All participants completed the Ocular Surface Disease Index(OSDI) questionnaire, ocular surface examination [Schirmer test, tear film breakup time(TFBUT), and ocular surface staining], and meibomian gland assessment [meiboscore(gland dropout detected on meibography using infrared camera of the Keratograph 5 M), meibum expressibility score(MES), meibum quality score(MQS), lid margin abnormality]. In addition, correlations of meibomian gland characteristics with ocular surface parameters as well as disease severity score were investigated in coGVHD group.RESULTS: The coGVHD group showed significantly higher meiboscore, MES, and MQS than the other 3 groups(all P<0.05). In the coGVHD group, parameters of meibomian gland showed a significant correlation each other and those of ocular surface. The correlation between meibomian gland parameters and severity score of co GVHD was also established(meiboscore, r=0.62; MES, r=0.47; MQS, r=0.47; lid margin abnormality score, r=0.55; all P<0.05).CONCLUSION: Patients with DED associated with co GVHD show poorer gland morphology and worse glandfunction than other types of DED. In addition, meibomian gland damage is not only associated with ocular surface damage but also disease severity of coGVHD.展开更多
