Forty<br>patients were nonsmokers and 40 patients were smokers with a minimum history<br>of 10 years of smoking. Swept source optical coherence tomography was used<br>to calculate central choroidal thickness as well as choroidal thickness<br>measurements at varying distances from centre of fovea temporally and nasally.<br>All subjects were asked to refrain from smoking at least 8 hours before<br>measurements.<br>Results: The choroidal thickness measurements did not vary between smokers<br>and non smokers when measured on swept source optical coherence<br>tomography. The duration of smoking also did not seem to influence choroidal<br>thickness (p-value = 0.280).<br>Conclusion: Chronic smoking does not seem to influence choroidal thickness<br>when compared to healthy non smokers.<br>Keywords: Swept source optical coherence tomography, choroidal thickness,<br>smokers</p> ER -
