Purpose: To compare choroidal thickness between smokers and nonsmokersby utilising swept source optical coherence tomography.Material and Methods: A total of 80 subjects were included this study. Fortypatients were nonsmokers and 40 patients were smokers with a minimum historyof 10 years of smoking. Swept source optical coherence tomography was usedto calculate central choroidal thickness as well as choroidal thicknessmeasurements at varying distances from centre of fovea temporally and nasally.All subjects were asked to refrain from smoking at least 8 hours beforemeasurements.Results: The choroidal thickness measurements did not vary between smokersand non smokers when measured on swept source optical coherencetomography. The duration of smoking also did not seem to influence choroidalthickness (p-value = 0.280).Conclusion: Chronic smoking does not seem to influence choroidal thicknesswhen compared to healthy non smokers.Keywords: Swept source optical coherence tomography, choroidal thickness,smokers
