This cross-sectional study evaluated the relationship between 1) functional and structural measurements of neurodegeneration in initial stages diabetic retinopathy (DR) 2) presence early microvascular impairment. We analyzed baseline data 449 patients with type 2 diabetes enrolled European Consortium for Early Treatment Diabetic Retinopathy (EUROCONDOR) (NCT01726075). Functional studies by multifocal electroretinography (mfERG) neurodysfunction, using spectral domain optical coherence...
<h3>Purpose</h3> To analyse and compare the classification of eyes with diabetic retinopathy using fluorescein angiography (FA) optical coherence tomography (OCTA) performed either AngioPlex or AngioVue. <h3>Methods</h3> This was an observational cross-sectional study 50 from 26 subjects. Two independent graders classified FA angiograms, to assess presence severity several characteristics according ETDRS Report 11, a similar evaluation for each 3×3 mm OCTA image superficial retinal layer...
The primary objective of this study was to assess whether the topical administration two neuroprotective drugs (brimonidine and somatostatin) could prevent or arrest retinal neurodysfunction in patients with type 2 diabetes. For purpose, adults aged between 45 75 years a diabetes duration ≥5 an Early Treatment Diabetic Retinopathy Study (ETDRS) level ≤35 were randomly assigned one three arms: placebo, somatostatin, brimonidine. outcome change implicit time (IT) assessed by multifocal...
In Brief Purpose: To analyze the effect of anti–vascular endothelial growth factor agents (anti-VEGF) in submacular choroidal thickness (CT) diabetic retinopathy (DR) patients. Methods: Cross-sectional study, which included 25 DR patients (50 eyes) divided 2 groups, according to stage and previous treatments: nonproliferative diffuse macular edema both eyes, submitted laser eyes anti-VEGF injection only 1 eye (nonproliferative + group, n = 11); proliferative treated with panretinal...
To identify baseline optical coherence tomography morphologic characteristics predicting the visual response to anti-vascular endothelial growth factor therapy in diabetic macular edema.Sixty-seven patients with edema completed a prospective, observational study (NCT01947881-CHARTRES). All received monthly intravitreal injections of Lucentis for 3 months followed by PRN treatment and underwent best-corrected acuity measurements spectral domain at Baseline, Months 1, 2, 3, 6. Visual was...
To evaluate the age- and gender-specific prevalence of early late age-related macular degeneration (AMD) in a Portuguese population-based sample.All patients aged ≥55 years primary health-care unit were recruited for cross-sectional study. Responders underwent complete ophthalmological examination digital fundus imaging. Early AMD was defined according to International Age-Related Macular Epidemiological Study Group Classification, adopted staging same as that used Rotterdam The...
To evaluate long-term results and predictors of efficacy in patients with macular edema due to retinal vein occlusion (RVO) treated intravitreal ranibizumab a clinical practice setting.The records minimum follow-up 3 years were retrospectively analyzed. Sixteen eyes branch RVO (BRVO) 16 central (CRVO) included. All performed cross-sectional evaluation best-corrected visual acuity (BCVA), spectral domain optical coherence tomography fluorescein angiography. The foveal avascular zone (FAZ) was...
Web archives already hold together more than 534 billion files and this number continues to grow as new initiatives arise. Searching on all versions of these acquired throughout time is challenging, since users expect fast precise answers from web the ones provided by current search engines. This work studies, for first time, how improve effectiveness archives, including creation novel temporal features that explore correlation found between document persistence relevance. The was analyzed...
Abstract Purpose To determine the age‐ and sex‐specific prevalence of early late age‐related macular degeneration ( AMD ) in two P ortuguese population‐based samples to identify its risk factors. Population A population 6023 adults aged ≥55 years was recruited from primary healthcare units central region ortugal – one a coastal n = 3000) another an inland town 3023). Methods Cross‐sectional study. Participants were enrolled locations between ugust 2009 O ctober 2013. Responders underwent...
<b><i>Purpose:</i></b> To explore phenotype-genotype correlations that may contribute to a better understanding of diabetic retinopathy (DR). <b><i>Procedures:</i></b> An exploratory association study was performed identify genetic variants associated with non-proliferative DR (NPDR) in 307 type 2 patients who were previously stratified into 3 different phenotypes NPDR progression. The genotyped for 174 single nucleotide polymorphisms 11...
The web is the primary means of communication in developed societies. It contains descriptions recent events generated through distinct perspectives. Thus, a valuable resource for contemporary historical research. However, its information extremely ephemeral. Several research studies have shown that only small amount remains available on longer than one year. Web archiving aims to acquire, preserve and provide access published online. In April 2013, there were at least sixty four initiatives...
Web archives already hold more than 282 billion documents and users demand full-text search to explore this historical information. This survey provides an overview of web archive architectures designed for time-travel search, i.e. on the within a user-specified time interval. Performance, scalability ease management are important aspects take in consideration when choosing system architecture. We compare these initialize discussion which architecture is suitable large-scale archive.
The web was invented to quickly exchange data between scientists, but it became a crucial communication tool connect the world. However, is extremely ephemeral. Most of information published online becomes unavailable and lost forever. There are several initiatives worldwide that struggle archive from before vanishes. search mechanisms access this still limited do not satisfy their users who demand performance similar live-web engines.
This paper describes a video annotation tool based on new and flexible model, that gives several perspectives over the same content. The model was designed in way allows having multiple views data, enabling users with different requirements to have most appropriate interface. These views, video-lenses, highlight specific aspect of content is being annotated. Annotations are made using timeline interface tracks, where each track corresponds given video-lens. format used store exchange...
<b><i>Purpose:</i></b> The aim of this study is to present the largest normative database using multifocal electroretinography (mfERG) in context a multicenter clinical trial. <b><i>Methods:</i></b> This investigational included 156 eyes from 78 Caucasian subjects aged 45-70 years without known ophthalmic disease or diabetes mellitus; were recruited 11 sites setting EUROCONDOR project. Standardized mfERG acquisition (103 hexagons per eye) was...
Web information is ephemeral. Several organizations around the world are struggling to archive from web before it vanishes. However, users demand efficient and effective search mechanisms access already vast collections of historical held by archives. The Portuguese Archive largest full-text searchable publicly available. It supports over 1.2 billion files archived since 1996. This study contributes with an overview lessons learned while developing Archive, focusing on data acquisition,...
