PURPOSE: To study the relationship between meibomian secretion and dry eye.
METHODS: To observe 68 outpatients (136 eyes) consecutively. Routine check up included vision, anterior segment and fundus, scoring of tear break up time (BUT), Schirmer I test and rose bengal staining (rb). Recorded the property of meibomian secretion. Defined the dry eye as mild and severe.
RESULTS: Meibomian secretion was sorted as egg-white-like secretion (n=28), milk-yellowish secretion (n=26), granular secretion (n=30) and toothpaste-like secretion (n=52). The result declared that BUT and rb scoring stepped up consecutively in the above secretions, that was higher in toothpaste-like secretion than in other groups (all P < 0.01). Schirmer I scoring was below 1 in all groups, and there was no difference in the groups. Fifty-four eyes (40%) met the criteria of dry eye syndrome. The incidence of dry eye stepped up in groups as egg-white-like secretion (2/28) 7.1%, milk-yellowish secretion (4/26) 15%, granular secretion (8/30) 27% and toothpaste-like secretion (40/52) 77%. The incidence was higher in granular secretion than in egg-white-like secretion (P < 0.05), while the incidence was higher in toothpaste-like secretion than in any of other 3 groups (P < 0.01). There was no severe dry eye in egg-white-like secretion and milk-yellowish secretion, while dry eye was found in 2 out of 8 in granular secretion, and in 19 out of 40 in toothpaste-like secretion. Incidence of severe dry eye was found higher in toothpaste-like secretion than in non toothpaste-like secretion (P < 0.05).
CONCLUSION: Abnormal meibomian secretion affects the stability of ocular surface. The patients with toothpaste-like secretion are prone to dry eye and tend to have a worse dry eye than other secretion groups.
