Retinal thickness in healthy and diabetic subjects measured using optical coherence tomography mapping software.

摘要: PURPOSE. To define the normal retinal thickness in healthy subjects using optical coherence tomography (OCT) mapping software and to assess ability of OCT detect early macular thickening diabetic patients. METHODS. Six radial scans centered on fixation point were done 60 eyes 70 35 patients without edema biomicroscopy. Retinal was measured automatically with software. Mean compared subgroups based age, sex, eye, subjects. Thickening diagnosed if mean an area greater than + 2SD corresponding subjects; or difference between right left eye exceeded 2 SD a given RESULTS. In subjects, central 1000 µm diameter 170±18 µm. There no significant according but significantly men women (p=0.0139). No observed biomicroscopy , detected 12 eyes. CONCLUSIONS. this study average local variations population defined commercially available seems sensitive tool for detecting thickening. (Eur J Ophthalmol 2002; 12: 102-8)
