Material and Methods: In this cross sectional study, patients above 20 years of age were screened randomly for dry eye. An 8 points questionnaires, slit lamp examination of meibomian glands, tear film breakup time, fluorescein staining of cornea, schirmer test were used to diagnose dry eye. The diagnosis was made when three of the five parameters were positive. The role of various occupations as well as role of different exposure factors like sunlight, excessive wind, smoking, drugs, and air pollution as dry eye risk factors was accessed. Result: Out of 445, 45.39% patients had dry eye. Dry eye prevalence was higher in those above 70 years of age (74%). It was higher in male population (51.82%) compare to female population (37.37%), nearly equal in rural (46.04%) and urban population (44.31%) and highest among factory workers (90%). Correlation of dry eye with drugs (P = 0.0002), sunlight/high temperature (P = 0.0003) and smoking (P = 0.03) were significant. Conclusion: This is a hospital based study which provides prevalence of dry eye in rural region of western Uttar Pradesh. It is more common in old age male population and significantly higher in factory workers. Out of different modifiable risk factors most important are drugs, sunlight/high temperature and smoking.展开更多
目的:探讨一种最新的眼表综合分析仪Keratograph对于泪膜稳定性评估的重复性和准确性,将其测量值与传统的检查方法进行比较。方法:采用Keratograph测量包括首次泪膜破裂时间(the first tear film break-up time,BUT-f)和平均泪膜破裂时...目的:探讨一种最新的眼表综合分析仪Keratograph对于泪膜稳定性评估的重复性和准确性,将其测量值与传统的检查方法进行比较。方法:采用Keratograph测量包括首次泪膜破裂时间(the first tear film break-up time,BUT-f)和平均泪膜破裂时间(the average tear film break-up time,BUT-ave)在内的非侵入式泪膜破裂时间(noninvasive tear film break-up time,NI_BUT)结果。测量结果的重复性使用变异系数(coefficient of variation,CV)和组内相关系数(intraclass correlation coefficient,ICC)进行评价,NI-BUT与传统的荧光素泪膜破裂时间(fluorescein tear film break-up time,FBUT)的比较采用Wilcoxon符号秩和检验,确定NI-BUT与FBUT,SchirmerⅠ试验结果的相关关系,采用BlandAltman分析进行一致性评价。结果:本研究纳入了48个受检者(48眼),平均年龄38.7±15.2岁。BUT-f的CV和ICC分别为12.6%和0.95,BUT-ave的为9.8%和0.96。BUT-f值低于FBUT值,差异有统计学意义(6.16±2.46s vs 7.46±1.92s,P<0.01)。NI-BUT与FBUT,SchirmerⅠ试验结果之间存在显著的正相关关系(P<0.01)。BUT-f与FBUT的95%一致性界限(limits of agreement,Lo A)范围为4.46s,BUT-ave与FBUT的Lo A范围为3.64s。结论:Keratograph能够提供具有较好重复性和可靠性的NI-BUT数据,在干眼诊治和角膜屈光性手术等领域有很好的应用前景。展开更多
