Abstract:
Objective Using MRI techniques and the FreeSurfer software package to research the occipital lobe's surface area in children with ametropic amblyopia.Design Prospective,nonrandomized clinical trial.Participants The amblyopic group included 10 children with ametropic amblyopia.The control group included 10 children with normal sight.Methods The brain MRI scan was per- formed with SIEMENS AVANTO 1.5 Tesla scanner.For the surface area analysis,3-demensional MPRAGE images were analyzed with FreeSurfer software package.Main Outcome Measures Occipital lobe related surface area(cuneus,later occipital,lingual,perical- carine)of bilateral hemisphere.Results No difference was between the ages of the two groups.The surface areas of the lingual,pefical- carine,cuneus of bilateral hemisphere and lateraloccipital on the left hemisphere in amblyopic patients were smaller than those of nor- real children(P
