2016
To report the long-term anatomical and functional outcomes of patients with choroidal neovascularization secondary to age-related macular degeneration treated with intravitreal bevacizumab (IVB).Retrospective case series. Patients diagnosed with subfoveal choroidal neovascularization secondary to age-related macular degeneration that were treated with at least 1 intravitreal injection of 1.25 mg of IVB and had a minimum follow-up of 60 months. Patients underwent best-corrected Snellen visual acuity testing, optical coherence tomography, and ophthalmoscopic examination at baseline and follow-up visits.Two hundred and forty-seven consecutive patients (292 eyes) were included. The mean number …
Angioid streak-related choroidal neovascularization treated by intravitreal ranibizumab.
2010
PURPOSE The purpose of this study was to report the visual outcome of intravitreal therapy with ranibizumab of choroidal neovascularization secondary to angioid streaks after 1-year follow-up. METHODS Nine patients (age, 58 +/- 4 years; range, 53-65 years) were treated with off-label intravitreal injections of 0.3 mg ranibizumab. Primary outcomes were best-corrected visual acuity changes (Early Treatment Diabetic Retinopathy Study logarithm of the minimum angle of resolution and letters) and optical coherence tomography macular thickness changes. RESULTS Mean follow-up was 14 months (+/-2; range, 12-18 months). Mean visual acuity was 0.52 logarithm of the minimum angle of resolution and 30 …
Best-corrected visual acuity and retinal thickness are associated with improved cortical visual processing in treated wet AMD patients
2015
Purpose In response to anti-VEGF treatment for wet AMD retinal anatomy and visual acuity is often remedied. In our previous study, we showed that visual evoked potentials (VEP) improve following successful anti-VEGF treatment. The aim of this study was to investigate, how visual acuity and retinal thickness changes are reflected in VEP parameters. Moreover, we wanted to assess the feasibility of VEP as a novel monitoring tool for wet AMD patients. Methods A total of 16 patients and six control subjects were enrolled in this study. Patients received three bevacizumab intravitreal injections. At the beginning of the study and four to 6 weeks after the last injection, the best-corrected visual…
Intravitreal bevacizumab plus grid laser photocoagulation or intravitreal bevacizumab or grid laser photocoagulation for diffuse diabetic macular ede…
2013
To evaluate the anatomical and functional outcomes at 24 months in patients with diffuse diabetic macular edema treated with primary intravitreal bevacizumab (IVB) plus grid laser photocoagulation (GLP) or primary IVB alone or GLP alone.Retrospective, interventional, comparative, multicenter study. We included in this analysis 141 eyes of 120 patients with diffuse diabetic macular edema treated with primary IVB alone (Group A), 120 eyes of 94 patients with GLP therapy (Group B), and 157 eyes of 104 patients treated with IVB plus GLP (Group C).In all 3 groups, the authors observed improvement of Early Treatment Diabetic Retinopathy Study best-corrected visual acuity from baseline to 24-month…
Is Ranibizumab effective in stopping the loss of vision for Choroidal Neovascularization in Pathologic Myopia? A Long Term Follow-up Study
2010
Aim To assess the efficacy and safety of ranibizumab in the treatment of choroidal neovascularisation (CNV) caused by pathologic myopia (PM). Design Prospective, multicentre, interventional case series. Methods 40 eyes of 39 consecutive patients with PM and CNV were treated with ‘on demand’ intravitreal injection of ranibizumab 0.5 mg. Final best corrected visual acuity (BCVA) and its change from baseline were the main outcome measures. Changes in optical coherence tomography (OCT) central retinal thickness (CRT) were a secondary outcome. Results Mean age was 53±13 years and mean refractive error –13.5±6.5 D. Median follow-up was 13.3±2 (range 12–18) months. Fifteen eyes (37.5%) had previou…
Retroespalhamento luminoso das córneas de pacientes com diabete melito dependente e não dependente de insulina: estudo piloto
2017
ABSTRACT Purpose: To compare central corneal backscatter obtained from Scheimpflug images between patients with insulin-dependent and non-insulin-dependent diabetes mellitus (IDDM and NIDDM, respectively) and healthy controls. Methods: Seven patients with IDDM (7 eyes), eleven patients with NIDDM (11 eyes), and sixteen healthy subjects (16 eyes) were included in this pilot study. Scheimpflug imaging system (Pentacam, Oculus Inc., Germany) was used to obtain optical sections of the cornea. Seven meridians were analyzed for each eye, oriented from 70° to 110°. Optical density values for the central 3-mm and 5-mm zones of the cornea were obtained by image analysis using external software. Resu…
Comparing oculomotor efficiency and visual attention between drivers and non-drivers through the Adult Developmental Eye Movement (ADEM) test: A visu…
2021
Objective The objective of this study was to assess and compare drivers’ and non-drivers’ outcomes in the Adult Developmental Eye Movement test (ADEM), a visual-verbal test that measures the time needed to read series of numbers in both a vertical and horizontal reading pattern. A set of driving parameters (i.e., experience, risk exposure, and day and night perceived difficulty) and demographic variables (i.e., age, gender, and academic level) were considered as potential predictors of the test performance. Methods For this cross-sectional study, 302 healthy subjects (age range 20 to 86 years old) completed a self-reported questionnaire aimed at retrieving data on the independent variables…
Visual function comparison of 2 aspheric multifocal intraocular lenses
2011
To compare visual function after bilateral implantation of the multifocal Lentis Mplus LS-312 with a nonrotational symmetrical design (copolymer aspheric) or the Acrysof Restor SN6AD1 +3.0 D (hybrid aspheric) intraocular lens (IOL).Fernández-Vega Ophthalmological Institute, Oviedo, Spain.Comparative case series.Six months postoperatively, corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), the defocus curve, and photopic and mesopic contrast sensitivity with and without glare were measured.The mean CDVA was 0.02 ± 0.06 (SD) with the copolymer aspheric IOL and -0.06 ± 0.05 logMAR with the hybrid aspheric IOL (P=.07) and the mean DCNVA, 0.10 ± 0.06 and -0.0…
Endophthalmitis after intravitreal injections: incidence, presentation, management, and visual outcome
2015
Purpose To report the incidence and characteristics of endophthalmitis after intravitreal injections of anti–vascular endothelial growth factor agents or corticosteroids and to describe the clinical and bacteriologic characteristics, management, and outcome of these eyes with acute endophthalmitis in France. Design Retrospective, nationwide multicenter case series. Methods From January 2, 2008 to June 30, 2013, a total of 316 576 intravitreal injections from 25 French ophthalmic centers were included. For each center, the number of intravitreal injections was determined using billing codes and the injection protocol was recorded. A registry and hospital records were reviewed to identify pat…
Visual acuity and color discrimination in patients with cataracts.
2020
Color vision tests can give information about pathological changes in eye structures. The purpose of our research was to study the color vision sensitivity and visual acuity changes before and after cataract surgery. We used a saturated Farnsworth D15 color vision arrangement test to check color sensitivity changes in confusion line directions. The test is easily perceptible (essential to eldery patients), and it is possible to check color sensitivity changes in tritan, protan, and deutan confusion line directions. The results were analyzed in several ways: by summing the color differences between adjacent caps according to Bowman and averaging the color difference vectors according to Ving…
