Three applications, 10 minutes apart, per visit are recommended; treatment is completed with compounded 20% tea tree ointment. If the patient is unresponsive to treatment, consider noncompliance or other underlying etiologies. conjunctivitis, keratitis, and other eye conditions may be associated with the presence of eyelash mites. 1963 Sep;88:298-302. Eyelash mites are known to cause a condition called Demodex blepharitis. Similarly, in cases of corneal changes, including neovascularization, infiltration, opacification, and scarring especially those non-resolving on therapy Demodex should be considered as a potential etiology.3, A definitive diagnosis of Demodex infestation is made by sampling lashes and examining samples with a confocal microscope.4 Standard sampling, defined by Coston, recommends the random epilation of four nonadjacent lashes per eyelid.27,28 It should be noted that sampling of lashes with CD is more likely to yield results, however (Figure 3).3 Lashes are then mounted to a coverslip with the addition of a droplet of oil.28 This method has been shown to underestimate the density of infestation. If recurrence of symptoms occurs during the tapering period, the patient is advised to go back to the previous treatment level and to continue at that level.

Demodex management may be dismissed by some as a mere fad in optometric practice, but with more and more patients reporting refractory dry eye symptoms, its time to consider it an actual ocular concern that can impact any patient, especially those older than 50.1 Demodex is typically not difficult to manage, but its treatment in optometric offices remains uncommon. The mechanisms of each species of Demodex are discussed below. Wash all sheets, pillow cases, and towels in hot water and dry with the high dryer setting. The Demodex mite of phylum Arthropoda comes in two forms, Demodex folliculorum and Demodex brevis.1,2 Ocular Demodex is a common, but clinically underdiagnosed condition. 1 For decades, eye care professionals have been aware of the problems caused by Demodex blepharitis. 143(5):743-749. They are instructed to cleanse the lids and lashes, as well as smear the lid cleanser onto the eyelash roots of both the upper and lower eyelid margin.4,41 Complete coverage of the eyelash base by the tea tree oil lid cleanser is necessary to be effective so that mites are unable to lay eggs and hatch more Demodex mites.41 Patients should be instructed to use the wipes on their eyelashes, forehead, eyebrows, and cheeks as the mites live in all of those areas.32,39, There are many commercially available products that contain tea tree oil. The primary cause of this condition in humans is two types of Demodex mites: Demodex folliculorum and Demodex brevis. Trans Am Ophthalmol Soc. National Library of Medicine Med Sci Monit. For more stubborn cases, Cliradex Complete (Bio-Tissue) offers a higher concentration (50% T4O) solution for in-office use two to three times in 10-minute intervals. Numerous studies, including one meta-analysis, have found a strong correlation between bacterial blepharitis and Demodex blepharitis.12-14 Demodex mites act as vectors, carrying bacteria such as Staphylococci and Streptococci as they travel between lashes.6,7,10 The superantigens produced by these bacteria are implicated in anterior blepharitis and the induction of stubborn skin conditions such as rosacea, pityriasis folliculorum, pustular folliculitis, perioral granulomatous dermatitis and permanently hyperpigmented patches on the skin.1,4-6,10, Demodex has been implicated as a causative agent in rosacea since 1932.6 The affliction affects about 16 million Americans, mostly those older than age 30 who have fair skin.15 Those affected present with erythema, flushing and transient papules along the cheeks, chin, nose and central forehead.15,21 Considered an inflammatory condition, patients suffering from rosacea have increased levels of interleukin-1a and -1b, as well as a greater activity of metalloproteinases (MMP-9 and MMP-8) in the tear film.15 These markers support the benefits of doxycycline, which acts to decrease both MMP-8 and MMP-9 expression.15, There is a large discrepancy (6% to 72%) in the prevalence of ocular involvement in those with rosacea.15,21 Investigators have found Demodex presence in 60% of patients clinically and up to 80% when detected via skin biopsy.21 Since not all rosacea patients presented with Demodex infestation, researchers believe these mites are aggravators or symptomatic, but not the causative agent.

[16] However, no comparison was done with placebo. Tea tree oil, specifically the active ingredient terpinen-4-ol (T4O), was found to be the most effective in both cleaning cylindrical debris from the roots of lashes and stimulating the migration of hidden mites to the surface for eradication.4,20 The current option with the highest concentration of terpinen-4-ol is Cliradex (Bio-Tissue).4,20 In mild cases, at-home treatments such as Cliradex, SteriLid (TheraTears), Blephadex (Lunovus) and Ocusoft scrubs BID are sufficient to decrease the Demodex population.

The majority of Demodex patients have mild to moderate symptoms that include itching and burning of the eyes and lids, foreign body sensation and fluctuating blurry vision. The Demodex duo can have multiple impacts on the anterior ocular surface, including anterior blepharitis, posterior blepharitis and meibomian gland dysfunction (MGD), ocular rosacea, and keratitis. Failure to diagnose Demodex as the underlying cause of patients signs and symptoms may result in noneffective treatment, which can result in frustration for both the clinician and patient. This article summarizes elements of pathogenesis, diagnosis, and management critical to clinical care of this common condition. Tea tree oil treatment Dr. Safran said Dr. Tseng's identification of tea tree oil to treat the Demodex is novel, and he has slightly modified the formulation. 14. Am J Ophthalmol. [QxMD MEDLINE Link]. As CD indicates higher detection of mites, Demodex counts may vary based on the presence of CD at the base of the epilated lash.5. Please confirm that you would like to log out of Medscape. As symptoms are similar to ocular surface disease, it is easy to assume dry eye syndrome and prescribe over-the-counter artificial tears rather than evaluate for the contributing factor, Demodex.

In fact, one study found that Demodex can be left in the follicle even upon epilation of lashes, which would greatly underestimate the true severity of parasitic infestation under microscopic observation.8, Still, a strong indicator of Demodex infestation is past unresponsiveness to conventional dry eye treatment. the contents by NLM or the National Institutes of Health. 2007;31(4):296-7. This helps to ensure the health of the meibomian glands, and decrease irritation and inflammation, thus keeping the eyes and eyelids healthier and more comfortable. Pilocarpine gel reduced the number of mites and alleviated the symptom of itching in 11 patients in a nursing home. Studies have shown a reduction in the number of Demodex mites with management of hypochlorous acid.39,41. In addition to dry eye symptoms, Demodex patients often complain of irritation along the lid margin. Most of the time, these mites are harmless and will go unnoticed. Though the focus of optometrists is primarily on the health of the eyes and adnexa, it is becoming more evident that we should also be prudent in taking a step back to observe and learn more about the patients overall condition to collect all pertinent information for proper diagnosis and treatment. As alarming as this may sound, they're generally harmless. Before treatment with terpinon-4-ol (Cliradex, a natural tea tree oil product), 50% tea tree oil with Macadamia nut oil was the most popular treatment method.

One of the primary goals in treating Demodex is to reduce parasitic overpopulation in the lids and lashes to decrease inflammation, providing a healthier environment for the ocular surface. Demodex folliculorum is a type of demodex mite that lives mostly within the hair follicles on the face and the eyes and is usually found on the eyelids and lashes. Demodex in small numbers don't necessarily need to be treated, but when they are present in large numbers (an overpopulation or an infestation) they can cause significant, irreparable damage to your eyelashes, eyelids, and the glands in your eyelids known as Meibomian glands. Wollina U. In severe cases, patients may even need to consider replacing their pillows altogether. Koo H, Kim TH, Kim KW, Wee SW, Chun YS, Kim JC. By understanding the natural life cycle of the Demodex mites, treatments aimed at eradicating the infestation will be more efficient. Cheng AM, Sheha H, Tseng SC.

Recent advances on ocular Demodex infestation. There are various causes of blepharitis, one of which is eyelash mite infestation. Ophthalmic ointments, such as erythromycin or Tobradex (tobramycin-dexamethasone, Alcon), along the lid margin, therefore, have been used as a solution to keep Demodex from reaching the surface to reproduce or migrate at night. [QxMD MEDLINE Link]. Demodex mites: facts and controversies. Prevalence of Demodex spp. As most dry eye cases are typically due to meibomian gland dysfunction (MGD), careful observation of the eyelid and tear film under slit lamp examination are the key to differentiating between Demodex and decreased meibum secretion. Inpatient and outpatient medications include the following: Luo X, Li J, Chen C, Tseng S, Liang L. Ocular Demodicosis as a Potential Cause of Ocular Surface Inflammation. It allows for a noninvasive magnified view of the affected follicles.7 With CLSM, mites appear round or cone-shaped; however, the two species of Demodex cannot be differentiated with this method.4 This method has been found to be a superior diagnostic tool compared to standard eyelash sampling with microscope viewing.29 CLSM can not only provide insightful information regarding MGD and conjunctival involvement but also assist in monitoring the condition for improvement.30 Unfortunately, patient cooperation is key with either method, and especially challenging in pediatric populations.3. Other related eyelid conditions are discussed separately, as is dry eye disease, which is a frequent complication of blepharitis. What's more, Demodex mites carry bacteria and release it into the skin, triggering irritation and inflammation on the lids that can lead to the signature symptoms: crusty lashes, itchiness in the surrounding skin, fluctuating blurry vision, and red, swollen, watery eyes. However, larger numbers of D. folliculorum mites can. 2005 Nov. 89(11):1468-73. [Full Text].

Because these ectoparasites are susceptible to desiccation, they require a host to survive.6 In addition, the mite population increases with age.1,3,4,6,7,9 An overpopulation of mites can lead to an imbalance of tear cytokine levels, particularly an influx of interleukin 17, which is proinflammatory, leading to blepharitis.8,10 A recent study found that 84% of those older than age 60 have Demodex, and 100% of those older than 70 are infested.4 Several studies found that the average healthy patient will likely have a small population of Demodex, but also confirmed a marked increase (two to six mites infesting each follicle) in mite population in patients older than 50.6 One study found an average count of 12.9 mites per patient seen with cylindrical dandruff, whereas those without had an average of 0.35 mitesthats a considerable difference.7 Individuals with compromised immune systems, such as those with poor systemic health and those taking immunosuppressive agents, have a higher level of Demodex, although contradicting research postulates that mites may thrive better in healthy, normal tears as opposed to tear deficient states.3. Transl Vis Sci Technol. Leibowitz HM, Capino D. Treatment of chronic blepharitis. Parasitology. D. brevis has been linked to symptomatic MGD, in part due to its predisposition toward the meibomian gland where it causes a primary mechanical blockage of the orifice.8 Accordingly, severity of MGD has been found to correlate with demodicosis by D. brevis and not by D. folliculorum.12 Accumulation of parasite excreta further contributes to this blockage and may also elicit a cell-mediated reaction.2 This blockage leads to filling, swelling, and enlargement of the gland. patients have mild to moderate symptoms that include itching and burning of the eyes and lids, foreign body sensation and fluctuating blurry vision.

While therapy for traditional blepharitis includes warm compresses and antibiotic/steroid combinations, these therapies do not eradicate Demodex, often causing the condition to persist.31 If left untreated or when poorly managed adverse effects such as redness, inflammation, telangiectasia, MGD, and ocular allergy may persist. 26 (4):295-300. Signs of Demodex infestation include collarettes and crusting or matting of eyelashes, tearing, and blurry vision. 2014 May 12;10(2):319-24. Demodex is a genus of microscopic mites that live in human hair follicles. Demodicosis is diagnosed when there is a high density of demodex mites (> 5/cm 2). [QxMD MEDLINE Link].
