Background/aims To correlate visual acuity in highly myopic eyes without macular disease with retinal and choroidal thickness as measured by spectral-domain optical coherence tomography (OCT). Methods 60 eyes of 46 highly myopic patients (spherical equivalent ≥−6 D or axial length ≥26 mm) were studied in a clinical setting. Eyes with any clinical evidence of maculopathy or amblyopia were excluded. Eyes were imaged using the 3D-2000 OCT (Topcon Corporation, Tokyo, Japan). Two independent investigators manually measured: choroidal thickness at 500-μm intervals up to 2500-μm nasal and temporal to the fovea, subfoveal choroidal thickness, foveal thickness, outer nuclear layer and photoreceptors i
