    7. Optical coherence tomography characteristics of taxane-induced macular edema and other multimodal imaging findings

      Optical coherence tomography characteristics of taxane-induced macular edema and other multimodal imaging findings
      Purpose To identify common optical coherence tomography (OCT) characteristics of taxane-related CME (T-CME) to differentiate it from CME associated with other causes (O-CME) and to present multimodal imaging findings of T-CME. Methods To differentiate T-CME from O-CME, pooled SD-OCT images from 14 previous publications and images obtained from our multicenter case series of 3 patients with multimodal imaging of T-CME were compared with 16 consecutive cases of O-CME. Images were ...

    8. Linear and planar reflection artifacts on swept-source and spectral-domain optical coherence tomography due to hyperreflective crystalline deposits

      Linear and planar reflection artifacts on swept-source and spectral-domain optical coherence tomography due to hyperreflective crystalline deposits
      Purpose To describe novel spectral-domain (SD) and swept-source (SS) optical coherence tomography (OCT) linear and planar reflection artifacts produced by hyperreflective crystalline deposits (HCD). Methods Imaging from 10 eyes with HCD producing linear and planar artifacts on OCT was retrospectively analyzed. All eyes had SD-OCT (Spectralis HRA+OCT, Heidelberg Engineering, Germany) and SS-OCT angiography (PLEX Elite 9000, Carl Zeiss Meditec, Inc., Dublin, CA) acquired on the same day. The horizontal ...

    9. Macroaneurysms Associated With Congenital Retinal Macrovessels

      Macroaneurysms Associated With Congenital Retinal Macrovessels
      Purpose: Congenital retinal macrovessels are large aberrant retinal blood vessels that cross the horizontal raphe and can traverse the central macula. Using multimodal imaging and optical coherence tomography angiography, we describe 2 cases of congenital retinal macrovessel associated with macroaneurysms. Methods: Two patients presented for evaluation and were found to have congenital retinal macrovessels associated with macroaneurysms. Color photography, optical coherence tomography, fundus autofluorescence fluorescein angiography, and optical coherence tomography ...

    10. Optical Coherence Tomography Angiography in a Patient With Diabetes and Preretinal Neovascularization

      Optical Coherence Tomography Angiography in a Patient With Diabetes and Preretinal Neovascularization
      A 39-year-old patient with type 2 diabetes (diagnosed in 1996) presented for an evaluation of bilateral proliferative diabetic retinopathy that had been treated previously with panretinal photocoagulation. His visual acuity was 20/25 OD. Examination by ophthalmoscopy showed scattered dot-blot intraretinal hemorrhages and an inferotemporal preretinal neovascular frond ( Figure , A). Optical coherence tomography angiography was also performed ( Figure , B).
