Abstract:
Objective To measure the macular thickness of natural population in Changping district of Beijing by optical coherence tomography (OCT), and to analyze whether there is an increased thickness in diabetic patients.Methods In a cross-sectional population-based study, OCT was performed on 521 subjects (233 with normal glucose homeostasis, 174 with pre-diabetes and 114 with type 2 diabetes (T2D) according to 2011 Health Examination Survey of Changping.The subjects also received physical examination and laboratory measurements including fasting plasma glucose (FPG), oral glucose tolerance test (OGTT)-2 h plasma glucose and hemoglobin A1c (HbA1c).Results The results showed that central subfield thickness (CST) of the retina of men ((246±22) μm) was significantly greater than that of women ((235±26) μm) (P＜0.001).Meanwhile, no significant difference was found in the CST in subjects of different age, HbAlc and body mass index (BMI) (P＞0.05).Difference in thickness of different glucose groups was not seen in central subfield, inner subfields and outer subfields(P＞0.05).Conclusions Retina CST of men was significantly greater than that of women.No significant difference was found in the CST in subjects of different age, HbA1c and BMI.
