AIM: To evaluate ocular surface functions in pregnant women with gestational diabetes mellitus(GDM)using Keratogragh 5M.

METHODS: Pregnant women with GDM and normal pregnant women were enrolled. All subjects were asked to answer ocular surface disease index(OSDI)questionnaire survey, and then underwent ophthalmic examination including tear meniscus height(TMH), average noninvasive Keratograph tear film break-up time(NIKBUTav), ocular redness analysis, and meibomial gland analysis.

RESULTS: There were no statistically significant differences in OSDI, TMH, NIKBUTav, eye redness analysis and meibomial gland analysis between the GDM group and the normal pregnant group(P>0.05). The OSDI scores were 8.02±4.25 and 7.50±4.28(P=0.557), TMH values were 0.22±0.05 and 0.20±0.04mm(P=0.158), NIKBUTav values were 8.01±2.15s and 8.02±1.53s(P=0.971).

CONCLUSION: There was no statistically significant difference between the GDM group and the normal pregnant group in ocular surface indexes. GDM had no negative effects on ocular surface, which may be related to good controlling of the blood glucose.
