      Swept-Source Optical Coherence Tomography Angiography Assessment Of Fellow Eyes In Coats Disease

      Purpose: To assess foveal and parafoveal vasculature at superficial capillary plexus (SCP), deep capillary plexus, and choriocapillaris using optical coherence tomography angiography in the fellow eyes of patients with Coats disease . Methods: Observational and prospective case series. Thirteen patients with unilateral Coats and 14 healthy age- and sex-matched controls were consecutively recruited at Manchester Royal Eye Hospital and the Department of Ophthalmology of San Raffaele Hospital. Both groups underwent complete ophthalmologic examination, including optical coherence tomography angiography (Topcon Corp) 3 mm × 3 mm scans. Images were imported into ImageJ software and binarized; foveal avascular zone area was manually outlined and ...

      CAPILLARY NETWORK ALTERATIONS IN X-LINKED RETINOSCHISIS IMAGED ON OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      Purpose: To assess foveal and parafoveal vasculature at the superficial capillary plexus, deep capillary plexus, and choriocapillaris of patients with X-linked retinoschisis by means of optical coherence tomography angiography. Methods: Six patients with X-linked retinoschisis (12 eyes) and seven healthy controls (14 eyes) were recruited and underwent complete ophthalmologic examination, including best-corrected visual acuity, dilated fundoscopy, and 3 × 3-mm optical coherence tomography angiography macular scans (DRI OCT Triton; Topcon Corp). After segmentation and quality review, optical coherence tomography angiography slabs were imported into ImageJ 1.50 (NIH; Bethesda) and digitally binarized. Quantification of vessel density was performed after foveal avascular ...

    3. Swept-source Optical Coherence Tomography of Retinal Cavernous Hemangioma: A New Imaging Modality

      Swept-source Optical Coherence Tomography of Retinal Cavernous Hemangioma: A New Imaging Modality

      The authors report a new, non-invasive diagnostic method in the diagnosis of retinal cavernous hemangioma (RCH). A 6-year-old girl was referred for a non-clearing retinal hemorrhage of 6 months’ duration. Fourier-domain optical coherence tomography (FD-OCT) showed an intraretinal lesion with cystic-like internal appearance. Optical shadowing was present, preventing establishment of any subretinal component to the lesion. Swept-source OCT (SS-OCT) showed an intraretinal lesion consisting of a group of clearly defined grape-like caverns with overlying preretinal tissue. Wide-field fundus fluorescein angiography (WF-FFA) confirmed the diagnosis of RCH. SS-OCT was superior to FD-OCT in showing the internal anatomy of the RCH and ...

    4. Swept-source optical coherence tomography imaging of the cortical vitreous and the vitreoretinal interface in proliferative diabetic retinopathy: assessment of vitreoschisis, neovascularisation and the internal limiting membrane

      Swept-source optical coherence tomography imaging of the cortical vitreous and the vitreoretinal interface in proliferative diabetic retinopathy: assessment of vitreoschisis, neovascularisation and the internal limiting membrane

      Anomalous posterior vitreous detachment leads to shrinkage of the inner vitreous with the outer precortical vitreous cortex remaining attached to the macula and retina, resulting in vitreoschisis. 1 Sebag and coworkers have reported vitreoschisis in macular disorders, and vitreoschisis has been demonstrated using ultrasonography and histopathology. 2–4 Swept-source OCT (SS-OCT) is a new imaging technology (Atlantis DRI-OCT-1, Topcon, Japan). We demonstrate for the first time in vivo the microstructural tomographic features of and spatial vitreoretinal relationships between vitreoschisis, retinal and optic nerve head neovascularisation, detachment of the internal limiting membrane (ILM) and traction on the neuroretina in proliferative diabetic ...

    5. In Vivo Imaging of Cortical Vitreous Using 1050-nm Swept-Source Deep Range Imaging Optical Coherence Tomography

      In Vivo Imaging of Cortical Vitreous Using 1050-nm Swept-Source Deep Range Imaging Optical Coherence Tomography

      Purpose To image the cortical vitreous, determine the prevalence of the bursa premacularis and space of Martegiani, and measure the dimensions of the bursa using the new 1050-nm swept-source deep range imaging optical coherence tomography (DRI OCT-1 Atlantis). Design Retrospective cross-sectional study. Methods One hundred and nineteen consecutive patients (5-100 years) underwent an OCT scan using 1050-nm swept-source deep range imaging optical coherence tomography. Prevalence of the bursa premacularis and space of Martegiani and the stage of posterior vitreous detachment (PVD) were determined. The horizontal (width) and anteroposterior (depth) dimensions of the bursa were recorded along with the patient's ...

      Fourier-domain optical coherence tomography evaluation of retinal and optic nerve head neovascularisation in proliferative diabetic retinopathy

      Aim To describe the in vivo spatial and morphological vitreoretinal relationships associated with diabetic retinal neovascularisation using Fourier-domain optical coherence tomography (FD-OCT).

    7. Fourier-Domain Optical Coherence Tomography Imaging of Gas Tamponade Following Macular Hole Surgery

      Fourier-Domain Optical Coherence Tomography Imaging of Gas Tamponade Following Macular Hole Surgery
      In this prospective study, the authors report fourier-domain optical coherence tomography (FD-OCT) imaging of gas-inner retinal tamponade following surgery for full-thickness macular hole and evaluate postoperative posturing based on FD-OCT findings. Patients underwent FD-OCT 1 day after pars plana vitrectomy, internal limiting membrane peel, and gas injection. Three-dimensional FD-OCT and high-resolution line scans demonstrated gas-inner retinal tamponade across the macula with the apex of tamponade located at the fovea. Inner and outer retina landmarks could be accurately identified along the curvature of the eye using FD-OCT in x-, y-, and z-planes. No pa-tients required face-down positioning postoperatively based on FD-OCT ...

    8. Spatial and Spectral Imaging of Retinal Laser Photocoagulation Burns

      Spatial and Spectral Imaging of Retinal Laser Photocoagulation Burns

      Purpose: To correlate in vivo spatial and spectral morphologic changes of short to long-pulse 532-nm Nd:YAG retinal laser lesions using Fourier-domain optical coherence tomography (FD OCT), autofluorescence (AF), fluorescein angiography (FA) and multispectral imaging. Methods: Ten eyes with treatment-naive pre-proliferative or proliferative diabetic retinopathy were studied. A titration grid of laser burns at 20-, 100- and 200-milliseconds was applied to the nasal retina, and laser fluence titrated to produce four grades of laser lesion visibility: sub-visible (SV), barely-visible (BV, light-gray), threshold (TH, gray-white), and supra-threshold (ST, white). The AF, FA, FD-OCT, and multispectral imaging were performed 1-week before laser ...

    9. Nidek MP-1 microperimetry and Fourier domain optical coherence tomography (FD-OCT) in X linked retinoschisis

      Nidek MP-1 microperimetry and Fourier domain optical coherence tomography (FD-OCT) in X linked retinoschisis

      X linked retinoschisis (XLRS) is a frequent cause of macular dystrophy in males with an estimated prevalence of between 1 in 15 000 and 1 in 30 000. The diagnosis is based on the presence of central and peripheral schisis within the inner retina and supported by electroretinography, which shows a characteristic electronegative response to a bright flash in the dark-adapted state.1 Fundus related perimetry or microperimetry is a useful tool for assessing macular function and mapping central visual fields, scotomas and fixation behaviour.2 The MP-1 microperimeter (Nidek technologies, Padua, Italy) utilises an LCD microperimeter and allows a ...

    11. Fundus Autofluorescence and Fourier-Domain Optical Coherence Tomography Imaging of 10 and 20 millisecond Pascal(R) Retinal Photocoagulation Treatment

      Aim: To report the evolution of pattern scanning laser (Pascal®) photocoagulation burns in the treatment of diabetic retinopathy, using Fourier-Domain optical coherence tomography (FD-OCT) and fundus autofluorescence (AF), and to evaluate these characteristics with clinically visible alterations in outer retina (OR) and retinal pigment epithelium (RPE). Methods: Standard red-free and colour fundus photography (FP), FD-OCT, and fundus camera-based AF were performed in 17 eyes of 11 patients following macular and panretinal photocoagulation (PRP). Results: One hour following Pascal® application, visibility of threshold burns on FP was incomplete. AF enabled visualization of complete treatment arrays at one hour, with hypo-autofluorescence at ...
