    1. The correlation between optical coherence tomography retinal shape irregularity and axial length

      The correlation between optical coherence tomography retinal shape irregularity and axial length

      Purpose To describe the retinal contour in optical coherence tomography (OCT) images, and report the relationship between retinal contour and axial length. Methods Retinal contour was defined by the path of the retinal pigment epithelial (RPE) line in macular and extra-macular OCTs of 70 eyes of 70 participants recruited from ophthalmology clinics in South Australia. The shape of this contour was described by the best-fit curvature (K), and Fourier analysis of the difference between K and the RPE. The Fourier transformation was summarised by total difference (sumdiff), maximum single frequency difference (MaxE), and root mean square difference (rmse) between each ...

    2. Early imaging of a macular hole following vitrectomy with primary silicone oil tamponade

      Early imaging of a macular hole following vitrectomy with primary silicone oil tamponade
      Background: To describe the morphology of a macular hole in the early postoperative period following vitrectomy with primary silicone oil tamponade. Methods: A case report with optical coherence tomography (OCT) scans prior to surgery, at 20 minutes postoperatively and then at 17 hours postoperatively. Results: OCT images of a 73-year-old woman with a stage 3 macular hole were obtained. At 20 minutes postoperatively, there was a reduction in intraretinal cysts and a reduction in macular hole size with elevated-open configuration. At 17 hours postoperatively, complete macular hole closure was noted. Conclusion: OCT Images of a macular hole in the early ...
