ABSTRACT Purpose To compare subfoveal choroidal thickness (SFCT) between patients with nanophthalmos and agematched controls. Methods This prospective, cross-sectional and comparative study included 31 eyes from 31 patients with nanophthalmos (study group) and 31 eyes from 31 healthy subjects (control group). SFCT and central macular thickness (CMT) were measured with spectral domain optical coherence tomography. All participants underwent a standardised ocular examination including best corrected visual acuity (BCVA), central corneal thickness (CCT), anterior chamber depth (ACD) and refractive error (RE) measurements. Results Mean SFCT in the nanophthalmic eyes and in the control eyes were 551.3±87 mm and 330.5±46 mm, respectively ( p
