Study on relationship between meibomian glands and ocular symptoms in patients with dry eyes
Objective To explore the relationship between meibomian glands and ocular symptoms in patients with dry eyes.Methods This study was a non-interventional and observational trial involved 34 eyes from 17 patients diagnosed as dry eyes during June 20th,2012 to July 10th,2012.Ocular Surface Disease Index(OSDI),Schirmer test and tear film break-up time(BUT) were measured,the opening of meibomian glands was examined by using noncontact meibographic system.Results Among these patients,average OSDI was 28.76±15.60,mean SIaT was 7.38±7.19 mm,mean BUT was 3.00±1.00 s,mean opening scores of meibomian glands was 3.57 1.12,and scores of corneal fluorescein staining were 0.35±1.19.Conclusion The meibomian gland opening scores and corneal fluorescein staining scores are closely related to ocular symptoms in patients with dry eyes,and the view-point of treatment of meibomian gland disease may be the direction for treatment of dry eyes.
