Sumario: | 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. RESULTS: Mean age was 34.6 ± 9.8 years (range, 18–57 years). Mean subfoveal choroidal thickness was 363 ± 84 μm. Choroidal thickness was 292 ± 76 and 194 ± 58 μm at 1500 and 3000 μm nasal to the fovea, respectively, and 314 ± 77 and 268 ± 66 μm at 1500 and 3000 μm temporal to the fovea, respectively. There was no statistically significant difference in the choroidal thickness between sexes and laterality of the eyes. Choroidal thickness at fovea (P < 0.001) and at all extrafoveal locations decreased significantly for every 10 years increase in age. CONCLUSION: In normal Iranian subjects participating in this study, mean choroidal thickness was comparable with other reports. |
