Popis: Purpose. To analyze and compare choroidal thickness between keratoconus (KC) patients and age-matched non-KC subjects. Methods. A cross-sectional, case-control study. One hundred and thirty-four keratoconic eyes and 78 control eyes, from individuals aged from 12 to 30 years old, were studied. Patients with KC followed in Corneal Department of Centro Hospitalar São João, Porto, Portugal, were identified and consecutively included between December 2017 and February 2018. A spectral-domain optical coherence tomography (OCT) using depth enhanced imaging was performed, and choroidal thickness in the center of the fovea and at 500 μm intervals along a horizontal section was measured and compared. Results. The statistical analysis showed that keratoconic eyes present a thicker choroid in every measured location (p
