Aim: To assess the normal macular thickness measurements in healthy eyes of Iraqi volunteers and its variation by gender and age using cirrus HD optical coherence tomography.
Subjects and methods: This is a cross sectional study in a sample of healthy eyes of Iraqi volunteers to examine the macular thickness by optical coherence tomography at Ibn Alhaithem Teaching Eye Hospital. The samples were matched for age and gender.
Optical coherence tomography analysis was undertaken with cubic macular thickness analysis in six radial scans centered at fovea dividing the macula into nine quadrants according to ETDRS (Early Treatment Diabetic Retinopathy Study) as well as the total macular volume and mean macular thickness that also be assessed.
Results: Two hundred normal eyes of one hundred healthy Iraqi volunteers were examined clinically and scanned by optical coherence tomography. The mean of central foveal thickness was 245.65 ± 20.159 μm, the mean macular thickness was 277.64 ± 12.356 μm, and the macular volume was 9.995 ± 0.44 mm³. Central foveal thickness was clinically significantly greater in male gender with p<0.0001 and mean macular thickness and volume were also clinically significantly thicker in male than female with p<0.0001. Central foveal, mean macular thickness and volume changes were not clinically significant with age.
Conclusion: First normative macular thickness data in healthy Iraqi volunteers were obtained using cirrus HD OCT with a central foveal thickness measurements, mean macular thickness measurements were 245.65 ± 20.159 μm, 277.645 ± 12.356 μm respectively and the macular volume were 9.995 ± 0.442 mm³. The male macula is thicker than female macula.
