概要:伴隨性外斜視成人眼部不適癥狀明顯,患者眼表炎癥的存在可能是伴隨性外斜視與干眼癥之間的重要介質(zhì)。Oculus Keratograph眼綜合分析儀檢測(cè)無創(chuàng)淚液破裂時(shí)間、無創(chuàng)淚液高度和眼紅指數(shù),同時(shí)進(jìn)行眼表疾病指數(shù)和shirmer I測(cè)試。通過Simoa技術(shù),在伴外斜視的患者和年齡和性別匹配的健康對(duì)照者的眼淚中檢測(cè)到IL-6、IL-10、IL-17A、IL-12P70、INF-γ和TNF-α的水平。伴有外斜視的患者IL-6(4:683 ± 1:329)pg/mL顯著高于正常組(1:455 ± 0:391)pg/mL,p = 0:0304;颊叩腡NF-α(0:2095 ± 0:0703)pg/mL也顯著高于正常組(0:0513 ± 0:0149)pg/mL,p = 0:0397。斜視患者與正常對(duì)照組炎癥因子水平如下:IL 17A(0.1551 pg/mL:0.0793 pg/mL)、IL-10(0.3358 pg/mL:0.0513 pg/mL)、IL-12p70 (0.0253 pg/mL:0.0099 pg/mL)和INF-γ(0.0284 pg/mL:0.009 pg/mL),且伴隨斜視的中位數(shù)是對(duì)照組的1.96-6.55倍。伴外斜視患者淚液中高水平的炎性細(xì)胞因子可能是促進(jìn)伴外斜視患者發(fā)生干眼癥的潛在因素。參考文獻(xiàn):
