Purpose: To measure average values of foveal thickness, by Optical Coherent Tomography (OCT) in a pediatric population and to determine significant differences between sex, age and refractive status. Methods: A prospective, transversal, descriptive and observational study was undertaken to determine the foveal thickness in children between the ages of 5 and 15 years. They were randomly selected in a comprenhensive ophthalmology consultation at an Eye Hospital. We included every patient independently of the refractive status. We excluded any patient with other ocular pathology. A macular OCT mapping was performed: 6 radii in each eye of 5.92 mm in length each, starting always with the right eye and the first radius of vertical scan centred on the fovea. Results: Forty eyes have been measured in 20 children, average age 9.2 years, males 60.9% with a refractive defect of - 4.75 to + 2.00 (shperic equivalent) average foveal thickness: 162.7 +/- 11.9 mm. Conclusion: In this pediatric population, age, sex and refractive status were not associated to a significant variation of foveal thickness mesured by OCT.
