【摘要】:目的检测干眼患者泪膜脂质层厚度(lipid layer thickness,LLT),并分析LLT与眼表体征之间的相关性。方法纳入130例(130眼)干眼患者为本研究研究对象,其中睑板腺功能障碍(meibomian gland dysfunction,MGD)患者64例,非MGD患者66例,进行LLT检测、泪膜破裂时间(break-up time,BUT)检查、角膜荧光素染色(fluorescein staining,FL)、Marx线(Marx line,ML)评分及SchirmerⅠ试验。分析不同年龄段LLT分布情况,及其与其他检查之间的相关性。结果不同年龄段之间LLT差异有统计学意义(P=0.007),各年龄段男性与女性之间LLT差异均无统计学意义(均为P0.05)。LLT与年龄呈正相关(r=0.334,P0.001),LLT与性别无显著相关性(r=0.107,P=0.226)。LLT与上睑ML评分(r=0.295,P=0.001)、下睑ML评分(r=0.233,P=0.008)呈正相关,与BUT、FL及泪液分泌量均无显著相关性(均为P0.05)。MGD组LLT与上睑ML评分、下睑ML评分呈正相关(均为r=0.306,P=0.014),与其他检查指标均无显著相关性(均为P0.05)。非MGD组LLT与其他检查指标均无显著相关性(均为P0.05)。多元线性回归分析结果显示,干眼患者中,年龄、上睑ML评分与LLT存在线性关系(年龄:β=0.254,P=0.005;上睑ML评分:β=0.207,P=0.022),在MGD组中,仅年龄与LLT存在线性关系(β=0.382,P=0.002)。MGD组上睑ML评分及下睑ML评分均高于非MGD组(均为P0.001)。结论干眼患者LLT与年龄、ML评分呈正相关。泪膜LLT检测作为干眼诊断的辅助检查时,需结合年龄等影响因素进行综合分析。
