To identify progression of nonproliferative diabetic retinopathy (NPDR) in patients with type 2 diabetes by combining optical coherence tomography angiography (OCTA) metrics and color fundus photography (CFP) images. This study was a post hoc analysis of a prospective longitudinal cohort study (CORDIS, NCT03696810) with 2-year duration. This study enrolled 122 eyes. Ophthalmological examinations included OCTA a...
Introdução: As lentes multifocais (mLIO) estão associadas a fenómenos ópticos indesejados, que contribuem para a insatisfação dos doentes no pós-operatório. Os resultados reportados pelos doentes são indicadores de qualidade cada vez mais valorizados na avaliação dos resultados da cirurgia com mIOL. A tolerância individual aos halos e aos brilhos à volta das luzes e, consequentemente, a satisfação dos doentes n...
BACKGROUND/OBJECTIVES: To characterise the prevalence and three-year progression of centre-involving diabetic macular oedema (CI-DMO) in minimal to moderate non-proliferative diabetic retinopathy, using optical coherence tomography (OCT) and measurements of retinal fluid using tissue optical reflectivity ratios (OCT-Leakage). METHODS/METHODS: Seventy-four eyes from 74 patients were followed in a 3-year prospect...
Diabetic retinopathy (DR) is both a microangiopathy and a neurodegenerative disease. However, the connections between both changes are not well known. To characterise the longitudinal retinal ganglion cell layer + inner plexiform layer (GCL + IPL) changes and their association with microvascular changes in type-2 diabetes (T2D) patients with nonproliferative diabetic retinopathy (NPDR). This two-year prospectiv...
The aim of the study was to characterize the 2-year progression of risk phenotypes of nonproliferative diabetic retinopathy (NPDR) in type 2 diabetes (T2D) phenotype C, or ischemic phenotype, identified by decreased skeletonized retinal vessel density (VD), ≥2 SD over normal values, and phenotype B, or edema phenotype, identified by increased retinal thickness, i.e., subclinical macular edema, and no significan...

INTRODUÇÃO: O nosso objectivo foi avaliar comparativamente a previsão de fórmulas de terceira e nova geração (Barrett Universal II, Kane e Hill-RBF 3.0) no cálculo de lentes intraocula- res (LIO) com e sem o uso de um novo ajuste de comprimento axial (CA) na previsão dos resulta- dos refrativos de olhos com baixo CA. MÉTODOS: Estudo retrospectivo que inclui olhos com CA inferior a 22,0 mm submetidos a ...
Introduction: We characterized the progression of different diabetic retinopathy (DR) phenotypes in type 2 diabetes (T2D). Methods: A prospective longitudinal cohort study (CORDIS, NCT03696810) was conducted with three visits (baseline, 6 months, and 1 year). Demographic and systemic data included age, sex, diabetes duration, lipid profile, and hemoglobin A1c (HbA1c). Ophthalmological examinations included best...
INTRODUÇÃO: Os resultados da cirurgia de catarata podem ser melhorados através de uma abordagem baseada em dados: tracking de outcomes (acuidade visual, refração residual e complicações), bem como otimização (fórmulas, constantes, SIA, ...). A maioria dos sistemas de registo em saúde em oftalmologia não é desenhada para estas tarefas em específico. Ferramentas de software alternativas que implement...
