The comparison of the diagnostic efficiency of a reference method (light microscopy [LM] using 10% potassium hydroxide [KOH]) with the use of 100% alcohol to confocal microscopy (IVCM) for the detection of eyelid infestation in seborrheic blepharitis patients.
Eyelashes were epilated from the right eyes for the reference method and the left eyes for the alcohol group in 58 eyes of 29 patients. IVCM was used on the left eyes. The primary outcomes were the number of mites per lash and the rate of positivity (≥1 mite).
The rate of positivity was similar among the three groups (KOH: 82.8%, alcohol: 86.2%, IVCM: 72.4%; >.05). The mean number of mites per lash in the KOH group (1.5 ± 1.3) was higher than in the alcohol (0.9 ± 0.6, =.041) and IVCM groups (0.9 ± 0.9, =.036).
KOH was found to be superior in terms of the quantification of mites compared to alcohol and IVCM.
比较参照方法（使用 10%氢氧化钾[KOH]的光学显微镜[LM]）与 100%酒精对脂溢性睑缘炎患者的眼睑感染的检测的诊断效率。
对 29 例 58 只眼的右眼进行睫毛拔除法（参照方法），左眼进行酒精组。使用共焦显微镜（IVCM）对左眼进行检测。主要结局是每根睫毛上的螨虫数量和阳性率（≥1 只螨虫）。
三组的阳性率相似（KOH：82.8%，酒精：86.2%，IVCM：72.4%；>.05）。KOH 组每根睫毛上的螨虫平均数（1.5±1.3）高于酒精组（0.9±0.6，=0.041）和 IVCM 组（0.9±0.9，=0.036）。
与酒精和 IVCM 相比，KOH 在螨虫的定量方面更具优势。
