Eyelash Length in Children and Adolescents with Allergic Diseases

Abstract

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.

Measuring the administered dose of particles on the facial mucosa of a realistic human model

“…The fluorescence intensity corresponded to the number of droplets deposited. Five eyelash lengths L were used, and the ratios of the eyes' width W to the length of the eyelashes were measured as 0.0 (without eyelashes), 0.1, 0.2, 0.4, and 0.8.Table 2,lists the relationship between L/W and the fluorescence intensity.The human eyelash normally ranges from 8.0 to 12.0 mm long 34. The average eye width of the volunteer in our study was 26.7 mm.…”

“…Oküler tutulumun izlendiği allerjik rinitli çocuklardaki kirpik uzunluğunun kontrole kıyasla anlamlı olarak daha fazla olduğu gösterilmiştir. 28 Bunun, artan konjonktival mast hücrelerinden salınan prostaglandine bağlı olabileceği düşünülmektedir. 28 Ayrıca, bazı atopik dermatit olgularında da trikomegali bildirilmiştir, ancak bu bulgunun koinsidental olup olmadığı netlik kazanmamıştır.…”

Eyelash trichomegaly: review of congenital, acquired, and drug‐associated etiologies for elongation of the eyelashes

“…The results showed that children with allergic rhinitis have eyelashes that are longer compared with a control group, and this difference was found to be statistically significant. The investigators postulated that local production of prostaglandins by conjunctival mast cells may play a role in eyelash length in individuals with allergic disease 36 …”
