AIM: To study the correlation between meibomian gland dysfunction(MGD)patients and their sleep quality.METHODS: Retrospective case-control study. A total of 150 MGD patients treated in our hospital from January 2021 to October 2022 were selected and divided into sleep disorder group(75 cases, PSQI>10 points)and control group(75 cases, PSQI≤10 points)according to the Pittsburgh sleep quality index(PSQI). Both groups were scored using the ocular surface disease index(OSDI), underwent meibomian gland-related examinations(eyelid margin morphology, meibomian gland secretion ability, meibomian gland secretion quality score), corneal fluorescein staining(FL)score, Schirmer Ⅰ test(SⅠt), tear film break-up time(BUT)was measured, and sleep indicators(sleep quality, sleep latency, subjective sleep quality, sleep time)were evaluated.RESULTS: There were significant differences in OSDI score, FL score, SⅠt, BUT, eyelid margin morphology score, meibomian gland secretion ability score, and meibomian gland secretion quality score between the two groups(P<0.05). In the sleep disorder group, PSQI score, sleep latency score, subjective sleep quality score, and sleep time score were significantly positively correlated with OSDI score, FL score, meibomian gland secretion ability score, and meibomian gland secretion quality score(P<0.05); PSQI score, subjective sleep quality score, and sleep time score were significantly positively correlated with eyelid margin morphology score(P<0.05); PSQI score, sleep latency score, and subjective sleep quality score were significantly negatively correlated with BUT and SⅠt(P<0.05); sleep time score was significantly negatively correlated with BUT(P<0.05); sleep latency score was not significantly correlated with eyelid margin morphology score(P>0.05); sleep time score was not significantly correlated with SⅠt(P>0.05).CONCLUSION:The ocular surface condition of MGD patients is correlated with multiple sleep quality indicators, and a decline in sleep quality may increase the risk of MGD.
