the overall health picture for many of those who visit for other reasons. Everyone with this problem—mostly women, as the research reports suggest would be the case—is checked for testosterone levels, and so far, all the women and some of the men tested have tested low or low-normal.
So far, every one of the women (but only about half of the men) have eliminated their dry eyes with testosterone use, and at the same time as a whole-body-effective hormone testosterone has improved muscle strength, lessened anxiety (yes, testosterone and other androgens significantly improve anxiety for women who test low) and in some cases improved libido, and improved auto-immune symptoms for women who have them!
One other detail about testosterone (and other bioidentical “steroid”) use: I always recommend transmucosal (rubbed-in) use because it keeps absorbing well indefinitely, while transdermal absorption frequently “fades away.” However, to relieve those dry eyes as rapidly as possible, women can safely use a tiny dab of testosterone on each eyelid in addition to what’s being used transmucosally. When the dry eyes are gone, the prescribed amount used transmucosally will maintain the eyes without any dryness!
So why haven’t many dry eye sufferers read, heard, or seen any advertisements about testosterone and dry eyes? It’s that word “patent,” which enables financing of the $2.5 billion dollar cost[vii] required to obtain approval by los federales at the FDA. With patent protection, sales of Restasis can stay at high levels ($3.26 billion in 2014),[viii] paying both this cost making a large profit, too.
Most natural treatments are unpatentable, and very often suppressed. Remember those warning letters sent from los federales at the FDA to the California walnut growers and the Michigan tart cherry growers? The FDA threatened confiscation and legal action if the walnut and cherry growers continued to publish scientifically proven truth about the health benefits of walnuts and tart cherries?
For obvious reasons, testosterone use is not likely to be suppressed, so if you have dry eyes, wouldn’t you rather give it a try for your eyes (and the rest of your body, too) instead of continuing to put an immune-system-suppressing molecule into your eyes every day?
