Ethnic characteristics of eyelashes: a comparative analysis in Asian and Caucasian females.

BACKGROUND: Despite similar biochemical composition of human hair between races, physico-morphological characteristics are not identical in different ethnic groups. Eyelashes have been investigated far less than scalp hair, and the information available is insufficient. OBJECTIVES: To obtain basic information about eyelashes and to clarify differences between female eyelashes in Asians and Caucasians. METHODS: Twenty Asian and 10 white Caucasian female volunteers aged between 20 and 29 years were admitted to the study. Lateral digital photographs of upper eyelashes were taken and curl-up and lift-up angles of upper eyelashes were measured from lateral views. Images of upper eyelashes were also taken using the phototrichogram technique and total numbers, lengths and thicknesses of upper eyelashes were obtained (a total of 4661 eyelashes; 2946 for Asian, 1715 for Caucasian). The central portion of the eyelashes or whole eyelashes were clipped and images were taken immediately and 7 days later to obtain the growth rate and anagen ratio of upper eyelashes. Numbers and thickness of eyelash cuticular layers were obtained by electron microscopy. RESULTS: Compared with Caucasians, Asian eyelashes revealed lower lift-up and curl-up angles, fewer numbers and a thicker transverse diameter. However, no statistical difference was observed in length or growth rate. Duration of anagen was estimated at about 2 months. The eyelash anagen ratio obtained from five Asians was 17.8 +/- 3.3%. By electron microscopy, the number of cuticular layers in transverse section was greater in Asian (8.0 +/- 1.2) than Caucasian females (6.5 +/- 1.1), but no statistical difference was found in single cuticle layer thickness between the two groups. Moreover, eyelash characteristics were not influenced by eye makeup in either race. CONCLUSIONS: Our results on eyelash morphology and growth characteristics demonstrated significant ethnic differences in Asian and Caucasian females that could provide basic information for future investigations.

The character of eyelashes and the choice of mascara in Korean women.

BACKGROUND/AIMS: Skin care products based on the skin type and sensitivity have been successfully appealed in cosmetics market, but there has been few researches related with the character of customer in the field of make-up product including mascara. The aim of this study is to analyse and classify the eyelashes of Korean women objectively and to find out the relationship between individual eyelash character and expecting mascara-effect. METHODS: For 50 Korean women in their twenties to thirties, 12 parameters related to shape of eyelashes were investigated using image analysis system with digital camera. The experimental data were compared with the subjects' perception and questionnaire to determine the tendency of mascara was performed on same panels. Subjects were classified and the relation between the shape of eyelashes and need for mascara was investigated by statistical procedure. RESULTS: Average length of centre section (ALCS), covering ratio (CR) and curl-up angle (CA) were the numerical parameters that can represent the length, thickness and curling of subjects' eyelashes, respectively. Subjects were classified into 6 clusters (I approximately VI) by the similarity of above three parameters using cluster analysis method. Cluster I approximately III were characterized as the short and thin eyelashes with a preference for long-lash effect and complaint about staining of lower-eyelid in the use of mascara. Cluster IV approximately VI had the long and thick eyelashes with preference for volume-up effect of mascara and complaint about cleaving of eyelashes. Subjects had five sorts of preference patterns about mascara-effects and those patterns were highly related with the shape of their eyelashes. CONCLUSION: Image analysis system and statistical procedure were the useful methods in characterizing the shape of eyelash and finding the objective criteria for classification of eyelashes. Because shape of eyelash turned out to be one of the most important factors that can influence the need and complaint of subjects about mascara in this study, the consideration of shape of eyelashes is recommended in the development of mascara which can satisfy the customers' demand.

Low incidence of iris pigmentation and eyelash changes in 2 randomized clinical trials with unoprostone isopropyl 0.15%.

OBJECTIVE: To assess whether iris color and eyelash changes occur with the use of unoprostone for 2 years. DESIGN: The 2 clinical trials described herein were prospective, randomized, double-masked, active-controlled, parallel group, multicenter studies. PARTICIPANTS: A total of 1131 patients with primary open-angle glaucoma or ocular hypertension participated in 2 clinical trials and received either unoprostone isopropyl 0.15% (659), timolol maleate 0.5% (331), or betaxolol hydrochloride 0.5% (141), 1 drop per eye twice daily for up to 24 months. METHODS: Color photographs (1:1 magnification) were taken of the iris and eyelid of each patient at baseline and at regular intervals thereafter through month 24 using a standardized camera system. Photography included 7 views of each eye plus a calibration photograph and a patient identification photograph, for a total of 16 photographs per patient per visit. Two independent (masked) readers subjectively compared baseline iris colors to subsequent visits. Side view photographs of the upper and lower eyelashes were used for the eyelash length analysis, with each having sufficient depth of field and a sufficient number of eyelashes in focus. Similarly, frontal eyelash views were used for the eyelash density analysis. MAIN OUTCOME MEASURES: Changes from baseline in iris color and eyelash length and density within and between treatment groups. RESULTS: Seven cases of iris color change (1.06%) were confirmed in patients treated with unoprostone for up to 24 months; no confirmed cases were reported in the timolol or betaxolol groups. In the unoprostone group, cases of iris color change were confirmed at months 12 (1 case), 18 (2 cases), and 24 (4 cases). No clinically relevant differences were observed among treatment groups for changes from baseline in eyelash length or density. CONCLUSION: Although iris hyperpigmentation and abnormal eyelash changes may occur after treatment with unoprostone, the incidence of these events appears to be low in the 2-year clinical study.

Scorched eyelashes--do we treat them right?

Scorched eyelashes and burned eyelids are a common finding in facial burns, though the eye itself is often spared. Affected patients often complain of foreign body sensation and ocular discomfort in the absence of objective physical findings, other than scorched eyelashes and burned eyelash particles in the conjunctival sacs. This study was designed to evaluate the efficacy of prophylactic trimming of scorched eyelashes as a treatment for these findings and complaints. Eleven consecutive facial burn patients with bilateral eyelash scorching and no accompanying ocular damage were included. The eyelashes of one eye were trimmed, and those of the fellow eye served as untreated controls. Ophthalmic examinations were performed and eye-related complaints noted every other day for 10 days. We found that symptoms of foreign body sensation and discomfort occurred at a lower rate in the treated eyes (P<0.002) and no scorched eyelash particles were found in their conjunctival sacs (P<0.004) as compared to the untrimmed side. Conjunctival hyperemia was reduced. We suggest that shedding of scorched eyelash particles is a major cause of the ocular complaints in facial burn patients. Trimming the eyelash affords a simple and effective method of prophylactic treatment.

Long eyelashes in a case series of 93 children with vernal keratoconjunctivitis.

OBJECTIVE: Vernal keratoconjunctivitis (VKC) is a chronic conjunctivitis that affects children mainly in temperate areas, with exacerbations in spring and summer. Eyelashes provide natural protection for the eyes from sunshine, wind, and foreign bodies. These factors induce a worsening of signs and symptoms in VKC, whereas mechanical protection of the eyes produces relief. The aim of this study was to evaluate eyelash length in a large series of VKC patients and in age- and gender-matched healthy subjects. METHODS: Upper eyelash length was measured in 93 VKC patients (mean age: 8.7 years; range: 4-18 years) with a digital caliper. History, clinical form, type of presentation, degree of severity, and drug therapy were evaluated. Skin tests and serum-specific immunoglobulin E for common allergens, serum-total immunoglobulin E, peripheral blood eosinophil counts, and serum eosinophil cationic protein were determined. Two age- and gender-matched control subjects for each VKC patient underwent the same eyelash measurement. RESULTS: The upper eyelashes were significantly longer in VKC patients than in control subjects (mean +/- SD: 8.9 +/- 1.17 mm vs 7.9 +/- 1.07 mm). In healthy subjects, a negative correlation was found between eyelash length and age. With multivariate analysis, unlike control subjects, the eyelash length in VKC patients did not correlate with age, was positively correlated with the degree of severity of VKC, and was negatively correlated with the use of topical cyclosporine. CONCLUSIONS: Patients with VKC had longer eyelashes than healthy matched subjects. The ocular inflammation, by unknown chemical mediators, was likely responsible for the excessive eyelash growth. The finding may represent a defensive mechanism against physical agents that might have a crucial role in the etiopathogenesis of this disease.

Eyelash length in children and adolescents with allergic diseases.

Long eyelashes may be congenital, acquired in association with certain systemic diseases, or drug induced. In the past, long eyelashes were considered an external sign found in children with allergic diseases. However, this claim has never been examined in a controlled study. We compared the eyelash lengths of allergic children and adolescents with perennial allergic rhinitis, with or without bronchial asthma and atopic dermatitis (n = 60) to those of age- and sex-matched nonallergic controls (n = 80). The eyelashes of the allergic patients were found to be significantly longer than those of the controls: 9.43 +/- 1.39 mm versus 8.45 +/- 1.30 mm (p < 0.001). Eyelash length did not differ between patients with allergic rhinitis only (n = 31; 9.65 +/- 1.43 mm) and patients with allergic rhinitis and other allergic diseases (n = 29; 9.19 +/- 1.31 mm) (p = 0.196). These results indicate that children and adolescents with allergic diseases have longer eyelashes compared to nonatopic controls and that long eyelashes may be a part of the phenotype of the allergic patient.

The role of eyelash dyes in allergic eye diseases.

A case-control study was carried out on 544 patients who attended our out-patient eye clinic from 1998 to 2002 to determine the role of eyelash dye in allergic eye diseases. There were 272 cases who had allergic eye disease and 272 controls who were patients with no allergic eye disease. The results showed that 51.8% of all patients used eyelash dyes, 70.8% of whom used homemade dyes. Atotal of 82.6% of patients reported the worsening of the eye condition after starting the use of eyelash dyes. Of the 272 cases, 63.2% used eyelash dyes; in the control group, 40.4% used eyelash dyes. This was a statistically significant difference. It was concluded that eyelash dyes can be one of the major precipitating/aggravating factors in allergic eye diseases.

The comparison of eyelash lengthening effect of latanoprost therapy in adults and children.

PURPOSE: To compare the eyelash lengthening effect of latanoprost in adults and children with glaucoma. METHODS: Twenty eyes of 13 men and 7 women (mean age: 54.9, range 42-69 years) with primary open-angle glaucoma and 20 eyes of 9 boys and 11 girls (mean age: 10.7, range 6-16 years) with glaucoma were included in this prospective study. In 19 children, juvenile glaucoma and in one, pseudophakic glaucoma had been detected. A single eyelash was pulled from the center of the upper eyelid before latanoprost therapy and at the sixth month of therapy, and measured. RESULTS: In adult cases, the mean eyelash length was 5.79+/-0.18 mm (5.5-6.1 mm) at baseline and 6.45+/-0.21 mm (6.2-6.8 mm) at the sixth month. In children, the mean length was 5.66+/-0.22 mm (5.3-6.0 mm) at baseline and 6.39+/-0.37 mm (5.9-6.9 mm) at the sixth month. The mean difference in eyelash lengths at baseline and the sixth month was 0.67+/-0.09 mm (0.5-0.7 mm) in adults and 0.75+/-0.25 mm (0.4-1.2 mm) in children. CONCLUSIONS: The differences in mean eyelash lengths at baseline and at the sixth month of latanoprost therapy were statistically significant in both adults and children (p=0.000). The mean of the difference of the eyelash length in children was higher than in adults but the result was not statistically significant (p=0.678).

A prospective study of iridial pigmentation and eyelash changes due to ophthalmic treatment with latanoprost.

PURPOSE: To conduct a 12-month prospective study on the occurrence of latanoprost-induced iridial pigmentation and eyelash change in Japanese patients with glaucoma METHODS: Seventy-five patients (75 eyes) were enrolled in the study. Photographs of the iris and eyelashes were taken under identical conditions before and after treatment. Three glaucoma specialists assessed the iridial pigmentation/eyelash change independently with no knowledge of patient data. The effects of age, sex, concomitant medication, and type of glaucoma on iridial pigmentation/eyelash change were investigated, and intraocular pressure (IOP) reduction and iridocorneal angle pigmentation before and after latanoprost treatment were compared between patients with iridial pigmentation/eyelash change and patients without these changes. RESULTS: The incidence of iridial pigmentation was 6.3% at 1 month, 15.7% at 3 months, 37.8% at 6 months, and 56.5% at 12 months. The incidence of eyelash change was 0% at 1 month, 33.8% at 3 months, 44.4% at 6 months, and 46.2% at 12 months. Latanoprost did not affect IOP reduction or iridocorneal angle pigmentation. No significant relationship between iridial pigmentation and eyelash change was observed. None of the investigated parameters except age affected the iridial pigmentation/eyelash change. CONCLUSION: Iridial pigmentation and eyelash change occurred at a high frequency in long-term treatment with latanoprost in Japanese glaucoma patients.

Quantitative analysis of eyelash lengthening following topical latanoprost therapy.

BACKGROUND: There have been several reports, mostly qualitative, of ocular side effects of latanoprost, including lengthening of eyelashes. We investigated changes in eyelash length in patients receiving topically administered latanoprost. METHODS: Seventeen patients (11 men and 6 women aged 63 to 80 years) with glaucoma or ocular hypertension were treated with latanoprost (one drop to one eye daily at bedtime). All had dark brown irises. At the start of treatment and after 2, 6 and 10 weeks of treatment, a single eyelash was removed from the centre of the upper eyelid of the treated and fellow (control) eyes and measured. Adverse events (defined as any undesirable event occurring in a subject, regardless of whether it was considered related to the latanoprost treatment) were monitored carefully. At each examination patients were asked whether they had any ocular or systemic symptoms. RESULTS: For the eyes treated with latanoprost, the mean eyelash length (and standard deviation) was 5.8 mm (0.7 mm) at baseline, 6.5 mm (0.6 mm) at 2 weeks, 6.5 mm (0.9 mm) at 6 weeks and 6.6 mm (0.7 mm) at 10 weeks (p < 0.001 for all differences from baseline). The corresponding values for the untreated eyes were 5.7 mm (0.7 mm), 5.8 mm (0.7 mm), 5.9 mm (0.7 mm) and 5.6 mm (0.7 mm); all differences were nonsignificant. INTERPRETATION: Latanoprost significantly increases eyelash length.

Contact allergy to para-phenylenediamine in a permanent eyelash dye.

We present the case of a 30-year-old atopic lady with a known history of intolerance to several materials, including dark stockings, who developed a severe dermatitis on the eyelids and peri-orbital regions, as well as a conjunctivitis after having her eyelashes tinted by a beautician with a permanent black eyelash and eyebrow dye (Combinal, Dr Temt Laboratories, Austria). Patch tests revealed positive reactions to para-phenylenediamine (PPD), both diluted 0.01% and 1% in pet., to the eyelash dye (tested semiopen as is) and to some of the azo-dyes tested. The permanent eyelash dye did contain PPD, the use of which is illegal but seems to be a common practice. The patient had most probably been sensitized through nylon stockings containing azo-dyes, with PPD itself cross-reacting to them. With the growth in popularity of tattooing and permanent make-up, doctors should be aware of the new uses of this old allergen. Moreover, although many manufacturers have made great efforts to improve cosmetics concerning their safety, some of them remain uninformed about cosmetic legislation or do not respect it at all. Because many of these products are acquired via internet, lack of legislation about this shopping modality is also a serious problem.

Isolated eyebrow and eyelash trichotillomania mimicking alopecia areata.

BACKGROUND: Isolated Trichotillomania (TM) of the eyebrows and eyelashes is occasionally seen and may be mistaken for alopecia areata (AA). OBJECTIVE: The clinical study of the patients with isolated eyebrows and eyelashes alopecia suggesting of TM. PATIENTS AND METHOD: Seven children and young adult patients who referred with recalcitrant eyebrows and eyelashes alopecia were diagnosed as TM based on the clinical criteria for TM. The hair specifications for TM were include: hairs are broken at different levels, they may be tufted, tortuous and some hair fibers may be abnormally longer than others. The hair follicles may be prominent. The patients and their parents studied for psychopathology using a semistructured interview based on the Diagnostic Statistical manual of Psychiatric disorders (DSM-1V) and maudsley inventory. RESULTS: Our clinical study, interview with the patients and their parents and the clinical criteria used to differentiate TM from AA all support the clinical diagnosis of TM. The patients and their parents mainly suffered from obsessive-compulsive disorders (OCD) and obsessive-compulsive spectrum disorders (OCSDs). CONCLUSION: TM as a hair pulling habit in patients with underlying psychopathology can be considered in cases with isolated eyebrows and eyelashes alopecia when the hair are broken at different levels. And they may be malaligned, nonuniform, tortuous, and tufted.

Distichiasis and dysplastic eyelashes in trachomatous trichiasis cases in Oman: a case series.

The study was a prospective evaluation of the prevalence of distichiasis and/or dysplastic eyelashes among trachomatous trichiasis cases at the oculoplasty unit of a hospital in Oman over 3 months in 2000. An oculoplasty surgeon examined and photographed cases using a bio-microscope. Out of 80 cases, 58 (72.5%) had abnormal eyelashes in addition to trachomatous trichiasis. The rate of distichiasis and dysplastic lashes were 13.8% (95% CI 6.2%-21.3%) and 33.8% (95% CI 23.5%-44.1%) respectively; 25.0% (95% CI 15.5%-34.5%) had both. Dysplastic and distichiasis eyelashes were significantly more prevalent in trachomatous trichiasis cases aged < 50 years and those with entropion. Presence of distichiasis and/or dysplastic eyelashes in trachomatous trichiasis cases warrants further analytical studies to confirm the observation and establish any causal association.

Hypertrichosis of the eyelashes caused by bimatoprost.

The phenyl-substituted analog of prostaglandin F 2alpha , latanoprost (Xalatan; Pfizer, Inc, New York, NY) is an intraocular pressure (IOP)-lowering drug for use in patients with glaucoma and ocular hypertension. Latanoprost has been shown to stimulate eyelash hypertrichosis and has recently been proposed as a possible treatment for alopecia areata involving the eyelashes. We report a case of hypertrichosis of the eyelashes caused by the prostamide bimatoprost (Lumigan; Allergan, Inc, Irvine, Calif), a new IOP-lowering drug.

Hypertrichosis and increased pigmentation of eyelashes and adjacent hair in the region of the ipsilateral eyelids of patients treated with unilateral topical latanoprost.

PURPOSE: To describe hypertrichosis and increased pigmentation of eyelashes associated with topical latanoprost usage. METHODS: Patients using unilateral topical latanoprost for glaucoma were examined for evidence of hypertrichosis and pigmentation of eyelashes and adjacent hair in the latanoprost-treated eye compared with the nontreated control eye. RESULTS: In 43 patients receiving unilateral topical latanoprost, hypertrichosis involved ipsilateral terminal eyelashes and regional intermediate hairs of the upper and lower eyelid as well as vellus hair of the lower eyelid skin. Differences in hair appearance between the latanoprost-treated eye and the nontreated control eye included increased number, length, thickness, curvature, and pigmentation. CONCLUSIONS: Latanoprost-treated eyes develop hypertrichosis and increased pigmentation in the region of treatment. Patients may benefit from being made aware of this side effect.

Severe allergic blepharoconjunctivitis induced by a dye for eyelashes and eyebrows.

PURPOSE: To report a case of severe allergic blepharoconjunctivitis induced by a dye for eyebrows and eyelashes. METHODS: A 38-year-old healthy female was examined one day after dyeing her eyebrows and eyelashes with a black cream dye intended for this purpose (FDA-approved). The patient complained of severe eye itching, redness, and epiphora. RESULTS: Vision was 20/40 in both eyes; a moderate edema of the eyebrows and eyelid margins was noted. The conjunctiva was severely hyperemic with papillary reaction and chemosis. The corneas, anterior chambers, irides, lenses, and posterior segments were normal. The patient was treated with Dexamethasone 0.1% and ocular lubrication. After five days of treatment, the ocular symptoms improved, her vision returned to 20/20 in both eyes, and the ocular examination was within normal limits. CONCLUSION: FDA-approved dyes for eyebrows and eyelashes can sometimes irritate the ocular surface.

Eyelash length in HIV-infected patients.

Acquired trichomegaly of the eyelashes in HIV-infected patients usually appears at the late stage of HIV infection. Eyelash length was measured in a series of 204 HIV patients, and no correlation with CD4 cell count, viral load, Centers for Disease Control and Prevention category, and AIDS case criteria was established. Our data support the finding that eyelash trichomegaly is currently uncommon in HIV-infected patients, perhaps because of antiretroviral therapy or an improvement in their immune situation.
