We presented the clinical features of a 9-year-old girl and a 52-year-old man with alopecia areata of eyelashes. Alopecia areata refers to the idiopathic lesions of the eyelashes and is generally classified as being partial, total or universal.
Previously described surgical techniques for distichiasis correction are likely to have complications of trichiasis, entropion, and eyelid margin distortion. A new technique to remove distichiasis eyelashes through a tarsoconjunctival trapdoor achieves a satisfactory functional and cosmetic result and descreases the likelihood of these complications.
We herein describe a patient in whom two intraocular eyelashes and an anterior chamber cyst embedded into the anterior surface of the iris was detected following penetrating eye injury. After a one year asymptomatic period, the patient was hospitalized because of uveitic reaction in the anterior chamber which may be due to cyst development. The lashes and cyst were removed surgically, and examined pathologically. There was no complication in one year follow-up period.
X-linked dominant chondrodysplasia punctata or Happle syndrome is a rare hereditary disorder. The clinical features include retardation of growth, cataract, and temporary, ichthyosiform erythroderma. Atrophic lesions and hyperkeratotic papules of the skin and disturbances of hair growth follow the lines of Blaschko. A 5-year-old girl with X-linked dominant chondrodysplasia punctata was found to be mentally retarded and to have abnormalities of the eyelashes (growth and pigmentation), which had not previously been described in this condition.
Acquired trichomegaly of the eyelashes was found in seven patients infected with human immunodeficiency virus type 1. These patients had advanced infection with severe T-helper cell depletion, high levels of p24 antigenemia, and inability to tolerate zidovudine therapy. Control of infection with other antiretroviral agents caused the trichomegaly to regress. Acquired trichomegaly may be a useful clinical marker for assessment of severity of infection.
BACKGROUND: When operating hair removal lasers on the face or in the periorbital region, even with an ocular shield in place, patients often report seeing "flashing lights" each time the laser is fired. This phenomenon suggests stimulation of retinal photoreceptors and raises laser safety issues. OBJECTIVE: To perform retinal electrophysiologic studies to evaluate the safety of hair removal lasers in the periorbital region. METHODS: Five patients with severe trichiasis secondary to trachoma were studied. The 810 nm Dioderm laser (Cynosure, Inc., Chelmsford, MA) was used to treat the eyelash follicles on the lower eyelid of each patient. Cox III metal eye shields (Oculo-Plastik, Inc., Montreal, Canada) were placed behind the eyelids of both eyes during the laser procedure. Prior to irradiation, a comprehensive ophthalmic evaluation including pupillary and slit-lamp examination, funduscopy, and full-field electroretinograms (ERGs) was performed. A comprehensive ophthalmic evaluation including ERG testing was repeated 30 minutes and 3-6 months after completion of treatment. An independent blinded assessor evaluated the ERG studies. Subjective reports of laser light sensation, pain, and discomfort during and after the laser procedure were also assessed. RESULTS: There was no detectable change in slit-lamp, pupillary, or funduscopic evaluations after periorbital laser irradiation. Similarly the pre- and posttreatment ERGs were unchanged. Three patients reported seeing flashing lights during the procedure. CONCLUSION: We found no ERG evidence of retinal damage after laser hair removal in the periorbital region, with Cox III-type ocular shields over the eyes, even when patients subjectively reported "flashing lights" during laser irradiation.
Ingrown eyelashes are an interesting finding closely related to ingrown hairs of the body. This phenomenon is fairly uncommon and is sparsely referred to in the ophthalmic literature. The condition can produce patient complaints, and therefore deserves optometric recognition.
We describe a four-generation Brazilian family with short tarsus and absence of the lower eyelashes, with normal intelligence. Autosomal dominant inheritance is evident.
Japanese dermatologists have successfully used single-hair grafts and grafts of two and three hairs for the reconstruction of eyebrows, eyelashes, pubic hair, and alopecic scars in scalps. A brief review of the Japanese literature and surgical technique is given followed by a case report of transplantation of hairs from the scalp as lashes by the author's modification of the Japanese technique.
The variety of lesions that can cause alopecia of the eyelashes (Table 1) demonstrates the need for accurate diagnosis. A full-thickness biopsy of lid margin with appropriate three-suture closure can leave an imperceptible defect and may provide invaluable information. Although a partial-thickness lid biopsy is certainly appropriate for many common eyelid tumors such as basal-cell carcinomas or nevi, we feel strongly that a full-thickness lid biopsy is indicated when discussing chronic eyelid lesions that cause alopecia. The information gathered from a full-thickness biopsy is far superior especially in those lesions which cause chronic blepharitis or especially in a case of a recurrent chalazion where the conjunctival surface and skin surface are both equally significant. The high mortality associated with sebaceous-cell carcinomas makes a good pathologic specimen allowing for accurate diagnosis essential. Partial-thickness eyelid biopsies, especially in cases of sebaceous carcinoma, may lead the pathologist to an erroneous, more benign, diagnosis and the clinician to a false sense of security. While many of the nonscarring alopecias may be diagnosed on their clinical characteristics alone, the scarring alopecias will frequently need a lid biopsy to ascertain diagnosis and gauge treatment.
A dacryolith was discovered in the lacrimal sac during a dacryocystorhinostomy for chronic dacryocystitis in which there was mucocele formation. Morphological examination confirmed the presence of an eyelash at the centre of the stone and electron microscopy demonstrated the presence of fungi (Candida sp.) in a matrix which was of markedly vairable morphology. The mechanism by which a hair enters the punctum and passes along the canaliculus may be attributed to the step-like pattern of ridges on the surface of a hair. The directional nature of these ridges dictates preferential movement towards the root end of the hair and prevents movements in the opposite direction.
Epiblepharon commonly occurs in Japanese infants and tends to disappear spontaneously with age. We examined 4449 Japanese children aged 3 months to 18 years for epiblepharon associated with inverted eyelashes touching the cornea. The condition was evident in 441 cases. We found that the incidence of epiblepharon decreased with age, but about 2% of high school students still had the condition. No sexual predilection was found. Lower eyelids were commonly involved bilaterally. Most cases of epiblepharon produced no or mild symptoms.
We used lid bracing sutures, buried sutures, and skin resection operations to correct epiblepharon in Japanese children. Epiblepharon and ocular irritation in 103 children (254 eyelids) were treated first with lid bracing sutures. Postoperatively the inversion of eyelashes resolved in 73 patients (196 eyelids). Of these 103 patients 30 (58 eyelids) developed recurrences, which included 11 who also complained of foreign body sensation and ocular pain. These 11 patients (22 eyelids) underwent a second surgical procedure (buried sutures or skin resection) before they became free of symptoms. No severe complications were noted in any of the 103 patients. We believe that lid bracing sutures correct most cases of mild epiblepharon in children and that buried sutures or skin resection are valuable for more severe conditions.
PURPOSE: To determine the prevalence of Demodex in eyelashes with cylindrical dandruff (CD). METHODS: A modified sampling and counting method was applied to 55 clinical cases. Patients were divided in to group A (n = 20) with diffuse CD, group B (n = 12) with sporadic CD, and group C (n = 23) with clean lashes or greasy scales, of which the latter was divided into subgroup C1 (n = 15) without lid hygiene and subgroup C2 (n = 8) using daily lid hygiene for the past year. Each patient underwent a routine complete eye examination and modified counts of Demodex. RESULTS: Demodex was found in all group A and B patients (n = 32) with CD, which was significantly higher than the 22% of group C patients (n = 23) without CD (P < 0.001). The Demodex counts were 4.1 +/- 1.0 and 2.0 +/- 1.2 per epilated lash with retained CD, significantly higher than the 0.2 +/- 0.5 and 0.2 +/- 0.4 per lash without retained CD in groups A and B, respectively (each P < 0.001) and than the 0.01 +/- 0.09 and 0.12 +/- 0.41 per lash in subgroups C1 and C2, respectively (each P < 0.001). Demodex was still found in CD fragments left on the lid skin after epilation. Five Demodex brevis mites were found among the 422 Demodex specimens. CONCLUSIONS: The modified sampling and counting method showed that the prior controversy regarding Demodex has resulted from miscounting and confirmed that lashes with CD are pathognomonic for ocular Demodex infestation. Lid hygiene with shampoo reduces Demodex counts but does not eradicate the mites.
We describe a female patient with a history of primary open-angle glaucoma who, following treatment with topical latanoprost, a synthetic prostaglandin F2 alpha analog, developed hypertrichosis of the eyelashes. Hypertrichosis, a recently described side effect of latanoprost--together with iridal pigmentation--represents a potentially permanent cosmetic side effect associated with the use of this highly effective intraocular pressure-lowering agent. The molecular mechanism underlying latanoprost-induced hypertrichosis is unknown.
Acquired eyelash trichomegaly is a rare condition. We present a 23-year-old woman with acquired trichomegaly and generalized hypertrichosis from childhood. The patient also exhibited bilateral nipple retraction and unilateral left-sided accessory nipple. According to our knowledge the association between trichomegaly, hypertrichosis, and breast anomaly has not been reported.
Two children with abnormally long eyelashes and bushy brows ("trichomegaly") present at birth and associated with pigmentary degeneration of the retina and general growth retardation are described. This combination of findings has been observed previously in three cases. Mental retardation, sparse scalp hair, endocrinologic deficiencies and (in one of our cases) koilonychia may be found in addition, but not necessarily.
We report a new case of excessive growth of eyelashes in a patient seropositive for human immunodeficiency virus 1. The exact mechanism of this hypertrichosis is still unknown. Although this sign seems to occur late in the human immunodeficiency virus infection, we believe early recognition of this manifestation could lead, in some cases, to earlier diagnosis of the infection.
