    1. Differences In Macular Morphology Between Polypoidal Choroidal Vasculopathy And Exudative Age-Related Macular Degeneration Detected By Optical Coherence Tomography.

      Purpose: To evaluate the differences in the optical coherence tomographically determined macular morphology in eyes with polypoidal choroidal vasculopathy (PCV) from eyes with exudative age-related macular degeneration (AMD) quantitatively. Methods: The medical records of 208 eyes of 203 Japanese patients with PCV or exudative AMD who were newly treated for choroidal neovascularization were reviewed. The six linear, low-resolution, high-speed scans of 6 mm were analyzed using a manually assisted computer algorithm, which allowed us to manually draw spline lines arbitrarily on the images so that the subretinal fluid and neurosensory retina could be segmented. The thickness of the neurosensory retina ...

    2. Retinal Structural Changes Associated With Retinal Arterial Macroaneurysm Examined With Optical Coherence Tomography.

      Retinal arterial macroaneurysm can cause hemorrhagic and/or exudative complications. Eyes with minimal hemorrhage from the aneurysm often showed an extensive exudative change that extended to the fovea. In these eyes, retinal edema was seen predominantly in the outer nuclear layer, accompanying a focal serous retinal detachment beneath the fovea.Page: 782DOI: 10.1097/IAE.0b013e3181a2f26aAuthors: TSUJIKAWA, AKITAKA MD; SAKAMOTO, ATSUSHI MD; OTA, MASAFUMI MD; OH, HIDEYASU MD; MIYAMOTO, KAZUAKI MD; KITA, MIHORI MD; YOSHIMURA, NAGAHISA MD
