    1. SENSITIVITY OF 840-nm SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN DETECTING TYPE 1 NEOVASCULARIZATION ACCORDING TO THE HEIGHT OF THE ASSOCIATED PIGMENT EPITHELIAL DETACHMENT

      SENSITIVITY OF 840-nm SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN DETECTING TYPE 1 NEOVASCULARIZATION ACCORDING TO THE HEIGHT OF THE ASSOCIATED PIGMENT EPITHELIAL DETACHMENT

      Purpose: To evaluate the ability of optical coherence tomography angiography (OCTA) to detect abnormal vascular blood flow in Type 1 neovascularization (NV) with or without significant pigment epithelial detachment (PED). Methods: Consecutive age-related macular degeneration patients with either treatment-naive or anti–vascular endothelial growth factor–treated Type 1 NV were divided into 2 groups based on the PED height on structural OCT: greater than 250 μ m (Group 1) versus less than 250 μ m (Group 2). Two independent senior retina specialists analyzed the OCTA images (Zeiss Angioplex OCT, Carl Zeiss AG, Jena, Germany) using the automatic slabs alone (first reader) versus ...

    2. Optical Coherence Tomography Angiography of Familial Retinal Arteriolar Tortuosity

      Optical Coherence Tomography Angiography of Familial Retinal Arteriolar Tortuosity

      BACKGROUND AND OBJECTIVE: To analyze the location of familial retinal arterial tortuosity (fRAT) in the three-dimensional structure of retinal capillaries. PATIENTS AND METHODS: Retrospective observational study. Twelve eyes of six patients (two of whom were brothers) were imaged by optical coherence tomography angiography (OCTA). The data from their ocular and systemic examinations were recorded. RESULTS: OCTA imaging clearly showed increased tortuosity of second- and third-order retinal arteries in all cases, visible in the superficial vascular plexus (SVP) up to the arteriole termination in the capillaries. No change was visible in the deep capillary plexus (DCP). CONCLUSIONS: OCTA shows that fRAT ...

    3. Clinical applications of optical coherence tomography angiography: What we have learnt in the first 3 years

      Clinical applications of optical coherence tomography angiography: What we have learnt in the first 3 years

      A review of the literature from 2014 to 2016 was conducted, focusing on the results of optical coherence tomography angiography in different chorioretinal diseases. In only 3 years, optical coherence tomography angiography has been shown to be an effective tool for diagnosing choroidal neovascularization complicating age-related macular degeneration, pathologic myopia, and inflammatory conditions. The technique has sometimes been considered superior to conventional multimodal imaging, for example, in choroidal neovascularization associated with chronic central serous chorioretinopathy or multifocal choroiditis. In retinal vascular diseases, optical coherence tomography angiography has helped to understand the condition described as paracentral acute middle maculopathy and has ...

      Optical Coherence Tomography in Group 2A Idiopathic Juxtafoveolar Retinal Telangiectasis

      Objective To describe the changes observed with optical coherence tomography in group 2A idiopathic juxtafoveolar retinal telangiectasis. Methods We retrospectively reviewed the medical records of 13 patients (25 eyes). All eyes underwent optical coherence tomography examination consisting of 6 radial scans, fundus color photography, and fluorescein angiography. We calculated retinal foveal and central foveal thicknesses from software mapping results. We compared the optical coherence tomography data with fundus photography and fluorescein angiography findings. Results Foveal cystoid spaces, very small or more prominent, were present in 20 of 25 eyes. Some degree of disruption of the inner segment/outer segment photoreceptor ...

      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY TO DISTINGUISH CHOROIDAL NEOVASCULARIZATION FROM MACULAR INFLAMMATORY LESIONS IN MULTIFOCAL CHOROIDITIS

      Purpose: To characterize the macular lesions in multifocal choroiditis using multimodal imaging (MMI) and to evaluate optical coherence tomography angiography (OCTA) in distinguishing neovascular from inflammatory lesions. Methods: Retrospective review of medical records of consecutive patients diagnosed with multifocal choroiditis and macular involvement, between September 2014 and May 2016, were included. All patients underwent standard examination and MMI, including fundus color photography, fundus autofluorescence, fluorescein angiography, and spectral domain optical coherence tomography. They also underwent OCTA examination. Multimodal imaging and OCTA characteristics of inflammatory lesions and choroidal neovascularization (CNV) were compared. Results: Eighteen eyes of 13 patients (11 females) were ...

    6. Predictive Value of Outer Retina En Face OCT Imaging for Geographic Atrophy Progression

      Predictive Value of Outer Retina En Face OCT Imaging for Geographic Atrophy Progression

      Purpose : We determined if the ellipsoid zone (EZ) disruption pattern could be predictive of the geographic atrophy (GA) pattern at 1 year in dry age-related macular degeneration (AMD). Methods : A retrospective study was done of dry eyes in patients with AMD and GA from July to November 2013. Eyes with previous choroidal neovascularization were excluded. Based on spectral domain optical coherence tomography (SD-OCT), the GA was assessed at each timepoint, using a sub-RPE slab derived from the Cirrus Advanced RPE Analysis software encompassing the RPE (sub-RPE slab). Disruption of the EZ also was assessed at baseline, using en face extraction ...

      Imaging in retina units: changes observed during the last 12 years

      Purpose: The last decade has seen many improvements in the imaging of the choroids, retina, and vitreous. However, there are no available data about changes in the practice of imaging in retina units. The present study was therefore undertaken to document the 12-year changes in this practice in retina units in France, particularly the relative changes in the distribution of the different imaging methods. Methods: This retrospective study was performed in 4 different retina units considered to be representative of retina units in France. They comprise 2 departments of ophthalmology in university-based hospitals in Paris and Nantes, one in a ...

    11. Optical Coherence Tomography Of Retinal Pigment Epithelium Folds.

      In four cases of retinal pigment epithelium (RPE) folds with a fingerprint image, optical coherence tomography (OCT) 3 showed folding in the RPE layer, without folding of other layers of the fundus. Thus, OCT validated the initial hypothesis by Schatz et al, who interpreted this fingerprint pattern as RPE folds.Page: 309DOI: 10.1097/ICB.0b013e3180f6067fAuthors: Cohen, Salomon Y.
