    1. Evaluation of the clinical utility of optical coherence tomography angiography in age-related macular degeneration

      Evaluation of the clinical utility of optical coherence tomography angiography in age-related macular degeneration

      Background/Aims To evaluate the ability of optical coherence tomography angiography (OCTA) to identify the presence or absence of choroidal neovascularisation (CNV) and CNV activity in age-related macular degeneration (AMD). Methods Clinical parameters, fundus fluorescein angiogram and spectral-domain optical coherence tomography (SD-OCT) were used as the gold standard to determine disease activity. OCTA imaging was performed on the same day and was graded by two masked retina specialists for the presence or absence of CNV. Traditional multimodal imaging and OCTA findings were compared. Results One hundred and fifty-two eyes of 106 patients with AMD were retrospectively reviewed. Of these, 59 ...

    2. Foveal Avascular Zone Distortion in Epiretinal Membrane by Optical Coherence Tomography Angiography

      Foveal Avascular Zone Distortion in Epiretinal Membrane by Optical Coherence Tomography Angiography

      BACKGROUND AND OBJECTIVE: To show the morphologic changes on the foveal avascular zone (FAZ) in patients with epiretinal membrane (ERM) using optical coherence tomography angiography (OCTA) and to demonstrate the correlation between distortion of FAZ and features of the ERM. PATIENTS AND METHODS: FAZ eccentricity index (longest diameter of FAZ/shortest diameter of FAZ) was measured in 52 patients with ERM and compared with 27 healthy subjects' values. The density of the ERM was quantified using a grading scale (0–3) on multicolor scanning laser images, and spectral-domain OCT characteristics of the eyes were assessed. RESULTS: Of the 52 eyes ...

    3. ANATOMICAL AND FUNCTIONAL TESTING IN DIABETIC PATIENTS WITHOUT RETINOPATHY: Results of Optical Coherence Tomography Angiography and Visual Acuity Under Varying Contrast and Luminance Conditions

      ANATOMICAL AND FUNCTIONAL TESTING IN DIABETIC PATIENTS WITHOUT RETINOPATHY: Results of Optical Coherence Tomography Angiography and Visual Acuity Under Varying Contrast and Luminance Conditions

      Purpose: To assess early retinal microvascular and functional changes in diabetic patients without clinical evidence of diabetic retinopathy with optical coherence tomography angiography and central visual analyzer. Methods: This was an observational case–control study of diabetic patients without diabetic retinopathy and nondiabetic controls. Patients underwent optical coherence tomography angiography imaging and visual acuity testing using the central visual analyzer. The foveal avascular zone area and the capillary density in the superficial and deep capillary plexuses were measured manually by a masked grader. Results: Sixty eyes from 35 diabetic patients were included in the study group, and 45 eyes from ...

    4. Handheld OCT Angiography and Ultra–Wide-Field OCT in Retinopathy of Prematurity

      Handheld OCT Angiography and Ultra–Wide-Field OCT in Retinopathy of Prematurity

      Importance Retinopathy of prematurity (ROP) is a leading cause of childhood blindness worldwide. Optical coherence tomography (OCT) has improved the care of adults with vitreoretinal disease, and OCT angiography (OCTA) is demonstrating promise as a technique to visualize the retinal vasculature with lower risk and cost than fluorescein angiography. However, to date, there are no commercially available devices able to obtain ultra–wide-field OCT or OCTA images in neonates. Objective To obtain ultra–wide-field OCT and OCTA images in neonates with ROP using a prototype handheld OCT and OCTA device. Design, Setting, and Participants This observational case series was conducted ...

    5. REPRODUCIBILITY OF VESSEL DENSITY MEASUREMENT WITH OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN EYES WITH AND WITHOUT RETINOPATHY

      REPRODUCIBILITY OF VESSEL DENSITY MEASUREMENT WITH OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN EYES WITH AND WITHOUT RETINOPATHY

      Purpose: To determine the intravisit and intervisit reproducibility of optical coherence tomography angiography measurements of macular vessel density in eyes with and without retinal diseases. Methods: Fifteen healthy volunteers and 22 patients with retinal diseases underwent repeated optical coherence tomography angiography (Angiovue Imaging System, Optovue Inc) scans after pupil dilation on 2 separate visit days. For each visit day, the eyes were scanned twice. Vessel density defined as the proportion of vessel area with flowing blood over the total measurement area was calculated using Angiovue software. Intravisit and intervisit reproducibility were summarized as coefficient of variations and intraclass correlation coefficients ...
