    2. Possible Undiagnosed Glaucoma Detected by MultiColor Imaging of Retinal Diseases

      Possible Undiagnosed Glaucoma Detected by MultiColor Imaging of Retinal Diseases
      Purpose To evaluate for the presence of visible retinal nerve fiber layer (RNFL) defects consistent with undiagnosed glaucoma in MultiColor images (Heidelberg Engineering, Heidelberg, Germany) obtained at clinicians discretion for the diagnosis and management of retinal diseases. Design Retrospective chart review of MultiColor images obtained as part of routine clinical care between December 25, 2013 and June 24, 2014. Images were reviewed by 2 fellowship-trained glaucoma specialists (S.H.V ...

    3. IDENTIFICATION OF POSTERIOR SEGMENT PATHOLOGY WITH EN FACE RETINAL IMAGING USING MULTICOLOR CONFOCAL SCANNING LASER OPHTHALMOSCOPY

      IDENTIFICATION OF POSTERIOR SEGMENT PATHOLOGY WITH EN FACE RETINAL IMAGING USING MULTICOLOR CONFOCAL SCANNING LASER OPHTHALMOSCOPY
      Purpose: To assess posterior segment findings on multicolor confocal scanning laser ophthalmoscopy by correlation with spectral domain optical coherence tomography (SD-OCT) and to quantify agreement between these imaging modalities. Methods: Retrospective review of 159 eyes of 96 consecutive patients who underwent concurrent imaging with multicolor confocal scanning laser ophthalmoscopy and SD-OCT. Positive percent agreement and negative percent agreement were calculated for each finding identified on infrared, green, blue, and multicolor ...

    4. Comparison of Anterior Segment Optical Coherence Tomography Bleb Grading, Moorfields Bleb Grading System, and Intraocular Pressure After Trabeculectomy

      Comparison of Anterior Segment Optical Coherence Tomography Bleb Grading, Moorfields Bleb Grading System, and Intraocular Pressure After Trabeculectomy
      Purpose: To compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system and both with intraocular pressure (IOP) following trabeculectomy surgery. Materials and Methods: A novel AS-OCT grading system based on bleb size and internal reflectivity was developed. An imaging center was tasked with masked grading of AS-OCT images acquired by multiple surgical sites at postoperative week (POW) 2, postoperative month (POM ...

    6. Normal-Tension Glaucoma Masqueraders: Detection Using Optical Coherence Tomography

      Normal-Tension Glaucoma Masqueraders: Detection Using Optical Coherence Tomography
      Purpose: Optical coherence tomography (OCT) has become an important tool in the diagnosis and management of glaucoma; however, there can be overlap in the OCT findings between glaucoma and other diseases. We describe the clinical examination finings and interpretation of OCT imaging that led to the diagnosis of glaucoma masqueraders in a clinical case series. Materials and Methods: Four adult patients seen in the glaucoma clinic at the Duke Eye ...

    7. Pitfalls in Optical Coherence Tomography Imaging: Essentials for correct interpretation

      Pitfalls in Optical Coherence Tomography Imaging: Essentials for correct interpretation
      Optical coherence tomography (OCT) is widely used in the diagnosis and detection of glaucomatous progression. Many manufacturers make spectral-domain OCT (SD-OCT) devices, the most widely used type of OCT. In contrast to time-domain OCT, with SD-OCT, a greater area of the retina can be measured without interpolation of data. Additionally, the anterior segment can be imaged using the same machine. Most OCT machines have built-in proprietary software that can measure ...

    8. Artifacts in Spectral-Domain Optical Coherence Tomography Measurements in Glaucoma

      Artifacts in Spectral-Domain Optical Coherence Tomography Measurements in Glaucoma
      Importance Spectral-domain optical coherence tomography (SD-OCT) has an integral role in the diagnosis and treatment of glaucoma. Understanding the types of artifacts commonly seen in the imaging of patients being evaluated for glaucoma will help physicians better implement these data in the care of patients. Objectives To determine the frequency and distribution of SD-OCT imaging artifacts in patients being evaluated for glaucoma and to provide examples of common artifacts. Design ...

    9. Reproducibility of Spectral-Domain Optical Coherence Tomography Measurements in Adult and Pediatric Glaucoma

      Reproducibility of Spectral-Domain Optical Coherence Tomography Measurements in Adult and Pediatric Glaucoma
      Purpose: To determine the reproducibility of spectral-domain optical coherence tomography (OCT) measurements of peripapillary retinal nerve fiber layer (RNFL) and macular retinal thickness of the central 20-degree area of the posterior pole in adult and pediatric glaucoma and normal subjects. Methods: Normal, glaucoma suspect and glaucoma eyes of adult and pediatric subjects were recruited. Spectralis OCT scans were obtained 3 times on the same day (intravisit) and 4 weeks later ...

    10. Beyond the Retinal Nerve Fiber Layer: What are the New Approaches in 2012?

      Beyond the Retinal Nerve Fiber Layer: What are the New Approaches in 2012?
      Glaucoma diagnosis with imaging devices is difficult because of the variation in axonal count amongst normals. The convergence point of all axons is the optic nerve head and peripapillary retinal nerve fiber layer (RNFL). However, a majority of the ganglion cells (from which the RNFL originates) reside in the macula (40% of the retinal thickness) and since their numbers are relatively constant amongst normals 1, it may be another valuable ...
