Macular Thickness Measurement in Normal Subjects with Respect to Age and Gender Using Cirrus HD-OCT in Rasht City

To measure macular thickness in normal subjects with respect to age and gender using Cirrus HD-OCT in Rasht city.
In this cross-sectional study, 112 normal subjects were randomly selected. Both eyes of each subject were included and all subjects underwent complete eye examinations. Macular thickness map protocol with macular cube 512×128 was selected, and the average thickness of the retina was determined in nine ETDRS regions. To assess the reproducibility and the system’s degree of confidence, the thickness of the retina was measured up to five times in ten healthy subjects, and then the coefficient of variation was measured for each individual. All obtained data were analyzed using SPSS statistical software version 16.
The coefficient of variation of macular thickness was 0.15-1.33% in the 1-mm central area. The mean±SD of central subfield thickness (CST), macular thickness (MT), and macular volume (MV) were 245.44±20.39 µm, 277.9±11.95 µm and 9.98±0.43 mm3, respectively. The mean CST (p The mean macular thickness in healthy subjects was 280.67±12.79 µm in men and 276.63±11.61 µm in women with 95% confidence interval. This value was significantly greater in men than women
