Choroidal Thickness Measurement in Myopic Eyes by Enhanced Depth Optical Coherence Tomography – Corrected Proof

Purpose: To measure choroidal thickness (CT) in myopic eyes using enhanced depth imaging (EDI).Design: A cross-sectional study.Participants: Fifty-six consecutive patients with spherical equivalent refractive error of at least 6 diopters (D) were evaluated.Methods: Enhanced depth imaging optical coherence tomography (OCT) images were obtained by positioning the spectral-domain OCT device close enough to the eye to acquire an enhanced signal of the choroidal layer. Choroidal depth was measured as the distance between the outer reflective retinal pigment epithelium (RPE) layer and the inner sclera border. Measurements were made in a horizontal fashion across the fovea at 500-μm intervals of the sections. (Read more...)
