Abstract

Objective: Demodex folliculorum blepharitis is typically confirmed with lash epilation and microscopic identification of mites. However, mite counts may vary with the epilation technique. As there is no gold standard to epilating lashes for the purposes of mite counts, the aim of this study was to compare three epilation techniques.

Method: A prospective randomized double-blind study compared three epilation techniques on lashes with cylindrical dandruff. Techniques included (A) direct pulling of the lash; (B) rotating the lash before epilation; and (C) sliding the cylindrical dandruff away, lash rotation, and epilation. Mean mite counts were analyzed using a repeated-measures analysis of variance.

Results: Forty (n=40) participants (20 M: 20 F, mean age of 62.3±17.1 years) revealed similar mite counts between right (1.43±1.74) and left (1.35±1.59) eyes ( P =0.63). A significant difference ( P =0.03) in mite count was noted (technique A: 1.05 ± 1.60; technique B 1.76 ± 1.80; and technique C 1.36 ± 1.54) with technique B yielding the highest mite count ( P =0.04).

Conclusion: Demodex mite count is a key parameter in establishing infestation or to determine treatment efficacy. This study revealed that rotating the lash before epilation yielded the highest mite count. Future studies should report the epilation technique used to allow for study comparisons.

以毛囊线虫螨虫检索为目的的睫毛脱毛技术的双盲比较。

目的：毛囊虫睑缘炎通常通过睫毛脱毛和显微镜鉴定螨虫来确诊。然而，螨虫计数可能会因脱毛技术而异。由于目前还没有以螨虫计数为目的的睫毛脱毛金标准，本研究旨在比较三种脱毛技术：方法：一项前瞻性随机双盲研究比较了三种睫毛脱毛技术。脱毛技术包括：（A）直接拉扯睫毛；（B）在脱毛前旋转睫毛；以及（C）滑动圆柱形皮屑，旋转睫毛，然后脱毛。螨虫计数的平均值采用重复测量方差分析法进行分析：40 名参与者（20 名男性：20 名女性，平均年龄为 62.3±17.1 岁）的右眼（1.43±1.74）和左眼（1.35±1.59）的螨虫数量相似（P=0.63）。螨虫计数有明显差异（P=0.03）（技术 A：1.05±1.60；技术 B 1.76±1.80；技术 C 1.36±1.54），技术 B 的螨虫计数最高（P=0.04）：结论：螨虫计数是确定虫害或确定治疗效果的关键参数。本研究显示，在脱毛前旋转睫毛可获得最高的螨虫计数。今后的研究应报告所使用的脱毛技术，以便进行研究比较。

期刊介绍： Eye & Contact Lens: Science and Clinical Practice is the official journal of the Contact Lens Association of Ophthalmologists (CLAO), an international educational association for anterior segment research and clinical practice of interest to ophthalmologists, optometrists, and other vision care providers and researchers. Focusing especially on contact lenses, it also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed and published six times annually, it is a highly respected scientific journal in its field.
