Abstract
PURPOSE We sought to investigate the association of meibomian gland morphology with lid margin abnormalities in patients with meibomian gland dysfunction. METHODS This retrospective study included 368 eyes of 184 patients. Meibography was used to evaluate meibomian gland (MG) morphological features, such as dropout, distortion, thickened ratio and thinned ratio. Lid margin photography was used to evaluate lid margin abnormalities including orifice plugging, vascularity, irregularity and thickening. The association between MG morphological features and lid margin abnormalities was analyzed using a mixed linear model. RESULTS The study found a positive correlation between plugging of gland orifices grade and MG dropout grade in both the upper lids (B = 0.40, p = 0.007) and the lower lids (B = 0.55, p = 0.001). Plugging of gland orifices grade was also positively correlated to MG distortion grade in the upper lids (B = 0.75, p = 0.006). In the upper lids, MG thickened ratio increased first (B = 0.21, p = 0.003) and then decreased (B = - 0.14, p = 0.010) with a higher lid margin thickening grade. MG thinned ratio was negatively correlated with lid margin thickening (B = - 0.14, p = 0.002, B = - 0.13, p = 0.007). MG distortion grade decreased with lid margin thickening (B = - 0.61, p = 0.012). CONCLUSION Orifice plugging was correlated to meibomian gland distortion and dropout. Lid margin thickening was associated with meibomian gland thickened ratio, thinned ratio, and distortion. The study also suggested that distorted and thinned glands may be transitional phases between thickened glands and glands dropout.

Abstract
PURPOSE Familial Mediterranean fever (FMF) is an idiopathic disease with chronic inflammation. We aimed to determine the changes caused by the chronic inflammatory nature of FMF on the ocular surface, meibomian glands (MG), and conjunctiva via conjunctival impression cytology (CIC). MATERIAL-METHOD Forty-two FMF patients with a mean age of 11.93±3.92 years and 36 control patients with a mean age of 11.83±3.38 years were included in the study. Ocular surface anomalies of the patients were evaluated using Schirmer II, TBUT and OSDI. MG function (meibum quality), morphology (meiboography), and CIC were evaluated. RESULTS Although there was a significant difference between the groups in terms of Schirmer II and TBUT, OSDI scores did not significantly differ (P=0.022, 0.010, and 0.099 respectively), and no significant dry eye sign was observed in either group. There was significant difference between the groups in terms of the percent area of MG dropout, MG density, meiboscore (P=0.020, 0.023, and 0.031 respectively), but no significant difference was observed in relation to MG quality (P=0.650). Although conjunctival impression cytology was of a higher grade in the patients with FMF according to Nelson's classification, no significant difference was observed between the groups (P=0.109). CONCLUSION Although there was a decrease in the number of MGs in FMF patients, no significant deterioration was observed in conjunctival cytology. In these patients, tear film stability may deteriorate in particular. Clinicians should be aware of the possibility of ocular surface disease secondary to MG dropout in patients with FMF.
