Abstract

Abstract: : Purpose: To determine whether axial length or refractive error influence the apparent thickness and contour of the central macula, as measured by optical coherence tomography (OCT). Methods: Prospective masked measurements (manifest refraction, A scans, and OCT) were performed on 80 eyes of 40 volunteers without diabetes or posterior segment pathology. Results: Foveal (147 ± 20 µm) and parafoveal (285 ± 15 µm) thickness were not correlated with refractive error (range, –4.75 to +3.125 diopters) or axial length (range, 21.60 to 25.81 mm). Conclusions: OCT measurements of central macula are consistent among emmetropic, moderately myopic, and moderately hyperopic eyes.
