    8. Improving Glaucoma Detection Using Spatially Correspondent Clusters of Damage and by Combining Standard Automated Perimetry and Optical Coherence Tomography

      Improving Glaucoma Detection Using Spatially Correspondent Clusters of Damage and by Combining Standard Automated Perimetry and Optical Coherence Tomography
      PURPOSE. To improve the detection of glaucoma, techniques for assessing local patterns of damage and for combining structure and function were developed. METHODS. Standard automated perimetry (SAP) and frequency-domain optical coherence tomography (fdOCT) data, consisting of macular retinal ganglion cell plus inner plexiform layer (mRGCPL) as well as macular and optic disc retinal nerve fiber layer (mRNFL and dRNFL) thicknesses, were collected from 52 eyes of 52 healthy controls and ...

    9. The Locations of Circumpapillary Glaucomatous Defects Seen on Frequency-Domain OCT Scans

      The Locations of Circumpapillary Glaucomatous Defects Seen on Frequency-Domain OCT Scans
      Purpose. To examine the locations of local glaucomatous damage around the optic disc as seen in the circumpapillary retinal nerve fiber layer (RNFL) on frequency domain optical coherence tomography (fdOCT). Methods. Optic disc fdOCT volume scans from 54 healthy control eyes and 114 patient eyes, classified as suspected or mild glaucoma, were analyzed. All patient eyes had 24-2 visual fields (VFs) with mean deviations better than 5.5 dB. By ...

    10. Detecting Glaucoma with Visual Fields Derived from Frequency-Domain Optical Coherence Tomography

      Detecting Glaucoma with Visual Fields Derived from Frequency-Domain Optical Coherence Tomography
      Purpose. To compare the assessment of glaucomatous damage based on visual fields (VFs) derived from frequency-domain optical coherence tomography (OCT) to actual visual fields obtained from static automated perimetry. Methods. 84 eyes from 84 glaucoma patients or suspects and 128 eyes from 128 normal subjects were included.

      The “Inner Segment/Outer Segment Border” Seen on Optical Coherence Tomography is Less Intense in Patients with Diminished Cone Function
      Purpose: The integrity of the inner segment ellipsoid (ISe) band, previously called the inner segment/outer segment (IS/OS) border, seen on optical coherence tomography (OCT) is of clinical significance. To better understand the influence of cones on the appearance of this band, we examined the intensity of its signal in patients with diminished cone function.

      Automated segmentation of outer retinal layers in macular OCT images of patients with retinitis pigmentosa
      To provide a tool for quantifying the effects of retinitis pigmentosa (RP) seen on spectral domain optical coherence tomography images, an automated layer segmentation algorithm was developed.
