    2. Hypotony Maculopathy: A Silent Mimicker of Common Macular Diseases With Nonspecific Optical Coherence Tomography Findings

      Hypotony Maculopathy: A Silent Mimicker of Common Macular Diseases With Nonspecific Optical Coherence Tomography Findings
      Purpose: To highlight the diagnostic challenge of eyes with hypotony maculopathy with concurrent macular diseases and to present optical coherence tomography (OCT) imaging findings in hypotony maculopathy. Methods: Retrospective review of 15 eyes of 12 patients with hypotony maculopathy at a single institution. Results: Low intraocular pressure (IOP) was caused by overfiltration from trabeculectomy in 9 eyes (of 15, 60%), overtreatment with topical aqueous suppressants after trabeculectomy in 3 eyes ...

    3. Structural and Functional Associations of Macular Microcirculation in the Ganglion Cell-inner Plexiform Layer in Glaucoma Using Optical Coherence Tomography Angiography

      Structural and Functional Associations of Macular Microcirculation in the Ganglion Cell-inner Plexiform Layer in Glaucoma Using Optical Coherence Tomography Angiography
      Purpose: To quantify retinal microvasculature within the macular ganglion cell-inner plexiform layer (GCIPL) in primary open angle glaucoma (POAG) and normal eyes, determine association of vessel parameters with structural and functional measures, and report diagnostic accuracy of vessel parameters. Methods: POAG and normal patients underwent 6▒mm6▒mm macula scans (Angioplex TM optical coherence tomography angiography [OCTA]; Cirrus TM HD-OCT 5000); and Humphrey Field Analyzer II-i 24-2 visual field (VF ...

    5. Sickle cell disease and the eye

      Sickle cell disease and the eye
      Purpose of review To review recent literature pertaining to sickle cell retinopathy (SCR) and, in particular, sickle cell maculopathy. Recent findings Several recent studies suggest that macular perfusion abnormalities seen in patients with sickle cell disease of various genotypes may affect both the superficial and deep capillary plexi, with a predilection for the deep capillary plexus. Further, these changes may be associated with areas of macular thinning, as well as ...

    6. Utility of optical coherence tomography angiography in detecting glaucomatous damage in a uveitic patient with disc congestion: A case report

      Utility of optical coherence tomography angiography in detecting glaucomatous damage in a uveitic patient with disc congestion: A case report
      Purpose To report a case of uveitic glaucoma with congested optic disc where optical coherence tomography angiography (OCT-A) provided diagnostic utility in assessing glaucomatous damage but optical coherence tomography (OCT) alone had limited utility. Observations We report a case of a 33-year-old Caucasian female referred to the USC Roski Eye Institute for uncontrolled intraocular pressure (IOP) in the left eye. She was managed by an outside provider for 6 months ...

    7. Comparison of Glaucoma Progression Detection by Optical Coherence Tomography and Visual Field

      Comparison of Glaucoma Progression Detection by Optical Coherence Tomography and Visual Field
      Purpose To compare longitudinal glaucoma progression detection using optical coherence tomography (OCT) and visual field (VF). Design Validity assessment Method We analyzed subjects with more than 5 follow-up visits (every 6 months) in the multi-center Advanced Imaging for Glaucoma Study. Fourier-domain optical coherence tomography (OCT) was used to map the thickness of the peripapillary retinal nerve fiber layer (NFL) and ganglion cell complex (GCC). OCT-based progression detection was defined as ...

    8. ELHnet: a convolutional neural network for classifying cochlear endolymphatic hydrops imaged with optical coherence tomography

      ELHnet: a convolutional neural network for classifying cochlear endolymphatic hydrops imaged with optical coherence tomography
      Detection of endolymphatic hydrops is important for diagnosing Menieres disease, and can be performed non-invasively using optical coherence tomography (OCT) in animal models as well as potentially in the clinic. Here, we developed ELHnet, a convolutional neural network to classify endolymphatic hydrops in a mouse model using learned features from OCT images of mice cochleae. We trained ELHnet on 2159 training and validation images from 17 mice, using only the ...

      Repeatability and Reproducibility of Superficial Macular Retinal Vessel Density Measurements Using Optical Coherence Tomography Angiography En Face Images
      Importance The repeatability and reproducibility of quantitative metrics from optical coherence tomographic angiography (OCTA) must be assessed before these data can be confidently interpreted in clinical research and practice. Objective To evaluate the repeatability and reproducibility of OCTA-derived retinal vascular quantitative metrics. Design, Setting and Participants In this cross-sectional study, 21 healthy volunteers (42 eyes) and 22 patients with retinal disease (22 eyes), including 14 with age-related macular degeneration, 3 ...
