Choroidal thickness in healthy subjects

PURPOSE: To measure the choroidal thickness by enhanced depth imaging optical coherence tomography (EDI-OCT) in normal eyes. METHODS: In a prospective case series, 208 eyes of 104 normal Iranian subjects were enrolled. Complete ophthalmic examination was performed. Inclusion criteria were best corrected visual acuity (BCVA) ≥20/20, ≤ ±1 diopter of refractive error in either spherical or cylindrical components, normal intraocular pressure (IOP) and no systemic or ocular diseases. The choroidal thickness was measured by EDI-OCT subfoveally, and 1500 μm and 3000 μm nasal and temporal to the fovea. CONCLUSION: In normal Iranian subjects participating in this study, mean choroidal thickness was comparable with other reports.
