PURPOSE: To determine whether the presence of vitreomacular interface abnormalities (VMIA) in patients with diabetic macular oedema (DMO) modifies the response to ranibizumab. METHODS: Medical records and spectral-domain optical coherence tomography (SD-OCT) scans of consecutive patients with centre-involving DMO initiating therapy with ranibizumab between December 2013 and March 2014 at the Belfast Health and Social Care Trust were reviewed. Patients were identified through an electronic database...

BACKGROUND AND OBJECTIVE: Stereotactic radiotherapy (SRT) is a new adjuvant treatment modality that has been shown to reduce the need for repetitive intravitreal injections (IVIs) in patients with neovascular age-related macular degeneration (nAMD). The authors aimed to determine baseline predictors of clinical response to SRT. PATIENTS AND METHODS: This was a retrospective, observational case series of patients with nAMD who underwent SRT and subsequently had at least 12 months of complete follow-up...

BACKGROUND AND OBJECTIVE: To demonstrate the advantage of optical coherence tomography angiography (OCTA) for the diagnosis and management of proliferative macular telangiectasia type 2 (MacTel2) masquerading as neovascular age-related macular degeneration (AMD). PATIENTS AND METHODS: This is an observational cases series. Three patients referred with the diagnosis of neovascular AMD were identified in this retrospective study. In addition to color fundus, fluorescein angiography, and spectral-domain OCT (SD-OCT) imaging, SD-OCTA (AngioPlex; Carl Zeiss Meditec, Dublin, CA) was performed...

PURPOSE: To report a case of deferoxamine-induced retinopathy characterized by electroretinography (ERG), optical coherence tomography angiography (OCT-A), and other multimodal imaging. METHODS: This is an observational case report of one patient. Full-field ERG was performed. OCT-A, spectral-domain optical coherence tomography (SD-OCT), color fundus photography, and fundus autofluorescence were used to characterize the retinopathy induced by deferoxamine use. RESULTS: A 64-year-old man with a history of β-thalassemia intermedia presented with worsening visual acuity, nyctalopia, and electronegative ERG...

PURPOSE: To investigate the effects of cataract grade based on wide-field fundus imaging on macular thickness measured by spectral domain optical coherence tomography (SD-OCT) and its signal-to-noise ratio (SNR). METHODS: Two hundred cataract patients (200 eyes) with preoperative measurements by wide-field fundus imaging and macular SD-OCT were enrolled. Cataract severity was graded from 1 to 4 according to the degree of macular obscuring by cataract artifact in fundus photo images...

Purpose: The aim of this study was to determine whether somatotype influences the risk of hydroxychloroquine (HC) retinopathy (HCR) and whether dosing by real body weight (RBW), ideal body weight (IBW), or the lesser of these better predicts the risk of HCR. Patients and methods: A total of 565 patients taking HC for whom height and weight were recorded and a sensitive ancillary testing modality was used including 10-2 visual fields, spectral domain optical coherence tomography, fundus autofluorescence imaging, and multifocal electroretinography were enrolled...

PURPOSE: We evaluated the applicability of the ISNT rule using Bruch's membrane opening minimum rim width (BMO-MRW) in healthy eyes and eyes with normal tension glaucoma (NTG). METHODS: 124 healthy eyes and 136 NTG eyes were analyzed. Using two-dimensional disc photographs, neuroretinal rim (NRR) thickness was measured at the superior, inferior, nasal, and temporal sides of the optic disc. Using spectral domain-optical coherence tomography (SD-OCT), BMO-MRW was measured at the same regions...

PURPOSE: To compare retinal thickness between patients with chronic hypertension without retinopathy, hypertensive retinopathy, Keith-Wagener-Barker Grade IV status, and normal controls using spectral domain optical coherence tomography. METHODS: In this retrospective study, we analyzed patients who visited our retinal clinic from January 2013 to February 2016. Of those included, 58 eyes of 58 patients were in the healthy control group (Group A), 37 eyes of 37 patients were in the chronic hypertension without retinopathy group (disease duration of at least 10 years; Group B), and 31 eyes of 31 patients with relieved hypertensive retinopathy (Grade IV hypertensive retinopathy a year or more ago but no longer had hypertensive retinopathy at the time of the study; Group C)...

Background: The retinal changes have been identified in morphology and function in Parkinson's disease (PD). However, the controversial results suggest that it is incredible that only using a single method for testing retinal change to evaluate Parkinson's disease. The aim of this study was to assess retinal changes and increase the diagnostic efficacy of Parkinson's disease with a combination of multifocal electroretinogram (mf-ERG) and spectral domain optical coherence tomography (SD-OCT) examinations...
