This article is from PLoS ONE, volume 9.AbstractObjective: To explore meibomian gland dysfunction MGD may determine the severity of dry eye conditions in visual display terminal VDT workers. Methodology: Prospective, case-control study carried out in China.106 eyes of 53 patients VDT work time 4 hour per day were recruited as the Long time VDT group; 80 eyes of 40 control subjects VDT work time ≤4 hour per day served as the Short time VDT group. A questionnaire of Ocular Surface Disease Index OSDI and multiple tests were performed. Three dry eye tests: tear film breakup time BUT, corneal fluorescein staining, Schirmer I test; and three MGD parameters: lid margin abnormality score, meibum expression assessment meibum score, and meibomian gland dropout degree meiboscore using Keratograph 5 M. Principal Findings: OSDI and corneal fluorescein score were significantly higher while BUT was dramatically shorter in the long time VDT group than the short time VDT group. However, the average of Schirmer tear volumes was in normal ranges in both groups. Interestingly, the three MGD parameters were significantly higher in the long time VDT group than the short time one P
