    1. Automated 3D segmentation of intraretinal layers from optic nerve head optical coherence tomography images

      Automated 3D segmentation of intraretinal layers from optic nerve head optical coherence tomography images
      Optical coherence tomography (OCT), being a noninvasive imaging modality, has begun to find vast use in the diagnosis and management of ocular diseases such as glaucoma, where the retinal nerve fiber layer (RNFL) has been known to thin. Furthermore, the recent availability of the considerably larger volumetric data with spectral-domain OCT has increased the need for new processing techniques. In this paper, we present an automated 3-D graph-theoretic approach for the segmentation of 7 surfaces (6 layers) of the retina from 3-D spectral-domain OCT images centered on the optic nerve head (ONH). The multiple surfaces are detected simultaneously through the ...

    2. Macular Holes and Macular Pucker: The Role of Vitreoschsis as Imaged By Optical Coherence Tomography/Scanning Laser Ophthalmoscopy

      Macular Holes and Macular Pucker: The Role of  Vitreoschsis as Imaged By Optical Coherence Tomography/Scanning Laser Ophthalmoscopy
      Purpose The pathogenesis of macular pucker and macular holes is poorly understood. Anomalous posterior vitreous detachment (PVD) and vitreoschisis have been proposed as possible mechanisms. This study used clinical imaging to seek vitreoschisis and study the topographic features of macular pucker and macular holes. Methods Combined optical coherence tomography and scanning laser ophthalmoscopy (OCT/SLO) was performed in 45 eyes with macular hole and 44 eyes with macular pucker. Longitudinal imaging was used to identify vitreoschisis and measure retinal thickness. The topographic features of eyes with macular hole with eccentric macular contraction were compared to 24 eyes with unifocal macular ...

    3. Multifocal Retinal Contraction In Macular Pucker Analyzed By Combined Optical Coherence Tomography/Scanning Laser Ophthalmoscopy.

      Optical coherence tomography/scanning laser ophthalmoscopy imaging of macular pucker revealed multifocal retinal contraction and identified increased retinal damage with more foci of retinal contraction.Page: 447DOI: 10.1097/IAE.0b013e318160a754Authors: GUPTA, PRIYA BS *+; SADUN, ALFREDO A.
