Choroidal Thickness in Mild Autonomous Cortisol Secretion

To evaluate the patients with mild autonomous cortisol secretion (MACS) by means of choroidal thickness (CT) and also investigate whether CT may be a diagnostic tool in the management of MACS or not. Twenty-seven patients with MACS and 25 age-sex-matched healthy controls were enrolled in this cross-sectional comparative study. All the participants underwent CT measurement by using Spectralis optical coherence tomography (Heidelberg Engineering, Heidelberg, Germany) with enhanced deep imaging mode at the subfoveal, 500-1000-1500 µm nasal and 500-1000-1500 µm temporal to the foveola. The groups were similar in terms of spherical equivalence, age and axial lengths. The mean CT was significantly thicker in patients with MACS than controls in all measurement quadrants (p
