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.

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.

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.

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.

Anatomy and physiology of eyelash follicles: relevance to lash ablation procedures.

BACKGROUND: This study aimed to define the anatomy of the eyelash follicles in order to improve methods of selective lash ablation. MATERIALS AND METHODS: Dimensions of eyelash follicles were determined from histological specimens of the upper and lower lids of 10 patients. For one of these patients, the eyelash follicles were categorized as quiescent or actively growing, according to standard hair-cycle morphology. RESULTS: Follicle dimensions were (mean +/- SD): upper lid follicle depth, 1.8 +/- 0.3 mm; bulb width, 188 +/- 44 microns; shaft width, 205 +/- 28 microns; lower lid follicle depth, 0.9 +/- 0.2 mm; bulb width 132 +/- 19 microns; and shaft width, 158 +/- 26 microns. The upper lid comprised 41% active follicles compared to 15% in the lower lid. CONCLUSIONS: There are significant differences in the anatomy of the follicles between the two lids. For an electrolysis needle to completely contact 95% of all follicles, it must be inserted 2.4 mm into the upper lid and 1.4 mm into the lower lid (mean depth +2 SD). Argon laser ablation requires a beam width of < 200 and < 250 microns for the lower and upper lids, respectively, to treated similar depths as electrolysis. The higher proportion of actively growing upper lid follicles explains why upper lid lashes are longer.

Complications of eyelash and eyebrow tattooing: reports of 2 cases of pigment fanning.

Eyelash and eyebrow tattooing are commonly performed procedures that have a very low rate of reported complications. We describe one case of infraorbital pigmentation after eyelash tattooing and another of periorbital pigmentation after eyebrow tattooing. Although most complications related to eyelash and eyebrow tattooing, including pigment fanning, have been reported by ophthalmologists, pigment fanning is also of concern to dermatologists.

The true rate of success in argon laser eyelash thermoablation.

Argon laser thermoablation has a success rate of 50% typically, when success is defined as an absence of recurrence of any eyelash per lid treated. When success is redefined as an absence of recurrence per eyelash treated, the success rate increases to 76% to 93%. Laser thermoablation potentially offers selective eyelash ablation with minimal inflammation and adjacent tissue damage. Its true rate of success may be better than previously indicated.

An unusual adverse effect of interferon: hypertrichosis of the eyelashes.

Hypertrichosis of the eyelashes is a rare adverse effect of interferon-alpha treatment. We present a 21-year-old man with chronic renal failure and hepatitis B virus (HBV) infection who developed hypertrichosis of the eyelashes as a complication of IFN-alpha therapy. The patient was a candidate for living related renal transplantation and was given IFN-alpha 15 million units per week for HBV DNA positivity. After 6 months of therapy, HBV DNA positivity persisted, and the dose of IFN was increased to 30 million units per week. At the end of the first half of the second 6 months of therapy, the patient suffered from bilateral hypertrichosis of the eyelashes.

Inverted eyelashes in patients with type 1a glycogen storage disease.

We examined three adult Japanese patients who had a history of decreased hepatic glucose-6-phosphatase activity. All three patients had increased bilateral subcutaneous (SC) fat in the lower eyelids and inverted eyelashes. One patient additionally showed retinal hemorrhages and microaneurysms in both fundi. The inverted eyelashes may have been related to type 1a glycogen storage disease.

An eyelash nidus for dacryoliths of the lacrimal excretory and secretory systems.

We treated two patients with dacryolithiasis secondary to an eyelash. The first patient underwent dacryocystorhinostomy for a stone within the lacrimal sac. In the second patient the dacryolith was removed from a lacrimal gland ductule. Eyelashes found in the tear film or conjunctival fornices during routine examination should be removed to prevent the possible occurrence of dacryolithiasis.

An experimental study to compare methods of eyelash ablation.

Epilation, electrolysis, cryotherapy, and argon laser thermal ablation were used to remove eyelashes of rabbits. Epilation and electrolysis were done in the standard fashion. Nitrous oxide cryotherapy was applied in a double rapid-freeze/slow-thaw manner for either 30 or 60 seconds. Argon laser settings were 1 W, 50-micron spot size, and durations of 0.2, 0.5, or 1.0 second. The rabbits were euthanized immediately, 24 hours, 2 weeks, or 3 months after the procedure. Epilation was followed by total regrowth of eyelashes within 2 weeks. Electrolysis showed focal destruction of follicles with variable regrowth. Cryotherapy resulted in moderate-to-severe eyelid scarring with minimal regrowth. Argon laser thermal ablation produced focal necrosis and variable follicle destruction. Argon laser thermal ablation may be a suitable alternative to electrolysis or cryotherapy in selected cases of trichiasis.

Dysversion of lateral eyelashes in children: a new diagnosis.

We believe that a previously undocumented cause of recurrent red, watery, sore and itchy eyes in children is dysversion of the lateral eyelashes. Diagnosis requires a close examination of the lateral aspect of the eyelids where dysverted lashes are seen to be growing from normal follicles. The lateral lashes are fine, long and flexible. They curve inwards and rub on the conjunctiva and cornea, and cause the above symptoms. Secondary signs include skin changes, recurrent conjunctivitis, and corneal abrasions. Conservative treatment consisting of manual repositioning of the dysverted eyelashes is recommended so that surgery may be avoided. Recognition of the condition by the primary practitioner, and institution of the straightforward treatment described above, can obviate much morbidity. The inappropriate use of topical antibiotics and frequent return visits to the practitioner may also be thus avoided.

Phthirus pubis infestation of the eyelashes and scalp hairs in a girl.

A 4-year-old girl was seen because of foreign bodies on the eyelashes. Parasites and their nits were seen on the patient's eyelashes and scalp. Her parents denied having Phthirus pubis infection of the axillary, pubic, or body hair, despite confirmation of the infestation in their child. The parasites were removed and the lashes with nits were cut off at the base. The parasite was identified as P. pubis. The scalp was washed with phenothrin shampoo. One month later no P. pubis infestation was found. Removal of the parasites, cutting the lashes at the base, and using phenothrin shampoo on the scalp were effective in resolving phthiriasis.

Acquired eyelash trichomegaly and alopecia areata in a human immunodeficiency virus-infected patient.

We describe a human immunodeficiency virus (HIV) seropositive man with acquired eyelash trichomegaly and alopecia areata. This combination of clinical manifestations is intriguing since the new onset of elongated eyelashes in patients with acquired immunodeficiency syndrome has usually been associated with severe immunosuppression and alopecia areata has a presumed autoimmune etiology that requires T cell activation. The occurrence of these dichotomous conditions illustrates the potential selective pathogenesis of progressive HIV infection.
